A long time ago I had a Rohn 25 tower with a Yagi on top turned
by a Ham-M rotor. I experienced severe TVI on channel 2. Somehow,
I don't know why, I got the idea that the bearings were rectifying.
I put a jumper loop of wire across the two halves of the Ham-M
and the TVI completely disappeared and never returned.

Hi,
I have discovered what it seems like rectification in my HD Alu Tower
where
on the top there is antenna ball bearing thrust (SKF) below a 61D
Prosistel
rotor. I used various techniques to pin poin to the tower.
