MELVILLE, N.Y.--(BUSINESS WIRE)--March 16, 2000

Comtech Telecommunications Corp. (Nasdaq: CMTL) announced today that its Florida based subsidiary, Comtech Systems, Inc., has been awarded a contract valued at more that $10 million by a major U. S. corporation to provide a satellite communications network in the Amazon region of Brazil.

The Comtech network will be part of Brazil's countrywide surveillance and air traffic control system supplying data and voice traffic to and from remote areas.

Comtech Systems Inc. has the prime system responsibility to supply a hub satellite earth station and a number of fixed remote and transportable satellite earth terminals. Delivery is to begin in June 2000 and continue for approximately two years.

Comtech's Antenna Systems Inc., based in Florida, will supply 2.4-meter flyaway antennas for use by the system's transportable satellite earth terminals. Comtech Communications Corp. based in Arizona will provide redundant CSAT Transceivers and C-Band Up and Down Converters. As part of its execution of this project, as the systems contractor and integrator, the Comtech Systems operating unit will also supply a system-wide digital router network and a network monitoring and control system to monitor remote sites from the hub satellite earth station. Alcatel Brazil will provide field support services for the installation and acceptance testing in Brazil.

Fred Kornberg, President and Chief Executive Officer of Comtech Telecommunications, said Raytheon's selection of Comtech reflects Comtech's expanding acceptance in the satellite systems and equipment market.
