Abstract
A repeater diversity system includes a null antenna having a given phase center and polarization for receiving a communications signal from a remote signal source, a donor antenna for transmitting a signal to a base station, and a diversity null antenna having the same phase center as the receive null antenna and a polarization orthogonal to the polarization of the main null antenna. A combining network is coupled to the main null antenna and the diversity null antenna for combining the signals therefrom and an uplink channel module is coupled with the combining network for delivering diversity combined receive signals to the donor antenna.
