Where is it written that a self-supporting tower has to be guyed with
the same tension as a guyed tower?  Why can't the guys on a
self-supporting tower have no to little tension?  Think about it.  Those
guys can be there only as a secondary method of supporting the tower.

That means they guys on my tower exert an additional 3300# on the base.

That is well more than double the total tower and antenna system 
weight.   Free standing, or Self Supporting towers are build 
considerably stronger than guyed towers as they have to serve the 
function of those guy wires internally. Some are designed to allow 
guying as well.  The question them becomes, If permitted how does guying

the self supporting tower affect the wind load and weight support 
ratings.  Guying a tower with properly tensioned guys can easily add 
more than twice the load to the base.  So a 1500# tower could end up 
with 4500# on the base structure.

IF the tower manufacturer says their self supporting tower may be guyed,

stick strictly to their recommendations as to guy strength, tension, 
wind load, and antenna weight.

I'm surprised a reputable manufacturer would recommend guying a self 
supporting tower.
