What you want to do has been done before. I believe the documents in the link below has information on this. I used to have a big foldout document from moto on the 1500 duplexers and it showed a configuration you describe. I hope the PDF documents on this like are the same I am thinking of.

Nice farm tower on a hill, clean of RF colo, etc. The farm repeater is a 463.xxx + machine and I'm on 444.825. It is set up with nice hardline and a 16 bay folded dipole antenna (not sure the mfg., but he thinks it's DB). Anyway, assuming that thing has useable SWR on my TX frequency (I've had that happen before, not holding my breath), does anyone have any ideas about the viability of running both repeaters on the same antenna but connecting the duplexer outputs together in to the common feedline? I've done no math, and not a lot of thinking, but is this one of those times when I might run odd multiples of 1/4 wave coax to a T at the hardline or something? Both repeaters have BpBr duplexers and both have isolators on their outputs. 73 DE N0MJS -- Cort Buffington H: +1-785-838-3034 M: +1-785-865-7206 Yahoo! Groups Links
