[TowerTalk] questions about installing a mast

[Clay Autery]

If "I" were your code enforcement officer, I would prefer to see you use 
a properly engineered self-supporting tower over a properly engineered 
foundation vs. a push-up telescopic mast bolted to a chimney and guyed 
(sort of) to a residential roof.

But I am not your code guy... and have no idea what kind of bureaucracy 
you'd have to negotiate to get a tower approved without a 360 degree 
fall zone...

I wish you much fortune and luck in your pursuit!

73,

Given my lot layout, powerlines and neighbors, a tower or a guyed mast is not possible so I am considering an unguyed mast to serve as the centerpoint for a dipole. The mast would also host  2M/70CM and GMRS verticals, one under the other.

If I have to guy the mast, can I do so with two guy points on the roof, assuming I can get enough of an angle?  I am not sure how to figure this out, not having done it before.
