hybrid and cavities, but in the real world,
you're talking very high Q cavities. The

would not play well at this close spacing.

Does anyone have a pair of VHF duplexers that are excess to their

anyone has a pair they can cut my club a good deal on {possibly

I am really glad to see the Tripler diagram put on the web. Do you you have the parts indentified by value somewhere?
Thanks

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,

Depends on what you call cheap.
I get some at Home Depot, and some at Ace hardware.
Should also be available at True Value, Lowes, and other building supply
and/or hardware stores.

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

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

You certainly can. As others have noted, the actual operating

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

It all depends on your frequencies,rx and tx.

Perhaps I wasn't clear. I have been using this simple comparison method for

with the 20 MHz WWV signal when it's strong enough.) What I was
