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  Registration  Statements (as
amended, and including prospectus  supplements filed pursuant to Rule 424 of the
Securities Act of 1933, the  "Registration  Statements")  on Form S 3 filed with
the Securities and Exchange  Commission (the "Commission")  under the Securities
Act of 1933, as amended. The Registration  Statements relate to the registration
of the  issuance by the Company of  6,000,000  shares of Class A Common Stock of
the Company, par value $0.01 per share (the "Class A Common Stock") and the sale
by certain Selling Stockholders  identified therein of up to 2,030,187 shares of
Class A Common Stock (together with the 6,000,000 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 Salomon  Smith Barney,  Smith Barney Inc.,  BT Alex.  Brown
Incorporated,  Credit Suisse First Boston Corporation, Bear, Stearns & Co. Inc.,
Furman Selz LLC,  Goldman,  Sachs & Co.,  Lehman  Brothers Inc. and  NationsBanc
Montgomery  Securities LLC (the  "Representatives"),  as  representatives of the
Underwriters.

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

1.       The Registration Statements;

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

The Bylaws of the Company;

4.       The Common Stock Underwriting Agreement;

5.       The Resolutions of the Board of Directors of the Company dated April 7,
         1998.

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  States  and the  General
Corporation Law of Maryland.  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.  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
(i) the Class A Common Shares have been lawfully and duly  authorized,  (ii) the
Class A Common  Shares to be sold by the Company,  when issued and  delivered in
accordance with the terms of the Common Stock  Underwriting  Agreement,  will be
validly issued,  fully paid and nonassessable,  and (iii) assuming conversion of
Series B Preferred  Stock held by the Selling  Stockholders  into Class A Common
Stock pursuant to the terms of the Amended and Restated Articles of the Company,
the Class A Common Shares to be sold by the Selling Stockholders will be validly
issued, fully paid and non-assessable.

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 April 10, 1998 (the "Form
8-K") and  incorporation  by reference  into the  Registration  Statements,  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,
/s/THOMAS & LIBOWITZ, P.A.
