I'm curious if anyone has experience paralleling deep cycle batteries
for a repeater backup. I'm designing a battery disconnect circuit
that will open a relay if it detects over voltage, or if the
batteries discharge to a low voltage threshold. I'm also going to

Yes the repeater does work well with split antennas, no problems now
except for reduced TX coverage and a nice null towards the tower
opposite from the side mount..

That's why I pitch the cheap, plated bolts that come with the tower sections
and use stainless steel ones instead. The zinc plated ones would be rusty

If you go to buy gasoline and it's $2.579 per gallon, do you really think

We experienced a similar situation with an VHF repeater
two years ago. The culprit was traced down to rusty bolts
on the Rohn 25 tower. Tapping on the tower legs with a
large hammer would make the problem go away for a short
period of time, but it would return in a few weeks or days.

If it's a regular event in a light wind, I'd go after

The reactance back from the antenna might also contribute
