ABSTRACT:
A scanning and targeting system (100) interconnects a plurality of radio channel units (203) in a single trunk group with a plurality of antennas (202), each radio channel unit (203) having a receive section and a transmit section and the scanning and targeting system dynamically connecting the receive section of each one of the radio channel units with any one of the plurality of antennas which, on average during a sampling period, has the strongest received signal strength of RF signals at the operating frequency of the radio channel unit, and the scanning and targeting system dynamically interconnecting the transmit section of each of the plurality of radio channel units with any one of the plurality of antennas which, on average during the sampling period, is best suited for transmitting RF signals at the operating frequency of the radio channel unit in a direction corresponding to the desired destination for the transmitted RF signals.
