[TowerTalk] House Bracketing Rohn 25 or 45

[wd3q@erols.com (Eric Rosenberg)]

Two questions re: house bracketing, something I've never done.

I have a Force 12 C3SS, soon to be a C4SS, and am considering putting 
it up with their small WARC yagi.

1. If I house bracket a tower (Rohn 25 or 45),  how high can the tower 
and then the mast go above the roof line or top house bracket without 
guying, with one yagi or both?

2. Where in the NEC is there a discussion of proximity of power lines 
(the drop to my house) and the tower.

Thanks in advance,
