The satellite signals travel along a satellite signal route encompassed within an aperture of the satellite receiving antenna. A terrestrial transmitter transmits signals at the first frequency along a wireless transmission route from the transmitter to the user location. The terrestrial transmitter is located with respect to the user location so that the wireless transmission route is outside of the aperture of the satellite receiving antenna. Also the terrestrial transmission power is controlled so that the terrestrial signals present at the user location result in terrestrial input signals from the satellite receiving antenna which are below an interference signal power level with respect to satellite input signals produced by the satellite receiving antenna. Thus, the terrestrial signals do not interfere with the satellite signals even though they are transmitted at a common frequency. However, the terrestrial signals are maintained at a power level at the user location such that information may be extracted from terrestrial signals.
