Blonder Tongue Laboratories, Inc., One Jake Brown Road, Old Bridge, New Jersey 08857, Attn.: Peter Pugielli, Chief Financial Officer, telephone number (732) 679-4000. 3 THE COMPANY

Blonder Tongue is a designer, manufacturer and supplier of a comprehensive line of communications products used in the acquisition, conversion, distribution and protection of television signals. The Company's products have gained a dominant position within the private cable market ("Private Cable") which services multiple dwelling units such as apartment complexes and condominiums ("MDU"), hotels, motels and resorts within the lodging industry ("Lodging"), and other facilities including schools, hospitals, prisons and marinas. The Company is currently leveraging its strategic relationships and expertise gained in the Private Cable market to aggressively expand into the franchised cable market ("CATV"). To this end, on March 25, 1998, the Company acquired all of the assets and technology rights of the interdiction product line of Scientific-Atlanta, Inc. ("Scientific") which has been engineered primarily for, and is currently being sold in, the CATV market. Blonder Tongue's product line can be separated, according to function, into the following categories: (i) headend products used by a system operator for signal acquisition, processing and manipulation for further transmission ("Headend Products"), (ii) distribution products used to permit signals to travel to their ultimate destination in a home, apartment unit, hotel room, office or other terminal location ("Distribution Products"), (iii) subscriber products (which include interdiction products) used to control access to programming at the subscriber's location and to split and amplify incoming signals for transmission to multiple sites and for multiple television sets within a site ("Subscriber Products") and (iv) microwave products used to transmit the output of Headend Products to multiple locations using point-to-point communication links in the 18 Ghz range of frequencies ("Microwave Products"). The Company's principal customers are system integrators, primarily in the Private Cable market, which design, package, install and in most instances operate cable systems. Blonder Tongue is a recognized leader in the Private Cable market, offering Private Cable integrators "one-stop shop" convenience in the form of a complete range of high performance, quality products at reasonable prices as well as product engineering, design and support. The Company offers its customers all components necessary to build a cable system, from Headend Products which serve as the core of any system, to ancillary components of the system which transmit, distribute and control access to cable signals. The Company was incorporated in November 1988, under the laws of the State of Delaware as a successor toGPS Acquisition Corp. for the purpose of acquiring the business of Blonder-Tongue Laboratories, Inc., a New Jersey corporation, operating under the same name, which was originally founded in 1950 by Ben H. Tongue and Isaac S. Blonder to design, manufacture and supply a line of electronics and systems equipment principally for the private cable industry. Following the acquisition, we changed our name to Blonder Tongue Laboratories, Inc. Blonder Tongue completed the initial public offering of its shares of Common Stock in 1950.December 1995.

Today, Blonder Tongue is a technology-development and manufacturing company that delivers a wide range of products and services to the telecommunications, cable entertainment and media industry. For 70 years, Blonder Tongue/Drake products have been deployed in a long list of locations, including lodging/hospitality, multi-dwelling units/apartments, broadcast studios/networks, universities/schools, healthcare/hospitals, fitness centers, government facilities/offices, prisons, airports, sports stadiums/arenas, entertainment venues/casinos, retail stores, and small-medium businesses. These applications are variously described as commercial, institutional and/or enterprise environments and will be referred to herein collectively as “CIE”. The Company'scustomers we serve include business entities installing private video and data networks in these environments, whether they are the largest cable television operators, telco or satellite providers, integrators, architects, engineers or the next generation of Internet Protocol Television (“IPTV”) streaming video providers. The technology requirements of these markets change rapidly, and our research and development team is continually delivering high performance, lower cost solutions to meet customers’ needs.

Our strategy is focused on providing a wide range of products to meet the needs of the CIE environments described above, including lodging/hospitality, multi-dwelling units/apartments, broadcast studios/networks, universities/schools, healthcare/hospitals, fitness centers, government facilities/offices, prisons, airports, sports stadiums/arenas, entertainment venues/casinos, retail stores, and small-medium businesses, and to provide offerings that are optimized for an operator’s existing infrastructure, as well as the operator’s future strategy. A key component of this growth strategy is to provide products that deliver the latest technologies (such as IPTV and digital 4K, UHD, HD and SD video content) and have a high performance-to-cost ratio.

In 2019, Blonder Tongue initiated a consumer premise equipment (“CPE”) sales initiative. The CPE products comprise primarily Android-based IPTV set top boxes sold to the Tier 2 and Tier 3 cable and telecommunications service providers. This strategic initiative is designed to secure an in-home position with our product offerings, more intimate, direct relationships with a wide range of service providers, and increased sales of our CIE products by our Premier Distributors to those same service providers. In its first year, the CPE product initiative achieved sales to over 45 different telco, municipal fiber, and cable operators and accounted for approximately 20% of Blonder Tongue’s 2019 revenues. Sales of CPE products were $1,379,000 and $1,498,000 in the third three months of 2020 and 2019 and $3,051,000 and $2,691,000 in the first nine months of 2020 and 2019, respectively.

We have seen a continuing shift in product mix from analog products to digital products and expects this shift to continue. Accordingly, any substantial decrease in sales of analog products without a related increase in digital products or other products could have a material adverse effect on Blonder Tongue’s results of operations, financial condition and cash flows. Sales of digital video headend products were $801,000 and $1,292,000 and sales of analog video headend products were $323,000 and $366,000 in third three months of 2020 and 2019, respectively. Sales of digital video headend products were $2,603,000 and $5,482,000 and sales of analog video headend products were $838,000 and $1,249,000 in the first nine months of 2020 and 2019, respectively.


Like many businesses throughout the United States and the world, we have been adversely affected by the COVID-19 outbreak. Because there are daily developments regarding the outbreak, we are continually assessing the current and anticipated future effects on our business, including how these developments are impacting or may impact our customers, employees and business partners. In our core CIE business, we have experienced a noticeable decline in sales, as many of our customers have significantly reduced their business operations. In our CPE business we have experienced a more substantial reduction in anticipated sales, again as a result of our customers’ significant decrease in their business activities. With uncertainties surrounding the extent to which the COVID-19 outbreak will affect the economy generally, and our customers and business partners in particular, it is impossible for us to predict when conditions will improve to the point that we may reasonably forecast when our sales might return to historical levels. However, we are currently taking steps to significantly reduce our expenses, including adjustments in our staffing (in the form of furloughs as well as some permanent headcount reductions) and reductions in manufacturing activities, which we believe will improve our ability to continue our operations at current levels and meet our obligations to our customers.

Our manufacturing is allocated primarily between our facility in Old Bridge, New Jersey (“Old Bridge Facility”) and key contract manufacturing located in the People’s Republic of China (“PRC”), South Korea and Taiwan. Blonder Tongue currently manufactures most of its digital products, including the NXG product line and latest encoder, transcoder and EdgeQAM collections, at the Old Bridge Facility. Since 2007 we have transitioned and continues to manufacture certain high volume, labor intensive products, including many of our analog and other products, in the PRC, pursuant to manufacturing agreements that govern the production of products that may from time to time be the subject of purchase orders submitted by (and in the discretion of) Blonder Tongue. Although we do not currently anticipate the transfer of any additional products to the PRC or other countries for manufacture, we may do so if business and market conditions make it advantageous to do so. Manufacturing products both domestically at our Old Bridge Facility as well as off shore in the PRC, South Korea and Taiwan, enables Blonder Tongue to realize cost reductions while maintaining a competitive position and time-to-market advantage.

We may, from time to time, provide manufacturing, research and development and product support services for other companies’ products. In 2015, Blonder Tongue entered into an agreement with VBrick Systems, Inc. (“VBrick”) to provide procurement, manufacturing, warehousing and fulfillment support to VBrick for a line of high-end encoder products and sub-assemblies. Sales to VBrick of encoder products were approximately $28,000 and $319,000 in the third three months of 2020 and 2019 and $101,000 and $393,000 in the first nine months of 2020 and 2019, respectively. Sales to VBrick for sub-assemblies were not material in the three months and nine months ended September 30, 2020 or 2019, respectively.

RISK FACTORS

An investment in this Prospectus, the "Company" and "Blonder Tongue" refer to Blonder Tongue Laboratories, Inc. and its subsidiaries. RISK FACTORSour securities involves substantial risks. In evaluating the Company's business and in making a decision to purchase Common Stock, prospective investorsconsultation with your own advisors, you should carefully consider, among other matters, the followingrisk factors in addition to theand other information we include or incorporate by reference in this prospectus and any prospectus supplement before deciding whether to invest in our securities. In particular, you should carefully consider, among other things, the factors described under the caption “Risk Factors” in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2019 and Part II, Item 1A of our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2020, June 30, 2020 and September 30, 2020, as may be updated by our subsequently-filed Current Reports on Form 8-K. If any of the risks contained in andor incorporated by reference into this Prospectus before purchasing the Common Stock offered hereby. Dependence on Certain Large Customers Approximately 46%, 39% and 40% of the Company's revenues in fiscal years 1995, 1996 and 1997, respectively, were derived from sales of products to the Company's five largest customers. In 1997, sales to OpTel, Inc. and LodgeNet Entertainment Corporation each accounted for approximately 16 % of the Company's revenues. For the first three months of 1998, the Company's five largest customers accounted for approximately 55% of the Company's revenues. There can be no assurance thatprospectus or any sales to these customers, individually or as a group, will reach or exceed historical levels in any future period. However, the Company anticipates that these customers will continue to account for a significant portion of the Company's revenues in future periods, although none of them is obligated to purchase any specified amount of products (beyond outstanding purchase orders) or to provide the Company with binding forecasts of product purchases for any future period. The complement of leading customers may shift as the most efficient and better financed integrators grow more rapidly than others. The Company believes that many integrators will grow rapidly, and, as such, the Company's success will depend in part on the viability of those customers and on the Company's ability to maintain its position in the overall marketplace by shifting its emphasis to those customers with the greatest growth and growth prospects. Any substantial decrease or delay in sales to one or more of the Company's leading customers, theprospectus supplement develop into actual events, our business, financial failure of any of these entities, or the Company's inability to develop solid relationships with the integrators which may replace the present leading customers, could have a material adverse effect on the Company'scondition, liquidity, results of operations and financial condition. 4 Need to Manage Growth; Scientific Acquisition The Company has recently experienced a period of significant growth which has placed, and could continue to place, a significant strain on the Company's resources, including its working capital. Cash flow from operations has been insufficient to finance this growth and the Company has relied upon a line of credit to supplement cash generated from operations to finance working capital requirements. The Company's ability to manage growth effectively will require it to continue to improve and expand its operations, including its financial and management information systems and its manufacturing operations and to recruit and retain executive staff and key employees. There can be no assurance that the Company's operations will generate sufficient cash flow or that adequate financing will be available to finance continued growth. The Company's inability to obtain needed equity or debt financing could have a material adverse effect on the Company's results of operations and financial condition. In addition, there can be no assurance that the Company will be able to continue to improve and expand its operations or to recruit and retain high quality executives and key employees. The failure to manage growth effectively would have a material adverse effect on the Company's results of operations and financial condition. In March, 1998, the Company acquired Scientific's interdiction business, including its interdiction product line (the "Acquisition"). The total purchase price consisted of (i) $19 million in cash, (ii) 67,889 shares of the Company's Common Stock, (iii) a Warrant to purchase 150,000 additional shares of the Company's Common Stock at an exercise price of $14.25 per share and (iv) assumption by the Company of certain obligations under executory contracts with vendors and customers and certain warranty obligations and other current liabilities of Scientific's interdiction business. As a result of the Acquisition, the Company acquired a new interdiction product line (the "SMI Product Line") which the Company believes will complement its current interdiction products and will enable it to increase sales in the CATV market. The success of the SMI Product Line will, however, be dependent upon the Company's ability to timely integrate the new products into the Company's existing operations, obtain manufacturing efficiencies, and maintain and increase market share in the CATV market. There can be no assurance that the new products will be successfully integrated by the Company or that such integration will not strain the Company's available management, manufacturing, financial and other resources. There can be no assurance that the Company will maintain the level of sales of the SMI Product Line in the CATV market or that increased sales of the SMI Product Line will not decrease sales of the Company's other products, including the Company's VideoMask(TM) interdiction product line. The Company's inability to integrate the SMI Product Line in a timely manner could have a material adverse effect on the Company's results of operations and financial condition. The Company currently has no commitments with respect to any future acquisitions. The Company, however, frequently evaluates the strategic opportunities available to it and, as part of its strategy to increase growth through acquisition, may in the future pursue acquisitions of additional complementary products, technologies and businesses. Such acquisitions by the Company may result in the diversion of management's attention from the day-to-day operations of the Company's business and may include numerous other risks, including difficulties in the integration of the operations and products, integration and retention of personnel of the acquired companies and certain financial risks. Future acquisitions by the Company may result in dilutive issuances of equity securities, the incurrence of additional debt, reduction of existing cash balances, amortization expenses related to goodwill and other intangible assets and other charges to operations that could have a material adverse effect on the Company's results of operations and financial condition. Changes in Technologies, Industry Standards and Customers' Needs Both the Private Cable industry and the CATV industry are characterized by the continuing advancement of technology, evolving industry standards and changing customer needs. To be successful, the Company must anticipate the evolution of industry standards and changes in customer needs, through the timely development and introduction of new products, enhancement of existing products and licensing of new technology from third parties. Although the Company depends primarily on its own research and development efforts to develop new products and enhancements to its existing products, the Company has and may continue to seek licenses for new technology from third parties when the Company believes that it can obtain such technology more quickly and/or cost-effectively from such third parties than the Company could otherwise develop on its own, or when the desired technology has already been patented by a third party. There can, however, be no assurance that new technology or such licenses will be available on terms acceptable to the Company. There can be no assurance that the Company will anticipate the evolution of industry standards in Private Cable, CATV or the communications industry generally, changes in the market and customer needs, or that technologies and applications under development by the Company will be successfully developed, or if they are successfully developed, that they will achieve market acceptance. If the Company is unable for technological or other reasons to develop and introduce products and applications or to obtain licenses for new technologies from third parties in a timely manner in response to changing market conditions or customer requirements, the Company's results of operations and financial condition would be materially adversely affected. 5 Highly Competitive Market Place All aspects of the Company's business are highly competitive. The Company competes with national, regional and local manufacturers and distributors, including companies larger than itself which have substantially greater resources. Various manufacturers who are suppliers to the Company sell directly as well as through distributors into the CATV and Private Cable marketplaces. Because of the convergence of the cable, telecommunications and computer industries and rapid technological development, new competitors may seek to enter the principal markets served by the Company. Many of these potential competitors have significantly greater financial, technical, manufacturing, marketing, sales and other resources than the Company. The Company expects that direct and indirect competition will increase in the future. Additional competition could have a material adverse effect on the Company's results of operations and financial condition through price reductions, loss of market share and delays in the timing of customer orders and an inability to increase its penetration into the CATV market. Dependence on Cable Industry Capital Spending The Company estimates that approximately 80% of its revenues in fiscal years 1995, 1996 and 1997 came from worldwide sales of its products for use primarily in Private Cable systems. Demand for the Company's products depends to a large extent upon capital spending on Private Cable systems and specifically by Private Cable operators for constructing, rebuilding, maintaining or upgrading their systems. Capital spending by Private Cable operators and, therefore, the Company's sales and profitability, are dependent on a variety of factors, including access by Private Cable operators to financing, demand for their cable services, availability of alternative video delivery technologies, and general economic conditions. In addition, since a principal strategy of the Company's growth plan anticipates deeper penetration into the CATV market, the Company's sales and profitability may in the future be more dependent on capital spending by traditional franchise cable system operators as well as by new entrants to this market planning to over-build existing cable system infrastructures, for constructing, rebuilding, maintaining and upgrading their systems. There can be no assurance that system operators in Private Cable or CATV will continue capital spending for constructing, rebuilding, maintaining, or upgrading their systems. Any substantial decrease or delay in capital spending by Private Cable or CATV operators would have a material adverse effect on the Company's results of operations and financial condition. Dependence on Single Manufacturing Facility The Company operates out of one manufacturing facility in Old Bridge, New Jersey (the "Old Bridge Facility"). While the Company maintains a limited amount of business interruption insurance, a casualty that results in a lengthy interruption of the ability to manufacture at that facility would have a material adverse effect on the Company's results of operations and financial condition. Dependence on Third Party Suppliers The Company purchases several products from sole suppliers for which alternative sources are not available, such as the VideoCipher(R) and DigiCipher(R) encryption systems manufactured by General Instrument Corporation, which are standard encryption methodology employed on United States C-Band and Ku-Band transponders, certain components of EchoStar digital satellite receiver decoders, which are specifically designed to work with the DISH Network(TM), and certain components of Hughes Network Systems digital satellite receivers which are specifically designed to work with DIRECTV(R) programming. Presently, the subscriber modules used in the Company's SMI Product Line acquired from Scientific in March, 1998, are manufactured for the Company by Matsushita Electronic Components Co., Ltd. pursuant to a supply contract. While the Company intends to develop this capability, there are no assurances that it will successfully be able to do so. An inability to timely obtain sufficient quantities of these components could have a material adverse effect on the Company's results of operations and financial condition. In addition, results of operations and financial conditionprospects could be materially and adversely affected, by receipt of a significant number of defective components, an increase in component prices or the inability of the Company to obtain lower component prices in response to competitive pressures on the pricing of the Company's products. Dependence on Internal Sales Force The Company historically maintained contractual relationships with numerous independent sales representatives; however, in February, 1998, the Company terminated almost all of its contractual relationships with its independent sales representatives. The Company intends to retain independent sales representatives only in particular geographic areas, such as the European market, or targeted to specific customer prospects. While management believes its internal sales force has the capacity to maintain or increase sales formerly made through independent sales representatives without the necessity of paying sales commissions, there can be no assurance that the internal sales force can maintain the historic levels of sales formerly made through the independent sales representatives or that additional employees will not need to be hired by the Company to expand the internal sales force. The Company's results of operations and financial condition could be 6 materially adversely affected if the internal sales force cannot maintain and increase the amount of sales formerly produced by the independent sales representatives. Risks of International Operations Sales to customers outside of the United States represented approximately 9%, 5% and 3% of the Company's revenues in fiscal years 1995, 1996 and 1997, respectively. Such sales are subject to certain risks such as changes in foreign government regulations and telecommunications standards, export license requirements, tariffs and taxes, other trade barriers, fluctuations in foreign currency exchange rates, difficulties in staffing and managing foreign operations, and political and economic instability. Fluctuations in currency exchange rates could cause the Company's products to become relatively more expensive to customers in a particular country, leading to a reduction in sales or profitability in that country. There can be no assurance that sales to customers outside the United States will reach or exceed historical levels in the future, or that international markets will continue to develop or that the Company will receive additional contracts to supply its products for use in systems and equipment in international markets. The Company's results of operations and financial condition could be materially adversely affected if international markets do not continue to develop, the Company does not continue to receive additional contracts to supply its products for use in systems and equipment in international markets or the Company's international sales are affected by the other risks of international operations. Limited Proprietary Protection Other than the SMI Product Line acquired by the Company from Scientific, the underlying technology for which is covered by numerous U.S. and international patents, the Company possesses limited patent or registered intellectual property rights with respect to its technology. The Company relies on a combination of contractual rights and trade secret laws to protect its proprietary technology and know-how. There can be no assurance that the Company will be able to protect its technology and know-how or that third parties will not be able to develop similar technology independently. Therefore, existing and potential competitors may be able to develop similar products which compete with the Company's products. Such competition could adversely affect the prices for the Company's products or the Company's market share and could have a material adverse effect upon the Company's results of operations and financial condition. Risk of Patent Infringement Claims While the Company does not believe that its products (including products and technologies licensed from others) infringe the proprietary rights of any third parties, there can be no assurance that infringement or invalidity claims (or claims for indemnification resulting from infringement claims) will not be asserted against the Company or its customers. Damages for violation of third party proprietary rights could be substantial, in some instances are trebled, and could have a material adverse effect on the Company's financial condition and results of operation. Regardless of the validity or the successful assertion of any such claims, the Company would incur significant costs and diversion of resources with respect to the defense thereof which could have a material adverse effect on the Company's financial condition and results of operations. If the Company is unsuccessful in defending any claims or actions that are asserted against the Company or its customers, the Company may seek to obtain a license under a third party's intellectual property rights. There can be no assurance, however, that under such circumstances, a license would be available under reasonable terms or at all. The failure to obtain a license to a third party's intellectual property rights on commercially reasonable terms could have a material adverse effect on the Company's results of operations and financial condition. Risks of Governmental Regulation Private Cable (estimated by the Company to represent approximately 80% of its business), while in some cases subject to certain FCC licensing requirements, is not presently burdened with extensive government regulations. It is possible, however, that regulations could be adopted in the future which impose burdensome restrictions on Private Cable operators resulting in, among other things, barriers to the entry of new competitors or limitations on capital expenditures by Private Cable operators. Any such regulations, if adopted, could have a material adverse effect on the Company's results of operations and financial condition. Operators in the CATV market (estimated by the Company to represent approximately 20% of its business) had been subject to extensive government regulation pursuant to the Cable Television Consumer Protection and Competition Act of 1992, which among other things provided for rate rollbacks for basic tier cable service, further rate reductions under certain circumstances and limitations on future rate increases. The Telecommunications Act of 1996 has deregulated many aspects of CATV system operation and has opened the door to competition among cable operators and telephone companies in each of their respective industries. The Company believes that this legislation will increase the base of potential customers for the Company's products. It is possible, however, that regulations could be adopted in the future which would re-impose burdensome restrictions on CATV operators resulting in, among other things, the grant of exclusive rights or franchises within certain geographical areas. Any increased regulation of CATV could have a material adverse effect on the Company's results of operations and financial condition. 7 Environmental Regulations The Company is subject to a variety of federal, state and local governmental regulations related to the storage, use, discharge and disposal of toxic, volatile or otherwise hazardous chemicals used in its manufacturing processes. The Company does not anticipate material capital expenditures during the remainder of its current fiscal year or during 1999, for compliance with federal, state and local environmental laws and regulations. There can be no assurance, however, that changes in environmental regulations will not result in the need for additional capital expenditures or otherwise impose additional financial burdens on the Company. Further, such regulations could restrict the Company's ability to expand its operations. Any failure by the Company to obtain required permits for, control the use of, or adequately restrict the discharge of, hazardous substances under present or future regulations could subject the Company to substantial liability or could cause its manufacturing operations to be suspended. Such liability or suspension of manufacturing operations could have a material adverse effect on the Company's results of operations and financial condition. Dependence on Key Personnel The Company's future success depends in large part on the continued service of its key executives and technical and management personnel, including James A. Luksch, Chief Executive Officer and President, and Robert J. Palle, Executive Vice President and Chief Operating Officer. The Company maintains and is the beneficiary of $1,000,000 of key man life insurance on each of Mr. Luksch and Mr. Palle. The Company's future success also depends on its ability to continue to attract and retain highly-skilled engineering, manufacturing, marketing and managerial personnel. The competition for such personnel is intense, and the loss of key employees, in particular the principal members of its management and technical staff, could have a material adverse effect on the Company's results of operations and financial condition. Control of the Company by Principal Stockholders, Officers and Directors Immediately following this offering, the Company's principal stockholders, officers and directors will beneficially own approximately 63% of the outstanding shares of the Company's Common Stock. As a result, such persons, acting together, would have the ability to control all matters requiring stockholder approval. The concentration of ownership could have the effect of discouraging offers to acquire the Company or otherwise inhibiting a change in control of the Company, and as a result, may deprive stockholders of an opportunity to sell their stock at higher prices. Potential Issuance of Preferred Stock and other Anti-Takeover Measures The Board of Directors has the authority to issue up to 5,000,000 shares of undesignated Preferred Stock, to determine the powers, preferences and rights and the qualifications, limitations or restrictions granted to or imposed upon any unissued series of undesignated Preferred Stock and to fix the number of shares constituting any series and the designation of such series, without any further vote or action by the Company's stockholders. The Preferred Stock could be issued with voting, liquidation, dividend and other rights superior to the rights of the Common Stock. Furthermore, such Preferred Stock may have other rights, including economic rights, senior to the Common Stock, and as a result, the issuance of such stock could have a material adverse effect on the market value of the Common Stock. In addition, the Company's Restated Certificate of Incorporation eliminates the right of stockholders to act without a meeting, does not provide cumulative voting for the election of directors or the right of stockholders to call special meetings, provides for a classified board of directors, and imposes various procedural requirements which could make it difficult for such stockholders to affect certain corporate actions. These provisions and the Board's ability to issue Preferred Stock may have the effect of deterring hostile takeovers or offers from third parties to acquire the Company, preventing stockholders from receiving a premium for their shares of the Company's Common Stock, or delaying or preventing changes in control or management of the Company. The Company is also afforded the protection of Section 203 of the Delaware General Corporation Law, which could delay or prevent a change in control of the Company, impede a merger, consolidation or other business combination involving the Company or discourage a potential acquiror from making a tender offer or otherwise attempting to obtain control of the Company. Any of these provisions which may have the effect of delaying or preventing a change in control of the Company could have a material adverse effect on the market value of the Company's Common Stock. Dividends Unlikely The Company intends to retain its earnings to finance the growth of its business and therefore does not intend to pay dividends on its Common Stock in the foreseeable future. Potential Volatility of Stock Price Factors such as announcements of technological innovations or new products by the Company, its competitors or third parties, quarterly variations in the Company's actual or anticipated results of operations, failure of revenues or earnings in any quarter to meet the investment community's expectations, and market conditions for emerging growth stocks 8 or cable industry stocks in general may cause the market price of our securities could decline, and you may lose all or part of your investment. Some statements in this prospectus and any prospectus supplement, and in the Company'sdocuments incorporated by reference into this prospectus or any prospectus supplement, including statements relating to the risk factors, constitute forward-looking statements. See the “Cautionary Note Regarding Forward-Looking Statements” section in this prospectus and any prospectus supplement.

SELLING STOCKHOLDERS

Private Placement of Shares of Common Stock and Warrants

On December 14, 2020 we entered into the Securities Purchase Agreement with the Purchasers, pursuant to which we issued and sold to the Purchasers an aggregate of 1,428,571 shares of Common Stock (the “Shares”) and warrants (the “Warrants”) to purchase an aggregate of up to 714,286 shares of Common Stock (the “Warrant Shares”), for aggregate gross proceeds to us of $1 million, before deducting placement agent fees and offering expenses payable by us. The transaction closed on December 15, 2020.

The Warrants have an exercise price of $1.25 per share and are exercisable, in whole or in part, for a period of three years beginning on December 15, 2020. The exercise price and the number of shares of Common Stock issuable upon exercise of each Warrant is subject to appropriate adjustments in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting our Common Stock. Under certain circumstances, the Warrants my be exercised by means of a cashless exercise according to a formula provided in the Warrants.

The Securities Purchase Agreement also includes terms that give the Purchasers certain price protections, providing for adjustments of the number of shares of Common Stock held by them in the event of certain future dilutive securities issuances by us for a period not to exceed 18 months following the closing of the private placement, or such earlier date on which all of the Warrants have been exercised. In addition, the Securities Purchase Agreement provides the Purchasers with a right to participate in certain of our future financings, up to 30% of the amount of such financings, for a period of 24 months following the closing of the private placement.

In certain circumstances, upon the occurrence of a fundamental transaction, a holder of Warrants is entitled to receive, upon any subsequent exercise of the Warrant, for each Warrant Share that would have been issuable upon such exercise of the Warrant immediately prior to the fundamental transaction, at the option of the holder, the number of shares of common stock of the successor or acquiring corporation or of us, depending on which entity is the surviving corporation in the transaction, and any additional consideration receivable as a result of the fundamental transaction by a holder of the number of shares of our Common Stock for which the Warrant is exercisable immediately prior to the fundamental transaction. If holders of our Common Stock are given any choice as to the securities, cash or property to be received in a fundamental transaction, then the holder of the Warrant shall be given the choice as to the additional consideration it receives upon any exercise of the Warrant following the fundamental transaction.

The Securities Purchase Agreement further obligates us to call a special meeting of our stockholders to seek stockholder approval of the issuance of shares of our Common Stock issuable in connection with the private placement (including shares issuable with respect to the Placement Agent Warrants described below) in excess of 19.99% of our outstanding shares of Common Stock, as calculated as of December 15, 2020, in accordance with the requirements of Section 713(a) of the NYSE American Company Guide. Until stockholder approval has been obtained, we are prohibited from issuing more than two million shares of our Common Stock, in the aggregate, pursuant to the Securities Purchase Agreement (including certain anti-dilution provisions thereof), the Warrants and the Placement Agent Warrants.

The Securities Purchase Agreement also requires that we register the resale of the Shares and the Warrant Shares under the Securities Act and, in connection therewith, we entered into the Registration Rights Agreement with the Purchasers. The Registration Rights Agreement obligates us, at our expense, to file a registration statement with the SEC on Form S-3 to register the resale of the Shares and the Warrant Shares by the Purchasers no more than 30 days following December 14, 2020. We are required to use our best efforts to cause the registration statement to be declared effective by the SEC as promptly as possible after its filing, but in any event no later than the 90th calendar day following the date of the Registration Rights Agreement (or, in the event of a “full review” by the SEC, the 120th calendar day following the date of the Registration Rights Agreement). In addition, we are obligated to use our efforts to keep the registration statement continuously effective until the date that all registrable securities covered by the registration statement (i) have been sold thereunder or pursuant to Rule 144 under the Securities Act, or (ii) may be sold without volume or manner-of-sale restrictions pursuant to Rule 144 and without the requirement for us to be in compliance with the current public information requirement of Rule 144.


Pursuant to the Registration Rights Agreement, we are registering the Shares and the Warrant Shares in order to permit the selling stockholders to offer such shares for resale from time to time pursuant to this prospectus. The selling stockholders may also sell, transfer or otherwise dispose of all or a portion of their shares in transactions exempt from the registration requirements of the Securities Act, or pursuant to another effective registration statement covering those shares.

In connection with the private placement, we also agreed to issue to the placement agents and certain persons affiliated with the placement agents (i) fully-vested warrants (the “Placement Agent Vested Warrants”) to purchase an aggregate of up to 100,000 shares of our Common Stock and (ii) contingent warrants (the “Placement Agent Contingent Warrants,” and together with the Placement Agent Vested Warrants, the “Placement Agent Warrants”) to purchase an aggregate of up to an additional 50,001 shares of our Common Stock. The Placement Agent Vested Warrants have an exercise price of $0.70 per share, a term of five years from December 14, 2020, and become exercisable beginning on the earlier of (a) the receipt of the stockholder approval described above and (ii) the exercise or expiration of all of the Warrants. The Placement Agent Contingent Warrants have an exercise price of $1.25 per share, a term of five years from December 14, 2020, and become exercisable if, and to the extent, holders of the Warrants exercise such Warrants, and are only exercisable, in any event, if the stockholder approval described above is obtained. The exercise price and the number of shares of Common Stock issuable upon exercise of each Placement Agent Vested Warrant and each Placement Agent Contingent Warrant is subject to appropriate adjustments in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting the Common Stock. The shares issuable upon exercise of the Placement Agent Vested Warrants and the Placement Agent Contingent Warrants are not being registered for resale pursuant to this registration statement.

We are registering the shares of Common Stock in order to permit the selling stockholders to offer the shares for resale from time to time. Except for the ownership of the shares of Common Stock and the Warrants, the selling stockholders have not had any material relationship with us within the past three years except for their ownership of the shares of Common Stock and the Warrants.

The table below lists the selling stockholders and other information regarding the beneficial ownership of the shares of Common Stock by each of the selling stockholders. The second column lists the number of shares of Common Stock beneficially owned by each selling stockholder, based on its ownership of the shares of Common Stock and Warrants, as of January 7, 2021, assuming exercise of the Warrants held by the selling stockholders on that date, without regard to any limitations on exercises.

The fourth column assumes the sale of all of the shares offered by the selling stockholders pursuant to this prospectus.

Under the terms of the Warrants, a selling stockholder may not exercise the Warrants to the extent such exercise would cause such selling stockholder, together with its affiliates and attribution parties, to beneficially own a number of shares of Common Stock which would exceed 4.99% of our then outstanding Common Stock following such exercise, excluding for purposes of such determination shares of Common Stock issuable upon exercise of the warrants which have not been exercised.

DESCRIPTION OF SECURITIES

The following description summarizes the material terms of the Common Stock that may be offered and sold by the selling stockholders under this prospectus. The following description provides a summary of the terms of our Common Stock, but does not purport to be complete and is subject to and qualified by reference to our certificate of incorporation and bylaws, as amended to date, which have been filed with or incorporated by reference in the registration statement of which this prospectus is a part.

The description below does not contain all of the information that you might find useful or that might be important to you. You should refer to the provisions of our certificate of incorporation and bylaws because they, and not the summaries, define the rights of holders of shares of our Common Stock. These documents are available as described under the heading “Where You Can Find More Information.”

General

Our certificate of incorporation authorizes the issuance of up to 25,000,000 shares of Common Stock and 5,000,000 shares of preferred stock. The rights and preferences of the preferred stock may be established from time to time by our board of directors. As of January 12, 2021, there were 11,557,663 shares of Common Stock issued and outstanding and no shares of preferred stock issued and outstanding.

Voting Rights

Except as otherwise required by law and except as provided by the terms of any other class or series of stock, holders of Common Stock have the exclusive power to vote on all matters presented to our stockholders, including the election of directors. Each holder of Common Stock is entitled to one vote per share, and each holder does not have cumulative voting rights. Accordingly, the holders of a majority of the shares of Common Stock entitled to vote in any election of directors can elect all of the directors standing for election if they so choose. All matters are decided by the vote of a majority in voting interest of the stockholders present in person or by proxy and voting at any meeting of the stockholders during which a quorum is present, except as otherwise provided in our certificate of incorporation, our bylaws or by applicable law.

Because our certificate of incorporation permits our board of directors to set the voting rights of preferred stock, it is possible that holders of one or more series of preferred stock issued in the future could have voting rights that might limit the effect of the voting rights of holders of Common Stock.

Dividend Rights; Liquidation Rights

Subject to preferences that may be applicable to any then outstanding preferred stock, holders of Common Stock are entitled to receive ratably those dividends, if any, as may be declared from time to time by the board of directors out of legally available funds. In addition, we may be party to one or more agreements, such as loan agreements and credit facilities, that will contractually limit our ability to pay dividends.

Because our articles of incorporation permit our board of directors to set the dividend rights of preferred shares, it is possible that holders of one or more series of preferred shares issued in the future could have dividend rights that differ from those of the holders of our Common Stock. If the holders of a class or series of preferred stock is given dividend rights, the right of holders of preferred shares to receive dividends could have priority over the right of holders of our Common Stock to receive dividends.

We have followed and presently intend to continue following a policy of retaining earnings. We have not historically declared or paid dividends on our Common Stock, and we do not expect to do so in the foreseeable future. Any future determination relating to our dividend policy will be made at the discretion of our board of directors and will depend on a number of factors, including our earnings and financial condition, liquidity and capital requirements, the general economic and regulatory climate, our ability to service any equity or debt obligations senior to our Common Stock, and other factors deemed relevant by our board of directors.


In the event of our liquidation, dissolution or winding up, holders of Common Stock will be entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of our debts and other liabilities and the satisfaction of any liquidation preference granted to the holders of any outstanding shares of preferred stock.

Redemption, Preemptive Rights and Repurchase Provisions

Holders of Common Stock have no preemptive or conversion rights or other subscription rights, and there are no redemption, repurchase or sinking fund provisions applicable to the Common Stock. Discretionary repurchases of our Common Stock may be subject to contractual prohibitions or limitations, including prohibitions or limitations included in loan agreements and credit facilities.

Potential Effects of Issuance of Preferred Stock

Under the terms of our certificate of incorporation, the board of directors is authorized, subject to any limitations prescribed by law, without stockholder approval, to issue shares of preferred stock in one or more series. Each such series of preferred stock will have such rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences, as shall be determined by the board of directors.

The purpose of authorizing the board of directors to issue preferred stock and determine its rights and preferences is to eliminate delays associated with a stockholder vote on specific issuances. The issuance of preferred stock, while providing desirable flexibility in connection with a variety of corporate purposes, could have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from acquiring, a majority of our outstanding voting stock.

The effects of issuing preferred stock could include one or more of the following:

decreasing the amount of earnings and assets available for distribution to holders of Common Stock;
restricting dividends on the Common Stock;
diluting the voting power of the Common Stock; or
delaying, deferring or preventing changes in our control or management.

Effect of Certain Provisions of our Certificate of Incorporation and Bylaws and the Delaware Anti-Takeover Statute

Some provisions of Delaware law and our certificate of incorporation and bylaws could make the following transactions more difficult:

acquisition of us by means of a non-negotiated tender offer or similar transaction;
a change of control by means of a proxy contest or otherwise; or
removal of our incumbent directors.

It is possible that these provisions could make it more difficult to accomplish or could deter transactions that shareholders may otherwise consider to be in their best interest or in our best interest, including transactions which provide for payment of a premium over the market price for our shares.

These provisions, summarized below, are intended to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors. We believe that the benefits of the increased protection of our potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging these proposals because negotiation of these proposals could result in an improvement of their terms.


Provisions of Our Governing Documents. Our articles of incorporation and bylaws include provisions that may have the effects summarized above. These provisions:

empower our board of directors, without stockholder approval, to issue preferred stock, the terms of which, including voting power, are set by our board of directors;
divide our board of directors into three classes serving staggered three-year terms;
restrict the ability of stockholders to remove directors;
prohibit action by the stockholders without a stockholder meeting;
eliminate cumulative voting in elections of directors;
require that shares representing at least two-thirds of the total voting power approve any amendment to or repeal of our bylaws;
require advance notice of nominations for the election of directors and the presentation of stockholder proposals at meetings of stockholders; and
allow the board of directors to increase or decrease the number of directors.

Provisions of Applicable Law – Delaware Anti-Takeover Statute. We are subject to Section 203 of the Delaware General Corporation Law (“DGCL”). This law prohibits a publicly held Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date that the stockholder became an “interested stockholder” unless:

prior to the date of the transaction, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;
upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the number of shares outstanding those shares owned by persons who are directors and also officers and by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or
on or subsequent to the date of the transaction, the business combination is approved by the board of directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least two-thirds of the outstanding voting stock which is not owned by the interested stockholder.

Section 203 defines “business combination” to include:

any merger or consolidation involving the corporation and the interested stockholder;
any sale, transfer, pledge or other disposition of 10% or more of our assets involving the interested stockholder;
in general, any transaction that results in the issuance or transfer by us of any of our stock to the interested stockholder; or
the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.

In general, Section 203 of the DGCL defines an “interested stockholder” as an entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by the entity or person.


Limitation of Liability and Indemnification

Section 145 of the DGCL allows us to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was our director, officer, employee or agent, or is or was serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to our best interests, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful. Section 145 further allows us to indemnify any such person serving in any such capacity who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in our favor, by reason of the fact that the person is or was our director, officer, employee or agent, or is or was serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to our best interests and except that no indemnification is permitted in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to us, unless and only to the extent that the Delaware Court of Chancery or the court in which such action or suit was brought determines that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which such court deems proper.

Section 102(b)(7) of the DGCL permits us to include in our certificate of incorporation a provision eliminating or limiting the personal liability of a director to us or our stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director (i) for any breach of the director’s duty of loyalty, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL (relating to unlawful payment of dividends and unlawful stock purchase and redemption) or (iv) for any transaction from which the director derived an improper personal benefit.

Our certificate of incorporation provides that our directors shall not be liable to Blonder Tongue or our stockholders for monetary damages for breach of fiduciary duty as a director except to the extent that exculpation from liabilities is not permitted under the DGCL as in effect at the time such liability is determined. In addition, our certificate of incorporation and our bylaws each include provisions requiring us to indemnify directors and officers to the fullest extent permitted by the DGCL. Our certificate of incorporation and bylaws provide that any person made a party or threatened to be made a party to a threatened, pending or completed action, suit or proceeding by reason of the fact that such person is or was a director or officer of ours, is or was serving at our request as a director or officer of another corporation or enterprise, including service with respect to an employee benefit plan, shall be indemnified by us against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding to the fullest extent authorized from time to time by the DGCL. The rights of indemnification are not exclusive of any other rights to which those seeking indemnification may be entitled and shall continue as to a person who ceases to be a director, officer, employee or agent.

We have obtained director and officer liability insurance under which, subject to the limitations of such policies, coverage will be provided (a) to directors and officers against loss arising from claims made by reason of breach of fiduciary duty or other wrongful acts as a director or officer, including claims relating to public securities matters and (b) to us with respect to payments which we may make to our directors and officers pursuant to the indemnification provisions summarized above or otherwise as a matter of law.

We also have entered into indemnification agreements with our directors and officers. The indemnification agreements provide directors and officers with further indemnification to the maximum extent permitted by the DGCL.

We believe that the foregoing policies and provisions of our governing documents are necessary to attract and retain qualified officers and directors. Insofar as indemnification for liabilities arising under the Securities Act may be permitted with respect to our directors, officers or persons controlling us pursuant to the foregoing provisions, we have been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.
