1. A transmitter diversity assembly for a communication station having a tunable transmitter operable to generate a communication signal of a plurality of frequencies, said transmitter diversity assembly comprising:

  • at least one dual-polarized antenna selectively connectable to receive the communication signal generated at the communication station, said at least one dual-polarized antenna for transducing the communication signal when applied thereto according to a selected polarization;

    a polarization selector coupled to the communication station, said polarization selector for selecting the polarization of said at least one dual-polarized antenna, the polarizations selected by said polarization selector selected to form a sequence of at least an alternating polarization; and

    a transmitter controller coupled to the communication station, said transmitter controller for causing the tunable transmitter to operate at a selected one of the plurality of frequencies and for causing the polarization selector to select one of the polarizations forming the sequence of the at least an alternating polarization;

    wherein the communication signal transduced by said at least one dual-polarized antenna has both frequency diversity and polarization diversity.
