Why not modify the rotators, get rid of the strip and replace it with a 
sealing plate, Heyco (or similar cable clamp) feedthru clamp and a 3 or 4 
foot cable with a good wxproof connector. I use a 8 pin trailer connector. 
Did this to my HamM and TailTwisters. New rotators come this way now. Makes 
the guts wxproof and what I needed here on the OR beach. Simple fix.

Welll... Shucks! I was just getting ready to volunteer my tower as a
place to store the LDF-5.<:-))

I'm going to store a HAM-IV on it for one friend and it'll turn my C-19
XR while there. Unfortunately, or maybe fortunately, I discovered the
inside is full of sand....Well, not full, but there is plenty enough to
cause a short life. It's in everything. The bearings look like they were
rolled in it.  So I have to do a clean and grease, PLUS replace or fix
the broken terminal strip on the bottom which is where the sand got in.
OTOH the outside now looks like a new rotator of the proper gray color.
