Not quite; a duplexer is typically used where you want to TX and RX
simultaneously on quite close frequencies like in a repeater, and a
diplexer is more commonly used
Since we are beating this horse.
Does anyone have any pointers to units that allow more than three inputs
or outputs or commercial higher power units? I want to run HF through
2.4g down a single hardline and breakout each band at both ends. This
would be used instead of a remote antenna switch.
Dear Friends,
Perhaps this will help clear up the confusion.
A diplexor is a passive device that lets you split
and/or combine signals based on their frequencies.
It does not matter whether the frequencies are close
together or on different bands nor does it matter if
you are using it for
Well, I do not actually need ports for 220 and 900 currently. I have
been looking at doing this for some time.
My current plan is to use stacked or series du/diplexors for the bands I
want to play (30MHz, 50, 145, 430). Upper power limit is 500w pep which
makes it a little easier. If I pass the
I'm pretty certain you're going to be looking at something custom made.
At qrp powers it might not be a problem to DIY a set of filters but with
needing over 100dB of isolation between each
band it sounds expensive.

Yes Nigil, I need a spell checker on my email.

Mike,
I have used such a setup for some time now, I have a 2m/70cm diplexer at
my desk and one at the antennas, so that I can use one feed line
(LMR-600). I also switch the heck out of the feeds with several coax
relays in order to achieve different satellite modes as well as put the

Bob,
You shouldn't need either if you plan on using a dual-band antenna.
However, You'll get good uplink, but your downlink will likely suffer.
Then's when you want to use a Diplexer to split your receive signal out so
that you could put a preamp in line or even better, a beam antenna and
