I'm pretty certain you're going to be looking at something custom made. At qrp powers it might not be a problem to DIY a set of filters but with needing over 100dB of isolation between each band it sounds expensive.

Well, I do not actually need ports for 220 and 900 "currently". I have been looking at doing this for some time. My current plan is to use stacked or series du/diplexors for the bands I want to play (<30MHz, 50, 145, 430). Upper power limit is 500w pep which makes it a little easier. If I pass the power limit, there is not much question I must run separate feed lines. Adding 1296 and 2.4g also means separate lines. (The entry panel to the shack is beginning to resemble a cell tower entry panel since I have two towers fed from one panel. One tower is hf/terrestrial<30-1296 stuff. The other is satellite 144,432,1296,2.4g) _______________________________________________ Sent via AMSAT-BB@amsat.org. Opinions expressed are those of the author. Not an AMSAT-NA member?
