YDI WIRELESS AND PHAZAR MOVE FORWARD WITH MERGER

        FALLS CHURCH, VA and MINERAL WELLS, TX, October 4, 2004 – YDI Wireless, Inc. (Nasdaq:YDIW) and Phazar Corp (Nasdaq:ANTP) today provided a status report on their contemplated merger.

        Effective September 30, 2004, YDI and Phazar amended the merger agreement in a technical manner. For tax purposes, the merger was restructured to be a forward triangular merger with Phazar merging into the YDI merger subsidiary instead of a reverse triangular merger with the YDI merger subsidiary merging into Phazar. Phazar will still end up as a wholly-owned subsidiary of YDI, and Phazar stockholders will still receive 1.2 shares of YDI common stock for each share of Phazar common stock they own.

        Also, Phazar has received a second opinion as to the fairness, from a financial point of view, of the contemplated merger to the Phazar stockholders. The receipt of this second fairness opinion had been a condition to Phazar completing the transaction.

        As a result, YDI and Phazar are moving forward with the process to complete the merger and hope to have the merger completed by November 30, 2004.
