Just for the record, I have had 65' of Rohn 45 with a 6 element tri-bander
and a 2 element Hy-Gain 40 meter Yagi installed in two locations.
The first installation in New Orleans went through 2 hurricanes of rather
significant force, and the same combination later went through another
hurricane in Houston.
No damage occurred in any of these mother nature challenges.
I would estimate winds, in all cases, to have exceeded 80 mph.
A fourth major blow occurred later on, when a tornado came though Houston
and completely demolished my 22' mast which was of less than proper strength.
Wind bursts, in this case,,,, who knows??
This same tornado wind did destroy a 50' windmill tower about 3 miles away
from my house. I presume it took the main funnel as a part of it's demise.
Although I now have the tower properly guyed, the fact of the matter is,
the above installation(s) survived quite well on all occasions.
I hasten to add that I don't recommend this as a proper installation
technique, but it is actual testimony to a tried and true field test of
epic proportions.
In other words, I've run the test, and you can now use this information as
fact when it might come to your wondering about how stout is 60'-65' of
Rohn 45 tower.
