Comtech Telecommunications Corp. Receives Orders Totaling $3.0 Million to Supply Additional AN/TRC-170 Modem Upgrade Kits and Extended Warranty Coverage to the U.S. Army

MELVILLE, N.Y., Apr 11, 2007 (BUSINESS WIRE) — Comtech Telecommunications Corp. (Nasdaq: CMTL) announced today that its Orlando, Florida-based subsidiary, Comtech Systems, Inc., has received orders aggregating $3.0 million for additional AN/TRC-170 modem upgrade kits and extended warranty coverage for previously purchased upgrade kits from a major U.S. contractor under the U.S. Army Common Hardware Software-3 (CHS-3) Contract.

These additional state-of-the-art modem upgrade kits will be used by the U.S. Army to upgrade its AN/TRC-170 troposcatter terminals to 16 MB/s and include Comtech’s patented Turbo Product Code forward error correction technology. In addition to providing the highest level of proven performance achieved on troposcatter links to date, the modems also include automatic power control, which allows for lower transmitted power when communication channel conditions permit, reducing the risk of unfriendly intercept and interference with other communications. Operators can select data rates from 2 MB/s to 16 MB/s from the front panel of the modem. The increased capability of the upgraded AN/TRC-170 terminals reduces the dependence on satellite communications in areas of conflict.

Recent field exercises using the AN/TRC-170s upgraded with Comtech Systems’ advanced troposcatter modems have shown data throughputs and quality of service never before achieved in the AN/TRC-170.

Fred Kornberg, President and Chief Executive Officer of Comtech Telecommunications Corp., said, “We are extremely pleased by this award from the U.S. Army for additional modem upgrade kits. Once again our industry-leading and field-proven troposcatter modem technology was the key to success in receiving this award.”
