Com radios connected to the same antenna must have a "transmit" activated switch (relay) to shut off the antenna feed to the non-transmitting radio so the 5 or 10 watts of power sent by the transmitter doesn't blow up the other receiver. This type of di-plexer is expensive, but not as expensive as the repair work to a burnt up radio.
