ABSTRACT:
The present invention discloses a system and method by which radio transceiver equipment may be coupled to antenna equipment polarized in either of two orthogonal polarizations without requiring any adaptation or additional componentry while providing the same signal path attributes irrespective of the polarization chosen. Accordingly, a single transceiver/antenna unit may be utilized for providing communications polarized vertically, or slant right, and polarized horizontally, or slant left.
