1. A method of retransmitting, via an antenna, a plurality of electro-magnetic signals in a radio telephone system wherein the signals originate at one or more sources, the method comprising:

  • establishing a plurality of retransmitting communications channels;

    detecting one or more received electro-magnetic signals from a first orientation relative to a respective source;

    detecting the one or more received electro-magnetic signals form a second orientation relative to the source;

    selecting as an input to each of the retransmitting communications channels one of the electro-magnetic signals detected from one of the orientations;

    determining a value of a selected parameter of the selected input to each of the communications channels from said selected orientation;

    determining independently for each channel if the electro-magnetic signal being retransmitted should be detected from the other orientation by comparing said value of said parameter to a selected value corresponding to one of a running average of previously determined parameter values associated with said selected orientation or a predetermined threshold value and radiating via the antenna the electro-magnetic signals form the retransmitting communications channels.
