[TowerTalk] homemade beams

[Jim Idelson]

When you cut the coax to stuff in that tube, make sure you terminate the end to 
prevent arcing at high power. Water and other things that get inside the gamma 
rod will provide a path for RF to get to from the exposed center conductor to 
ground. This is a bad thing. I have climbed towers in the middle of the night 
during contests to fix this kind of problem. This also applies to the coax 
capacitors used in some trapped tribanders.
