Re[2]: [TowerTalk] More questions Lighting protection

[Bob Otto]

Hello TT,

I'm also looking for information on grounding systems, and looked at
the Uni-Kit.   If you use conventional coax, do you still use the
Uni-kit?   Does it simply clamp around the coax, or do you have to cut
away the outer insulation to have it contact the braided ground?

Another question, is it better to use multistrand copper wire for your
ground wires from the tower legs rather than an equivilant size of
solid wire??   I plan to use #4 solid copper but saw some multistrand
at home depot the other day.  Would it be even better to take a piece
of 5/8" dia. copper water pipe and flatten it to use it as a copper
"strap"??  I looked at the copper straps from Polyphaser and they
seemed very expensive for thin copper material.  Am I missing
something?
