When the 2 channels are around 2 to 2.5 mhz
apart it is pretty easy to use 2 duplexers, BpBr tuned to pass normally, but
the reject is set normal on one cavity, and to reject the second repeater tx,
or rx on the second cavity.
If the two channels are 200 khz or less
apart then a singl

Hey there
I don't know why I skipped this idea but slow waking up today, I just
mounted one of these nick named a half-n-half about a week ago. If
mounting only one antenna is your limitation this method has solved the
problem more than once, db products can do the stacking and it ends up
being about 16 feet

Not necessarily. You can combine the combiner and multicoupler on one
antenna, but it's even mor
Jed,
There are several options, all of them expensive. Whether you go the
hybrid-ferrite route or the cavity-ferrite route depends not only upon
the frequencies of your two repeaters, but also those of other
transmitters at the site. Either way, you must separate the two
receivers from the two t

It all depends on your frequencies,rx and

You would need a combiner/multicoupler combination. I think it's been
done, but it's very expensive. Typical combiner/multicoupler use is to
have one each on its own antenna - one on the combiner for the TXs, and
another on the multicoupler for the RXs. This is expensive on its own.

Typically no, the transmit part is the combiner and it will be expensive
unless you get very lucky in used stuff. All the filtering/duplex parts
will be very frequency specific and tough to locate already in the ham
band, you may find the losses far outweigh choosing another site. Have

I have 1 sight, and 2 repeaters.
We don't have the space to put them on separate
antennas.
We have a station master.
Could i run 2 UHF repeaters on 1
antenna?
I know i would need a combiner. What type of
combiner would
