There is a reason why people post on usenet. They get answers.

And Steve, you have solved a years worth of puzzling and tweaking.
The SWR was the same with or without an antenna. The antenna
is bad. From the PL259 to the antenna I get no connectivity.
I just tested it with a VOM.

Why is it that the simple things are the last things you check.

Now does anyone know how to take a UHV-4 apart?

Thanks, Doc.

I don't have an antenna analyzer, so I can't check the resonant
freq that way. I was relying on an SWR meter (my shack one).
Nothing at all changes when I adjust the antenna. SWR doesn't
move. I may try to borrow an analyzer from someone to check
that out.

The mount and cable are fine. Just got a new 2m/70cm dual
band antenna to use until I can get the UHV-4 working.
It has a nice SWR of around 1.3 on 2m.

On the UHV-4 antenna, I can't get below an SWR on 2m of
around 5 or 6, even though it's supposed to be ground
independant (1/2 wavelength). I can't adjust the 2m/70cm
at all anyway. It's fixed.

Verify that the screw-off connector (NMO or 259) is actually
making contact... what you're describing (super high swr on
HF, high swr on 2m) points to a piece of unterminated coax
with no antenna on the end! Try reading swr without the UHV4
connected... same reading? Bad connection...
