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 clones a full, high power operating cell site of the same electromagnetic magnitude at a reduced cost. The wireless telephone system includes a parabolic collector (20) 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 (22) is designed to provide an "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 (28, 34, 40, 48) with a bi-directional amplifier (38) which allows 124 dBw of isolation between the parabolic collector (20) and the server antenna (22). Also, the system includes low-noise amplifiers (32, 66) that are adjustable. Further, the system includes either a mini-unit amplifier or a full-unit amplifier (44) operating in a range of 40 to 140 watts.
