How big a hole can you get away with?
At AM, probably far larger than the box. (grin)

I wouldn't want to see anything larger than 1/50 wavelength hole in the
box. Still bigger than the box at mediumwave, even at the high end.
Thickness of the box also makes a difference when you are drilling holes
in it and affects the
Craig,
I guess I wont worry about it then. I still like the plug idea, to keep
the bugs out and spiders, earwigs, ants, would love to live in one of
the boxes, especially the spiders. No dangerous ones here, but still a
mess. They get into everything. Around here the outside of houses, cars,
etc
Rick,
I will have to use a bolt or plug in the hole and that should take care
of any issues. The trickness of the box varies. The cover has two screws
in it. It is just a conduit box that you would install a socket in a
house, but I covered it with a couple tricknesses of foil and then taped
it

Rick,
No pot in this box, just the F fitting and the two banana jax. The pot
is in the plastic termination box at the end of the antenna. I don't
think there is any issue there, as the wire from the pot fors directly
to the ground rod and the other wire goes directly from the end of the
EWE to

Yup, I wouldn't worry about plastic enclosures at the far end at all.

One thing that you could do, is to drill the holes in the bottom of the
box, thread them and put a bolt or screw into the holes and take them
out to drain the box and put them back in when done. You would have to
fiqure out how often to drain the box though. That would compremise the
box letting

Chuck,
OK, 1/10th of a wavelength. If I drilled a one inch hole in the box, it
would not make any difference. However, I do like the plug idea, as if
there is a hole it will be a nice home for bugs.
