[TowerTalk] TOWER GROUND

[Gary Schafer]

The copper when in contact with the galvanized tower will remove the 
galvanizing. A stainless sheet between copper and tower leg will work 
fine. Polyphaser makes some hose clamps with an additional stainless 
strap inside the clamp to accomplish this.

You also don't want any copper exposed anywhere that water dripping off 
the copper will drip or run onto any galvanized part of the tower. The 
copper ions will wash the galvanizing material away.
