I have a 64' self-standing tower with a 3 el Steppir on it (insulated

I've worried that any high voltage on the ends of the boom might be harmful
to the drive motors in the dir/ref boxes.
So I've chickened out and avoided loading the tower on 160.
I have a 3-el SteppIR on a 120 ft tower. I don't load the tower, but the
tower is a reflector for a wire that is suspended from it, insulated
from it, and slopes to a point on the ground about 50 ft from the tower
where it is fed against four elevated radials (about 18 ft). This makes
the top of the tower a high voltage point, although probably not as high
as it would be if I were loading it). There are two antennas rigged like
this, one facing the east coast and one facing west. I've been using
them for about three years, mostly running legal limit, and the SteppIR
still works fine.
