T-1500 type is what's in the commercial repeater (micor). My repeater
has a Wacom WP-678-R2 on it.
Odd multiples of 1/4 coax between duplexer tees and the antenna tee?
BTW: A big thanks to Skipp, Phil and the rest who've jumped in here
today. I sometimes get some crazy notions (ham guy, not commercial 2-
way shop here) and I really appreciate this group. I lurk a lot and
learn a lot -- only hope I can give back more someday.

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.
