FIELD: cellular radio communication systems; microwave communication systems. SUBSTANCE: proposed system has subscriber station, duplex antenna amplifier, and antenna. Subscriber substation has controller, transmitter, receiver, two filters, controlled power supply, and low-frequency filter. Duplex antenna amplifier has two low- frequency filters, controlled power supply, two amplifiers, and stabilizer; first alternative is characterized in that it has four filters and second alternative is distinguished by introduction of splitter, rejection filter, and duplex filter. EFFECT: improved economic efficiency at full correction of transmitter and receiver signal decay in communication cable. 2 cl, 6 dwg
