           Re:      Registration Statement on Form S-8

Dear Mr. Luksch:

           We have acted as counsel to and for Blonder Tongue Laboratories,
Inc., a Delaware corporation (the "Company"), in connection with the preparation
and filing with the Securities and Exchange Commission of a registration
statement on Form S-8 (the "Registration Statement"), for the purpose of
registering under the Securities Act of 1933, as amended, 575,000 shares (the
"Shares") of the Company's common stock, $.001 par value per share (the "Common
Stock"). The Shares are issuable upon the exercise of certain options (the
"Options") granted or to be granted under the Company's 1995 Long Term Incentive
Plan, as amended (the "1995 Plan") and the Company's Amended and Restated 1996
Director Option Plan (the "Director Plan," and together with the 1995 Plan, the
"Plans").

           In our capacity as counsel, we have been requested to render the
opinions set forth in this letter and, in connection therewith, we have reviewed
the following documents: (i) the Registration Statement, (ii) the Plans, (iii)
Restated Certificate of Incorporation of the Company, certified as true and
correct by the Secretary of the Company, (iv) Bylaws of the Company, certified
as true and correct by the Secretary of the Company, (v) certain minutes of
meetings or unanimous consents of the Board of Directors and stockholders of the

Company, and (vi) the form of option agreement executed or to be executed by the
Company and each optionee (the "Option Agreement").

           In rendering this opinion, we have assumed and relied upon, without
independent investigation, (i) the authenticity, completeness, truth and due
authorization and execution of all documents submitted to us as originals, (ii)
the genuineness of all signatures on all documents submitted to us as originals,
and (iii) the conformity to the originals of all documents submitted to us as
certified or photostatic copies.

           The law covered by the opinion expressed herein is limited to (a) the
Federal statutes, judicial decisions and rules and regulations of the
governmental agencies of the United States of America and (b) the Delaware
General Corporation Law, as amended.

           This opinion letter is given only with respect to laws and
regulations presently in effect. We assume no obligation to advise you of any
changes in law or regulation which may hereafter occur, whether the same are
retroactively or prospectively applied, or to update or supplement this letter
in any fashion to reflect any facts or circumstances which hereafter come to our
attention.

           Based upon, and subject to, the foregoing, we are of the opinion that
the Shares covered by Options outstanding as of the date hereof, when issued
upon proper exercise of the Options and payment of the exercise price, all in
accordance with the terms of the Plans, will be validly issued, fully paid and
nonassessable. The additional Shares covered by the Plans, when issued upon
proper exercise of Options to be granted by the Compensation Committee of the
Board of Directors or the Board of Directors and upon payment of the exercise
price, all in accordance with the terms of the Plans, will be validly issued,
fully paid and nonassessable.

           We hereby consent to the use of this opinion as an exhibit to the
Registration Statement and we further consent to the reference to our firm under
the caption "Named Experts and Counsel" in the Registration Statement and to any
reference to our firm in the Registration Statement as legal counsel who have
passed upon the legality of the securities offered thereby.

                                           Very truly yours,

                                           STRADLEY, RONON, STEVENS & YOUNG, LLP
