A wireless telephone server system used for reproducing a wireless base station signal and introducing the reproduced signal in a new geographical area. The system reproduces or clones a full, high power operating cell site or cell unit of the same electromagnetic magnitude at a reduced cost. The wireless telephone system includes a parabolic collector operating in a frequency range of 140 Mhz to 2 Ghz and with a magnitude inner gain in a range of 14 to 21 dBw. A server antenna is connected to the parabolic collector using matching feedline jumpers to produce a resonant match. The server antenna is designed to provide a “under and over” null to the main lobe of the antenna at a minimum of 40 dBw. The system includes a plurality of duplexing devices with a bi-directional amplifier which allows 124 dBw of isolation between the parabolic collector and server antenna. Also, the system includes low-noise amplifiers that are adjustable from 1 to 12 dBw in system gain. Further, the system includes either a mini-unit amplifier or a full-unit amplifier operating in a range of 40 to 140 watts. Each amplifier is designed not to allow any inter-modulation signal to develop to more than −68 dBw from the amplitude of the main carrier. The amplifiers insure interference free operation. The system also includes lightning arrestors, 50 ohm feedline jumpers and a weather-proof housing if required for storing the system therein.
