1. A method of exchanging time division multiple access (TDMA) signals between a base station and a mobile TDMA handset, comprising the steps of:

  • supplying TDMA transmit signals from said base station through a signal conduit to a remote RF repeater;

    detecting the timing of said transmit signals at said RF repeater;

    broadcasting said transmit signals as radio signals from said RF repeater to said handset;

    broadcasting TDMA receive signals from said handset to said RF repeater;

    the timing of said receive signals being determined by said transmit signals at said handset;

    receiving said receive signals at a pair of spaced-apart antennas connected to said RF repeater to provide corresponding first and second receive signals at said RF repeater;

    employing the timing of said transmit signals to detect the signal levels of said first and second receive signals at said RF repeater;

    processing said detected signal levels of said first and second receive signals to provide a control output;

    employing said control output to alter the signal level of at least one of said first and second receive signals; and

    supplying at least one of said receive signals from said RF repeater to said base station.
