- Digital Over-the-Horizon System for Communications Between

Off-Shore Oil Platforms -

- Part of Refurbishment/Replacement of Existing System -

Comtech Telecommunications Corp. (Nasdaq:CMTL) announced today the award to its Florida subsidiary, Comtech Systems, Inc. of a contract valued at approximately $1,400,000 from a Southeast Asian subsidiary of a multi-billion dollar global conglomerate, for a digital over-the-horizon microwave communication system. Under this contract, Comtech will design and replace the existing communication system between the customer's on-shore facilities and two (2) off-shore oil pumping and collection platforms. The Comtech system will be used to carry both voice and data traffic of up to 8 megabits.

This Southeast Asian oil company chose Comtech Systems to supply the digital over-the-horizon communications system because Comtech is a leading supplier of field proven digital equipment and has proven experience in providing advanced specification compliant digital systems on time. Due to the difficulty of the transmission link, Comtech's DTR Series 91 Digital Radio, it's patented adaptive S-575 Digital Tropo Modem will be used in conjunction with its latest power control and performance monitoring equipment. The power control and performance monitoring equipment provides automatic adaptive control which reduces the possibility of frequency interference in high density frequency congested areas.

Fred Kornberg, President and Chief Executive Officer of Comtech Telecommunications, said Comtech is the only U. S. company capable of supplying the digital equipment called for under the contract which requires operation at 8 megabits.

"Our success in winning this replacement contract is fresh evidence of Comtech's leadership in the over-the-horizon microwave telecommunications field," Mr. Kornberg said. "We are in an excellent position to get more business of this kind as other aging telecommunications systems around the world require refurbishment and replacement."

Comtech Systems, Inc., an Orlando, Florida based company, specializes in system design, integration, supply and commissioning of turnkey communication systems including troposcatter, satellite, and line of site microwave systems.

Comtech Telecommunications Corp. is an innovative player in domestic and global high-technology markets.
