This Amendment No. 4 to Tender Offer Statement on Schedule TO (this “Amendment”) amends and supplements the Tender Offer Statement on Schedule TO originally filed on May 22, 2008 and amended on June 23, 2008, June 30, 2008, and July 14, 2008 (collectively, the “Schedule TO”) by Comtech TA Corp., a Delaware corporation (“Purchaser”), and Comtech Telecommunications Corp., a Delaware corporation (“Comtech”). This Amendment is being filed on behalf of Comtech and Purchaser.

The Schedule TO relates to the offer by Purchaser to purchase all issued and outstanding shares of common stock, par value $.001 per share (“Shares”), of Radyne Corporation, a Delaware corporation (“Radyne”), at a price of $11.50 per Share, net to the seller in cash, without interest thereon and less any required withholding taxes, upon the terms and subject to the conditions set forth in the Offer to Purchase, dated May 22, 2008 (as it may be amended or supplemented from time to time, the “Offer to Purchase”), and in the related Letter of Transmittal (as it may be amended or supplemented from time to time, the “Letter of Transmittal” and, together with the Offer to Purchase, the “Offer”), which are annexed to and filed with the Schedule TO as Exhibits (a)(1)(A) and (a)(1)(B), respectively.

Except as specifically set forth herein, this Amendment does not modify any of the information previously reported on the Schedule TO. Capitalized terms used but not defined herein shall have the meanings assigned to such terms in the Offer to Purchase.

As permitted by General Instruction F to Schedule TO, the information set forth in the Schedule TO, as amended by this Amendment, including all appendices, schedules, exhibits and annexes hereto and thereto, is hereby expressly incorporated by reference herein in response to Items 1 through 12 of the Schedule TO. You should read this Amendment together with the Schedule TO.

Items 1 through 9 and 11.

Items 1 through 9 and 11 of the Schedule TO, which incorporate by reference the information contained in the Offer, are hereby amended and supplemented as follows:

On August 1, 2008, Comtech announced that Purchaser successfully completed its tender offer to purchase all Shares of Radyne. The tender offer expired at 12:01 a.m., New York City time, on August 1, 2008.

According to the depositary for the offer, there were tendered and not withdrawn 17,360,213 Shares as of 12:01 a.m., New York City time, on August 1, 2008, and an additional 621,221 Shares were guaranteed to be delivered within the next three days.  These shares represent approximately 94.4% of the total outstanding Shares of Radyne.

The merger of Purchaser and Radyne was consummated effective as of 8:00 a.m., New York City time, on August 1, 2008 without a meeting of the stockholders of Radyne in accordance with Delaware's short-form merger statute. As a result of the merger, each remaining outstanding Share of Radyne was cancelled and converted into the right to receive $11.50 per Share, net to the seller in cash, without interest thereon and less any withholding taxes (other than any Shares held in the treasury of Radyne and each Share owned by Purchaser, Comtech or any direct or indirect wholly-owned subsidiary of Comtech or of Radyne or any shares held by Radyne stockholders that perfect their rights to appraisal in accordance with Delaware law).

The full text of the press release announcing the results of the Offer and the consummation of the merger is attached as Exhibit (a)(5)(E) hereto and is incorporated herein by reference.
