You do know that 30' of 25G unguyed will support only a very small antenna and is dangerous to climb without temporary guys of sufficient strength?

(I'm not sure if my earler message came  through, not seeing it....)

I am putting together a permit application with my city which requires 
certfication for 139 mph
for three second gusts as in TI-222 spec. Also steady 100 or 110 mph I think. I 
will review
that.

We are making a 30 foot Rohn 25G tower according to the Rohn specification with 
 4 foot
cube base of concrete with no guys. I'm just qualifying the tower for the 
permit.
