Trying to find a solution for my setup to combine several antennas into one line to feed multiple receivers (trying not to have a bunch of LMR400 lines). I have three white stick antennas (162, 850, & 978/1090MHz) plus a discone (general ~450MHZ) that I want to feed into a single LMR400 cable down to a multi coupler. Of course, there are no commercial tri/quadplexers that will achieve this and I have several receivers that will need to pull in multiple frequencies, so individual coax lines aren't the best solution.
Anyway, my question is would adding individual notch filters to the inputs of a splitter/combiner achieve the same isolation and low insertion loss that an off the shelf triplexer would achieve? Trying not to get overly complicated here, but with my limited knowledge on RF behavior, I'm just not sure. Thoughts??
