Doc it works great but it is expensive compared to clamps. You have to get
the surfaces really clean and follow instructions carefully - but if you do
the results are very good. I went with the compression clamps and lots of
cleaning kits and goop before putting them together. If your major purpose
is lightning protection, I think the clamps are okay. If you are trying to
generate the perfect pattern, or you are a broadcast engineer in a marginal
"proof of performance" situation, or are just borderline OCD like many of
us, then go with the CADWELD.

Subject: [TowerTalk] Exothermic Welding?
I am getting ready to install some ground rods for the tower.
The PolyPhaser literature and, I believe, the NFPA literature talks
about welding the ground wire to the rods with "exothermic welding."
It sounds a little like witchcraft starting with some aluminum oxide
powder and copper powder and an ignition powder with a form to put it
all in.
Anybody acquainted with exothermic welding?
Doc, N9AM
