Ok.....here is a question for everyone.
I recently acquired a few Decibel Products UHF bandpass cavities.
The model # of them are DB-4021. They are the same as the VHF
variety DB-4001, except these are the UHF version. The physical
size is the same as the VHF, and they have adjustable loops for
.5db to 3.0db.
My question is....Can I use 4 of these and make a UHF duplexer?
If so, what kind of isolation can I expect? Also, if so, should the
interconnecting cables be 1/4 wavelength at my frequencies and
should the cables to the tee at the antenna connector also be
1/4 wavelength each?
But, to throw another variable into the scenario......At the site where
I am, I pretty well can do as I please as far as antennas, cables, etc.
There is only one other UHF (commercial) system there. There is
already 2 UHF antennas and hardline that are not being used that
I can do with as I please.
Would it be better to use duplexers and 1 antenna, or maybe use
both antennas and put one of the pass cavities on my receiver
and one of the pass cavities on my transmitter?
All thoughts and advice are appreciated....
