          Re:  Sinclair Broadcast Group, Inc. Registration Statement on Form S-3

Dear Ladies and Gentlemen:

          We have acted as counsel to Sinclair Broadcast Group, Inc., a Maryland
corporation  (the  "Company"),  in connection with a Registration  Statement (as
amended, and including prospectus  supplements filed pursuant to Rule 424 of the
Securities Act of 1933, the "Registration Statement") on Form S-3 filed with the
Securities and Exchange  Commission (the "Commission")  under the Securities Act
of 1933, as amended.  The Registration  Statement relates to the registration of
the issuance by the Company of, among other things,  4,000,000 shares of Class A
Common  Stock of the  Company,  par value  $0.01 per share (the  "Class A Common
Stock"),  3,000,000 shares of $3.00 Series D Convertible  Exchangeable Preferred
Stock,  par value  $0.01  per share  (the  "Convertible  Exchangeable  Preferred
Shares"), and 6% Convertible  Subordinated Exchange Debentures due September 15,
2012 (the "Exchange  Debentures")  and the sale by certain Selling  Stockholders
identified  therein of up to 1,300,000  shares of Class A Common Stock (together
with the 4,000,000  shares of Class A Common Stock  offered by the Company,  the
"Class A Common  Shares").  The Class A Common Shares are to be sold pursuant to
an  Underwriting  Agreement (the "Common Stock  Underwriting  Agreement") by and
among the Company,  certain Selling Stockholders named therein, and Smith Barney
Inc.,  BT Alex.  Brown  Incorporated,  Credit  Suisse First Boston  Corporation,
Salomon   Brothers  Inc,  Chase   Securities  Inc.  and  Furman  Selz  LLC  (the
"Representatives"),  as  representative  of the  Underwriters.  The  Convertible
Exchangeable  Preferred  Shares  are  to be  sold  pursuant  to an  Underwriting
Agreement  (the  "Preferred  Stock  Underwriting  Agreement")  by and  among the
Company and the Representatives.

          For the  purposes  of this  opinion,  we have  examined  copies of the
following documents:

          1.   The Registration Statement;

          2.   The  Amended  and  Restated  Articles  of  Incorporation  of  the
               Company;

          3.   The Articles  Supplementary to the Amended and Restated  Articles
               of  Incorporation  of  the  Company   governing  the  Convertible
               Exchangeable Preferred Shares;

          4.   The form of the Subordinated  Indenture (the "Indenture") between
               the Company and the First Union  National  Bank,  as Trustee (the
               "Trustee");

          5.   The form of the First  Supplemental  Indenture (the "Supplemental
               Indenture") between the Company and the Trustee;

          6.   The Bylaws of the Company;

          7.   The Common Stock Underwriting Agreement;

          8.   The Preferred Stock Underwriting Agreement; and

          9.   The  Resolutions  of the Board of Directors of the Company  dated
               September 12, 1997.

          In our  examination  of the aforesaid  documents,  we have assumed the
legal capacity of all natural  persons,  the genuineness of all signatures,  the
completeness and authenticity of all documents submitted to us as originals, the
conformity to original documents of all documents  submitted to us as certified,
telecopied, photostatic or reproduced copies.

          This opinion is limited to the laws of the United  State,  the General
Corporation  Law of Maryland and New York  contract law (but not  including  any
statutes,  ordinances,  administrative  decisions,  rules or  regulations of any
political  subdivision  of the State of New York).  We are members of the Bar of
the State of Maryland and do not hold ourselves out as being experts in the laws
of any  other  jurisdiction.  Although  we do not  hold  ourselves  out as being
experts in the laws of any other  jurisdiction,  we have made such investigation
of the laws of the  State of New York as we  deemed  necessary  to  express  the
opinions set forth herein. Our opinion is rendered only with respect to the laws
and the rules, regulations and orders thereunder that are currently in effect.

          Based upon,  subject to, and limited by the  foregoing,  we are of the
opinion that:

          1. The Class A Common  Shares have been  lawfully and duly  authorized
and such Class A Common Shares, when issued and delivered in accordance with the
terms of the Common Stock Underwriting Agreement,  will be validly issued, fully
paid and nonassessable.

          2. The Convertible  Exchangeable  Preferred  Shares have been lawfully
and duly authorized and such Convertible  Exchangeable  Preferred  Shares,  when
issued  and  delivered  in  accordance  with the  terms of the  Preferred  Stock
Underwriting Agreement, will be validly issued, fully paid and nonassessable.

          3.  The  Company  has  the  legal  authority  to  issue  the  Exchange
Debentures that may be issued upon  conversion of the  Convertible  Exchangeable
Preferred  Shares and such  Exchange  Debentures,  when issued and  delivered in
accordance with the Indenture and the Supplemental Indenture, will, assuming due
authorization  prior to such issuance,  constitute valid and binding obligations
of the Company,  enforceable in accordance  with their terms,  except as (a) the
enforceability thereof may be limited by bankruptcy, insolvency, reorganization,
fraudulent  transfer,  moratorium or similar laws now or  hereinafter  in effect
relating to or affecting the enforcement of creditors'  rights generally and (b)
the availability of equitable remedies may be limited by equitable principles of
general  applicability  (regardless of whether considered in a proceeding at law
or in equity).

          We assume no  obligation to advise you of any changes in the foregoing
subsequent  to the  delivery of this  opinion.  This  opinion has been  prepared
solely for your use in  connection  with the filing of the Form 8-K on September
22, 1997 and  incorporation  by reference into the Registration  Statement,  and
should  not be quoted  in whole or in part or  otherwise  be  referred  to,  nor
otherwise be filed with or furnished to any governmental  agency or other person
or entity, without our express prior written consent.

          We hereby  consent to the filing of this  opinion as an exhibit to the
Form 8-K and  incorporation by reference into the Registration  Statement and to
the use of our name therein under the caption "Legal Matters."

                                       Sincerely,

                                       WILMER, CUTLER & PICKERING
