Folks,
Thanks for the input, but changing the configuration of the commercial
repeater is not an option. I'll probably do a little tinkering, then
end up putting up a separate antenna for my repeater below the other
one. My reason for doing this is that it would have avoided me buying
When I talk combiner, think duplexer on steriods..
Do a google search on hybrid combiner..
A combiner with give you several rx and tx ports..

Isolators work with transmitters only. That would do nothing for
getting signal from the antenna into the repeaters.
What you need is a diplexer. That is a low pass / high pass filter
network. These can be constructed with L/C high pass and low pass
filters, but that usually only has enough Q to
BpBr duplexers only do wonders for the frequencies of intrest. That is the
TX and RX frequencies. The space in between the 2 is somewhat attenuated,
but the space outside the 2 frequencies is attenuated only -6 to -20dB
depending on the frequency spacing, number of cavities and who made the
If the duplexers for each system are only 50 ohms at each receiver and
transmitter, then I should see 4 frequencies where there is a 50 ohm
load, and they are all different. Why would I need more than some sort
of phasing harness to connect the two duplexers to the single
transmission
I stand corrected!

Subject: Re: [Repeater-Builder] Re: Two Repeaters, One Antenna
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
Just what do you mean by an N-Way instead of the T connector, Never heard
of this.

Unless you want to spend time with the proper test equipment, it
is probably a lot more prudent to make all the cavities in your
mini antenna system the same or very similar types.
The stacked T-1500 duplexer layout I describe has the antenna
ports joined with another T... while this works
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
Good question...
So what do you call a T-Connector with more than 3 ends on it?
A T Connector with 4 coax ports/ends on it is called a 4-Way
... or 4 Way Star.
The N in N-Way is the number of available coax ports.
Using the word star as a description can be tricky to those
who think

Two antennas on one mast, less insertion loss, with combining the 2
duplexers.
Or make the top antenna a Master receive and the bottom one transmit
combined.
