Seen and done this before... Two Motorola T-1500 type duplexers, one setup on each repeater along with the proper tx circulator for each. The antenna port of both duplexers joined with another coax T... if you want to be really on the money use a n-way and remove the two duplexer output T's.
If the reflected power on the antennas is minimal the system should play just fine. I've seen it done at more than one commercial repeater site. The frequencies are far enough from each other that everything should play just fine. cheers, s. > Cort Buffington <[EMAIL PROTECTED]> wrote: > > Guys, > > I've found a site for my most recent Ham repeater project.
