    LAS VEGAS, April 23 /PRNewswire Interactive News Release/ -- Radyne
 ComStream (Nasdaq:   RADN) and Mentat(R) Inc. are jointly demonstrating a high
 performance solution for Internet over satellite at the NAB 2001 trade show.
 Radyne ComStream's IPSat and IPSat Plus Internet satellite terminals combined
 with Mentat's SkyX Gateway Internet over satellite performance enhancement
 system provides an ideal solution for high performance Internet access over
 satellite links.
     The Radyne ComStream IPSat Internet satellite terminal is an SCPC fully
 integrated modular system capable of receive-only, transmit-only, or full
 duplex satellite connectivity to the Internet anywhere in the world.  The
 IPSat Plus terminal is a bi-directional Internet Over Satellite system
 designed for bandwidth-on-demand Internet networks utilizing TDMA burst return
 channels.  In addition to the IPSat and IPSat Plus two way Internet over
 satellite capabilities, the modularity of the Terminals allows end users to
 take advantage of hybrid configurations in situations where terrestrial return
 resources are available to be used in conjunction with satellite broadcasting.
 The IPSat Terminals can offer the most flexible, cost-efficient performance
 for high-speed satellite downloads from the World Wide Web for ISP's,
 businesses, and individuals.
     The SkyX Gateway is a unique, patent-pending system for overcoming the
 limitations of Internet protocols when used over satellite networks.  By
 transparently replacing TCP with a highly efficient protocol especially
 designed for the long latency, asymmetric bandwidth, and high loss conditions
 typical of satellite networks, the SkyX Gateway makes possible terrestrial-
 like performance over satellite links.  The SkyX Gateway is ideal for
 enhancing the performance of both Internet and private network links and is
 entirely transparent to end clients and servers.
     "Mentat is pleased to partner with Radyne ComStream to jointly offer
 jointly a best-of-breed solution," says Kay Guyer, Mentat President.  "Radyne
 ComStream has been at the forefront of developing equipment and integrated
 systems for satellite networks which combined with our SkyX Gateway
 technology, offer a compelling solution for high performance Internet over
 satellite."
     "We have been working with Mentat and the SkyX Gateway on behalf of
 customers since last year and have been extremely impressed with the
 performance and quality of the Mentat product," says Brian Duggan, President
 and Chief Operating Officer of Radyne ComStream.  "The SkyX Gateway and IPSat
 together offer an unbeatable combination for any IP over satellite network."
     Demonstrations of the IPSat and SkyX Gateway will continue in the Radyne
 ComStream Booth # T1722
