A frequency channel is assigned to each of a plurality of locations. A beam within the assigned channel and having a specified beam width is directed between a satellite and each location, and data is transmitted. A spread spectrum test signal is transmitted to the satellite, received, and processed, and a return test signal is transmitted from the satellite, and processed to determine the quality of operation of the antenna and associated electronics. A radio frequency signal having a first polarization is transmitted to the satellite, received, and processed to provide a first processed signal. The quality of the first processed signal is determined. If the quality is acceptable, the first processed signal is utilized. If the quality is not acceptable, the signal source is notified, and the radio frequency signal is retransmitted with a second polarization, received, processed, and utilized.
