1. A repeater diversity system comprising:

  • a main 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;

    a diversity null antenna having the same phase center as the main null antenna and a polarization orthogonal to the polarization of the main null antenna;

    a combining network coupled to the main null antenna and the diversity null antenna for combining received signals therefrom to constitute diversity combined receive signals, the combining network further configured to phase align the received signals; and

    an uplink channel module coupled with said combining network for delivering said diversity combined receive signals to said donor antenna.
