[Towertalk] Tutorial for Tower Raising/Guying?

[wd3q@erols.com (Eric Rosenberg)]

The roof tower I'm hoping to put up this summer will require 
guying.  While I've put up roof towers in the past, I've never had to 
deal with guying, its installation and other related issues.

I've gotten information from Phillystran on their product, but am 
wondering if there's a book, article or series of articles, or 
tutorials available that take one through the guying process... how and 
where to place them, installation tensioning, etc.

Any advice is appreciated!

Thanks and 73,
