I would look for 3 used sections of Rohn 25, then figure out how to safely
bracket it to your house, if possible. That should be do-able for somewhere
close to your budget and certainly capable of holding up a G5RV.

Well, it makes unassisted S/P a lot faster; just tune for the next blip.
And, if you have directional antennas, like a NE beverage on 160 or 80, it
helps to pre-qualify some signals as to multiplier possibility. And it
certainly helps to see how close the interference is when you're running. I
For the last 20 years, I have had a Joslyn 1265-85 at the panel. I'm sure
it's no longer available, but it's a 10x12x6 NEMA 4 box with fist-sized MOV
modules inside with some monitoring circuitry on a small pwb driving 2
front panel LEDs. I am at the very end of a long rural 12.4 kV run in

Now that you have a KAT-3, you have 2 antenna ports. Is there any chance
that the wrong one is selected for those bands?

It's 5/8-24, and not likely available at the hdwe store. For one thing, it
