Seminole County, FL was 100 MPH based on the old "fastest mile"
standard. Without finding a new chart that uses "peak gust",
139 MPH would seem to be equivalent. Requiring the calculations
or a PE certification for building permit is within reason under
PRB-1.

Greetings,
My local city Building Department wants me to prove that my proposed (24 foot)
tower
installation with a 3 element beam for 17m & 12m can withstand 139 mph winds
before they
will issue a permit.
Does this sound even remotely reasonable and compliant with PRB-1 ?
Thanks for your views - Brian Carling AF4K
