COMTECH TELECOMMUNICATIONS CORP. ANNOUNCES

RESULTS FOR THE FIRST QUARTER OF FISCAL 2007

Melville, New York – December 4, 2006 – Comtech Telecommunications Corp. (NASDAQ: CMTL) today reported its operating results for the three months ended October 31, 2006. Net sales for the first quarter of fiscal 2007 were $97.1 million compared to $106.6 million in the first quarter of fiscal 2006, reflecting growth in the telecommunications transmission segment offset by lower sales, as anticipated, in the mobile data communications and RF microwave amplifiers segments.

GAAP net income was $10.8 million, or $0.41 per diluted share, for the three months ended October 31, 2006 compared to $11.5 million, or $0.43 per diluted share, for the three months ended October 31, 2005. Non-GAAP net income, which excludes the amortization of stock-based compensation expense, was $12.1 million, or $0.45 per diluted share, for the three months ended October 31, 2006 as compared to Non-GAAP net income of $12.5 million, or $0.47 per diluted share, for the three months ended October 31, 2005.

In commenting on the Company’s performance during the first quarter of fiscal 2007, Fred Kornberg, President and Chief Executive Officer of Comtech Telecommunications Corp., said, “We are very pleased with our first quarter results which are expected to serve as the foundation for another record year in fiscal 2007 on our top and bottom lines.”

Mr. Kornberg added, “Average quarterly sales for the Company are expected to increase for the remainder of fiscal 2007 as a result of our anticipated ongoing support of Movement Tracking System program activities and as deliveries occur on recently received orders, including our contract to upgrade the U.S. D.o.D.’s AN/TRC-170 digital troposcatter terminals.”

Selected First Quarter Fiscal 2007 Financial Metrics and Other Items

• Bookings for the first quarter of fiscal 2007 were $121.4 million compared to $110.1 million in the first quarter of fiscal 2006. Backlog as of October 31, 2006 was a record $210.4 million compared to $186.0 million as of July 31, 2006.

• Earnings before interest, taxes, depreciation and amortization (EBITDA) were $19.2 million and $20.1 million for the three months ended October 31, 2006 and 2005, respectively.

• Cash used in operating activities for the first quarter of fiscal 2007 was $3.6 million compared to cash provided by operating activities of $7.2 million for the first quarter of fiscal 2006, reflecting a significant increase in inventory that is currently anticipated to be delivered to our customers (primarily the U.S. government) throughout fiscal 2007, as well as the timing of payments for accounts payable and certain accrued expenses that occurred in the first quarter of fiscal 2007.

• Fiscal 2007 first quarter net sales and gross profit were favorably impacted by $1.2 million and $1.1 million, respectively, due to a gross profit adjustment to the MTS contract in our mobile data communications segment. The adjustment is more fully described in our Form 10-Q filed earlier today.

• The Company completed the acquisition of certain assets and assumption of certain liabilities of Insite Consulting, Inc. (“Insite”) and the consolidation of Comtech Tolt Technologies, Inc. (“Tolt”). Sales relating to Insite’s geoOps™ Enterprise Location Monitoring software and Tolt’s turnkey employee mobility solution products were insignificant during the first quarter of fiscal 2007.

• As disclosed in our Form 10-Q filed earlier today, the Company has added a risk factor relating to a notification it received from the Company’s auditors, KPMG LLP, concerning KPMG’s independence with respect to the Company.
