PRESS RELEASE

Radyne ComStream Announces its Intent to Make a
$1.55 per Share Cash Tender Offer for Wegener Corporation

PHOENIX, AZ - April 21, 2003 — Radyne ComStream Inc. (Nasdaq: RADN; Warrants: RADNW), today announced its intent to make a cash tender offer for all of the outstanding shares of common stock of Wegener Corporation (Nasdaq: WGNR) for $1.55 per share. The offer price represents over a 70% premium to the value of Wegener’s average closing stock price during the past 30 trading days. Depending upon the number of shares purchased by Radyne ComStream, following completion of the tender offer, Radyne ComStream intends to consummate a second-step merger in which all remaining Wegener stockholders would receive the same cash price paid in the tender offer.

Based on the latest publicly available information, Wegener has approximately 12.3 million shares outstanding on a fully diluted basis, which would give Radyne ComStream’s proposal a total equity value of approximately $19.1 million. The acquisition is expected to be accretive to Radyne ComStream’s earnings per share.

Bob Fitting, CEO of Radyne ComStream, said, “We have been forced to take our offer directly to Wegener stockholders after continued refusals by Wegener to consider seriously Radyne ComStream’s offer to acquire the company. We believe that the stockholders should have the option to choose a transaction providing them with the greatest value.”

On April 1, 2003, Radyne ComStream made an offer to the Wegener board of directors to acquire through a merger all the outstanding shares of Wegener for $1.55 per share in cash. The merger offer was ignored by the Wegener board.

Snell & Wilmer LLP is acting as legal counsel to Radyne ComStream.

About the Tender Offer

Once the tender offer is commenced, offering materials will be mailed to Wegener stockholders and Radyne Comstream will file all necessary information with the United States Securities and Exchange Commission. Under applicable law, Wegener is required to file with the SEC a statement as to its position on the offer as well as other required information within 10 business days of the date on which the offer is commenced.
