Yes there is... but it's really big even for UHF. Phelps Dodge Made
one and I've seen a number of odd ball units around with Harris labels
on them. Normally the smaller mobile duplexer are notch-pass (aka
notch-notch). But everything is possible... and probably tried at
least once.

Band Pass. No caps on it for notch tuning as on celwave. Am I missing
something here?

Don't! Scott is talking about a notch type duplexer, not a pass band one.

---As Skipp pointed out, most the so-called mobile duplexers are
notch only. You have a make and model #?
Are you sure it's not a notch type duplexer? It takes large cavities for a
bandpass duplexer unless the spacing is quite wide.

Lots of the small mobile duplexers (notch type) have fixed capacitors inside
and you can only adjust the cavity tuning, which tunes the notch.
This type duplexer is limited in how far from the design frequency you can
tune it as the capacitors are fixed. The cavities will tune but the loss
goes.

Hi Jed.
If you're not interested in a lot of gain, try a discone. They're about as
broadbanded as you can get, and not too expensive. I bought one from the

up. I've seen some discones designed for scanners that
it's also not a stacked so bear little relevence to the matter
Trying to understand what stacked has to do with the discussion...
There is little or no
automatic penalty for using a non-resonant antenna.
just some efficiency

If I understand it correctly, the discone is nothing more than a ground
