Did you ever take any ME courses Art?
Simplest back of the envelope approximation is 2/3 is best, ignoring
toewr resonance and lower wind as you get closer to ground level, so,
lower points would put more torque on the tower. With an antenna
mounted, it would move the optimal single guy point upward.
It's possible I may have this cimpletely wrong, if so, correct away folks.

I would put them at the center
as I see buckling as the worst danger.
I have also done this with a 60 foot boom antenna
with no problem. I was forced into this position in the first
place because I have a fold over tower and eventualy stopped
using the top guy wires thru lazyness.

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?
Thanks for your help.
AS you said , not recoomeded for only one set at that heigth but the top
set
of guy wires always go near the top of the tower.
