No one will be able to answer your question without knowing the load you
intend to put on the tower and without doing the engineering work. You
definitely can have less than 80% guy anchor radius, however this puts more
stress on your tower, so you may need a stronger tower and a stronger guy
system. You could use elevated guys as you suggested, however they would
have to be quite tall to achieve the Rohn standard guy wire angles. There
is a lot of stress on elevated guy posts and they require a lot of concrete
and of course they need to be engineered.

I would like to install 170 feet of Rohn 45 tower. The problem is that the
specs call for guy points to be 136 feet. My lot is only 170 feet wide
which will give me about 96 feet on each guy point. Is there anyway to
elevate the guy points enough, such as using H beam to make this work, or
increasing the size of the guy cables, pouring additional concrete, etc, the
tower can be bracketed to the poured concrete bond beam on a concrete block
garage at 10 feet if this would help. Any help or ideas would be
appreciated. Thanks Paul WN4AMO
