Dear TT Colleagues,
There has been so much discussion here about dealing with lightning
protection and grounding systems that I can't remember whether I read about the
following topic or not.
I'm planning a ground radial system for each tower leg (yes, a peripheral
ground system and single point ground, etc too) and have decided to use a heavy
braided tinned copper cable as the radial for each of these legs. I have just
about ruled out copper ribbon for various reasons. Ground rods will be 6' or 8'
deep set on 12' or 16' centers.
Question is: Cadwelding is VERY EXPENSIVE when used to attach the radials to
the ground rods! Can anyone comment on whether there will be sufficient
bonding and heat protection if a heavy silver solder bond is made in place of
the cadweld. I realize that cadwelding forms a molecular bond but it's just so
