FOR IMMEDIATE RELEASE
- ---------------------
June 2, 2004

                             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
management and believe this reflects their continuing belief in the soundness of
our deal. We 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."

companies' industries and resulting impacts on their pricing, gross margins, and
general financial performance; difficulties in predicting the combined company's
future financial performance; and risks arising from and relating to YDI's
