The short answer is, "yes they can."
There is a PDF file that details the required wind loading "design to"
that can be perused by googling "antenna wind load for seminole county
florida." Your QTH on Sterling Pine St., is between the datum line for
140 MPH and datum line for 130 MPH design requirement. The PDF file
explains that interpolation between requirements is allowed so a 139 MPH
design falls within those two datum lines. The tower vendor should be
able to provide qualifying data for their product(s) on wind loads but
the "design to" requirements do not appear to be height specific. The
PDF file is fairly informative about living in a tornado and hurricane
prone area, historical wind speeds, airborne residential debris,
including the probability of having that experience in Seminole county.

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
