Hell, all.
I used to a lot or broadcast
work and it was sometimes quite an issue regarding the plants surrounding the
towers. One station was the olde KCBC in Des
Moines, IA on 1390 Kc., as it was
in those days. It was a 1 kw 4 tower array and being in Iowa it was surrounded on 3
or 4 sides with a cornfield. Enough said.
Another station was KHAK,
1350, 1 kw, 4 tower daytimes in Cedar
Rapids, about 130 miles east
and a bit north. You could look at the phase monitor and see it moving a few
degrees and the current varying. It started suddenly and I found the trouble
within a day: a field mouse nest in the de-coupling coil in the lighting system
for the NW tower.
Way back when a station in, I
think I was told, the town of Watertown, South Dakota installed a new station on the tallest point of a building. As the
engineer tuned the tower each nigh during testing all was excellent. On the
morning of sign on, with many dignitaries present the station was hard to keep
on the air – antenna problems. The reason: during business hours the
elevator shat house was where the antenna was installed and there was the
piston tuning and folk had the nerve to use the ‘vator.

I suspected I was getting
behind with the weeding (see attachment) - that explains the erratic antenna
current!
BTW - strong QRSS "Test"
signal from G3XIZ on 137.686 this morning
