The transceivers for each Band are connected to their associated pass filter, and then multiplex device such as a triplexes, which is Teri-Band beam, example. Connector clearance will add even more. All transceivers can operate simultaneously with up to 80 db of isolation, unhindered by the signals from other connected radios operating on Bands same antenna. 5 MHz and just above 4.
This is because the multiplexers main purpose to balance impedance's for multiple-transceiver single multi-Band antenna stations. Depth in: 7. They provide uhf female so-239 connections for multiple 50-ohm transceivers to be connected a single feed line.
