Based on the philosophy of Anytime, Anywhere, and Anyplace, the amplifier module 806-869 MHz
is designed for ease of use and being adaptable to various needs in the field. Recently developed
technologies are applied and with the use of modern integrated circuits and RF components, the
Comprod design ensures constant performances and reliable amplifier unit.
Our 700 MHz amplifier has also been designed with government agencies in mind. These are our
highest level of performance and quality for continuous duty solutions while providing maximizing
coverage.
This amplifier module is aimed for the use in buildings, tunnel, government facilities, airports,
providing the communication throughout.
The amplifier module helps to increase the coverage of RF communications in buildings or places
where RF is unable to penetrate from the base station site. The Amplifier Module can be used in both
Uplink and Downlink directions and connected to either a radiant cable, a distributed antenna system
at one end. At the other end it’s connected to the donor antenna.
