YDI Wireless and Phazar Reaffirm Commitment to Merger

Falls Church, VA and Mineral Wells, TX — June 2, 2004: YDI Wireless, Inc. (OTCBB:YDIW) and Phazar Corp (NASDAQ:ANTP) today reaffirmed their commitment to their contemplated merger by signing an amendment to the merger agreement to address recent developments.

The recent amendment extended the time to complete the contemplated merger of the two companies. On April 1, 2004, the two companies extended the time within which the merger may be completed from April 1, 2004 to June 1, 2004. Effective today, the two companies have further extended that date to November 30, 2004. YDI recently purchased KarlNet, Inc. and entered into a definitive agreement to merge with Terabeam Corporation. Although Phazar approved of both of these transactions, they have been a factor in delaying the completion of the merger of YDI and Phazar.

In addition to the extension of time, the recent amendment provides that YDI will pay Phazar a $350,000 fee in the event that the merger of the two companies does not close by November 30, 2004 as a result of YDI making additional acquisitions or if additional delays occur as a result of YDI’s contemplated merger with Terabeam. Further, the amendment permits Phazar to withdraw from the merger agreement without payment of a termination fee if: (i) YDI’s pro forma balance sheet after consummation of the Terabeam transaction does not reflect a book value of at least $1.75 per share, (ii) YDI’s pro forma financials as filed with the Securities and Exchange Commission reflecting the Terabeam transaction do not reflect a book value of at least $1.75 per share, or (iii) the updated fairness opinion currently being obtained by Phazar reflects that the 1.2 exchange ratio following YDI’s merger with Terabeam is no longer fair to Phazar’s shareholders.

Robert Fitzgerald, YDI’s Chief Executive Officer, stated, “We are firmly committed to concluding our transaction with Phazar. While we would have liked this transaction to have been completed sooner, we believe the combined company will benefit from YDI’s transactions with KarlNet and Terabeam. The strategic reasons for the deal are as strong or stronger than ever. We appreciate the patience demonstrated by Phazar’s stockholders, board of directors, and will work diligently to conclude this transaction under the terms reflected in this recent amendment.”

Clark Wraight, Phazar’s Chief Financial Officer, stated, “We are very excited to be moving forward with the merger of YDI and Phazar. YDI’s transactions with KarlNet and Terabeam will add significantly to the capability and strength of the combined company. We are committed to completing this transaction and look forward to becoming part of YDI’s formidable team.”
