Please don't get upset! I don't intend to actually do this!
All you antenna experts out there. If I have a tower say 60 feet tall
and
I can only put one set of guy wires up, should they go near the top of
the structure or near the middle?

What are the forces that the wind exerts on a tower and are these
forces evenly
distributed?


If the tower is 4 feet across at the base, you may not have a problem,
otherwise - If you do that, be sure the tower is more than 60 feet from your
house - so it will miss the house when it falls.
Most of the water towers you see are a hundred feet or higher, but have no
guy wires, because the base is pretty wide.
guying at the top only may cause it to bow in the middle during a windstorm
to such a degree as to collapse.
I would guess the tower manufacturers would have wind and static loading
data available.
You have wind loading and the static loading due to gravity - which begs to
become dynamic.

try practicing with half-inch pvc water pipe - see where the guy wires do
the most good.
