[TowerTalk] Heights aluminum tower

[DF3KV]

Adding guys to a self supporting tower generally raises the allowable wind
load and don´t make it fail.

If the force of wind blows across guys would be transferred as downward
force through the tower to the base, then guy anchors would be a piece of
cake.
IMHO only the pre tension force and weight of the guys will add to downward
force to the base.

The thing that makes a self supporting tower self supporting is the big 
block of rebar reinforced concrete under it. Adding guys to a self 
supporting tower may actually make it fail because of loads introduced 
by the guys that were never intended by the manufacturer.

When the wind blows across guys, that force is transferred as a downward 
force through the tower to the base. Rohn 25/45/55 were designed to be 
guyed. I'm quite sure the Heights aluminum tower was not.
