The UHF X-POL switch has been designed to be used with two 435MHz yagi antennas mounted in a X configuration for use with the LEO Satellites. The switch allows the antennas to be switched between Vertical, Horizontal, Right Hand Circular and Left Hand Circular Polarization.  Depending on the bandwidth of the antennas used, the switch will work between 430 and 440MHz for both terrestrial horizontal SSB, and vertical FM Polarization.
