Good point, though being so close I can get away with just
doing things to suspect cables, as it's bound to help.

Because I can't properly insulate the base of the roof tower &
it's counterpoise can move around, the situation changes &
Sod's Law has it I have to find something to work when I
QSY to 80 in the middle of a contest, so in a way the trial &
error way has its advantages for me.
