have been using TX RX for years on a number of tower sites.

combiner for ~8k.

We use many ham and commercial repeaters using the same antennas, but
require the proper filtering. A mobile duplexer is not sutable for what you are
trying to do here. You can get a transmit combiner Hybrid or cavity for the
transmitters and use a receiver multicoupler that has a dual window one for the
ham receive and one for the commercial receive or use a cavity combiner for the
receiver. That was is my preferred method, more isolation but costs much more.

I have a very broad band uhf antenna on a tower . I would like to run a
440 MHz machine and a 462 MHz machine off of the same antenna . Can I
use a notch type mobile duplexer to combine the 2 machines to 1 ant for
both TX and RX to notch the respective TX freqs after the duplexers
that are on the 2 machines .
