Anecdotal evidence is tough... but I once heard of a 2m legal limit amp that burned out an N connector. There are lots of unknowns though, especially since this was on a field setup for a contest. co

I would hate to do the rebar for it. A 25' long rebar cage that has to be positioned in the middle of the hole and have clearance to the sides all around. and pouring would be a problem also, free fa

Porcupines can be a real pain. One of the local cable company engineers told me that he had to throw pieces of hardline at the base of poles through the woods from his head end site to keep them from

It does if you tie a big loop in it so that the knot can be pulled back to the boom-mast plate to be untied. I have been using that for years and it works great. David Robbins K1TTT e-mail: mailto:k1
There is actually a whole cd out there of ham songs: Seek You (Amateur Radio Songs) by of all things "The Ham Band" It includes songs like "Always on the Air" "I'm not climbing up the tower any more"
I like a relatively short top boot, maybe 6" high. The important part is that it must have a steel shank and thick non-slip sole. A good notch between the heel and ball helps to stand on rungs better
