[TowerTalk] Fwd: Grounding connection to tower legs

[Steve Maki]

Commercial tower grounds are almost always cad-welded, but usually to 
the heavy base flange(s), or to heavy tabs already welded to the tower 
expressly for the purpose of grounding.

I've seen some cad-welds on *solid* legs, but I can't recall any on pipe 
legs.
