[TowerTalk] guying distance

[Grant Saviers]

An AM radio tower only has to support the tower and its wind load.

I think marketing comes into play for the 80%.  ie what practical length 
guy base, #, and placement maximizes the tower antenna sq ft load 
rating.   If I were Tim Rohn that is what I would ask the engineers to 
specify for the amateur community.
