The T-Pass UHF transmitter multicoupler [e.g. 73-67-25-2C-03] from TX- RX systems uses cavity-ferrite technology and can combine two transmitters at a separation of only 75 KHz. "The loss ... is comparable to that of a hybrid combiner, but T-Pass provides the benefit of cavity selectivity for noise and intermodulation supression."
