Also - the wind speed at 40-50 feet up might have been considerably higher
than what you "felt" on the ground. Besides, I doubt you were outside for
the whole storm - a decent gust may have come along that "tweaked" your
tower. Be glad it didn't land on you or your house!

Puzzled? First of all, your tower is only rated for 50 MPH - not 76.
The difference in wind pressure is DRAMATIC - over double.
Second if that's really a Tristao tower, then it's getting long in the
tooth. I would estimate that it might be 15-20 years old or more. Plenty of
time for some deterioration in the materials.
Yes, file a claim with your insurance company and then have a
PROFESSIONAL tower crew come in and remove it. DO NOT attempt it yourself.
Welcome to crank-up reality. "Well, if I would've known that the winds
were coming in I would've lowered it." You shot yourself in the foot with
this one. Especially with towers lacking positive pull-down, you're SOL
trying to get it down in a wind. Good luck with your new tower.
