Subject: [TowerTalk] Grounding connection to tower legs
<What?s the best way to connect the copper wire/strap to the 55G tower leg?
I?m planning to clean the galvanized leg, wrap the leg with a layer of 0.005?
SS shim stock and then use a couple of SS hose clamps to hold the wire against
the tower leg.
Is that the right way to do the attachment?
Should I use any copper paste as well?

## What does Rohn have in its catalog ?? They must have the correct
compression assy for 55-G legs. I used 2 gauge stranded copper wire,
insulated, like RW-90.
One end to cadwelded ground rod, with cadweld and top of ground rod a few
inched below the ground. Other end goes to compression lug fitting.
Correct die used to compress
the lug onto the 2 gauge stranded cu. Hole in compression lug bolted to
tower base. But that part depends on what type of tower it is. For
something like 55-G legs, it should
consist of a 2 x piece clamshell with a big enough flange to handle the mating
compression lug assy. Use thin layer of penetrox goop on the leg, and where
the mating flange +
compression fitting bolt together. SS + cu is bad news. So is SS and
galvanized surfaces.
