I understand that even with the regs insurance is difficult to get and
very expensive if you find some.

Yes. 140 MPH is "Miami-Dade" specifications for windows, doors, etc.
and is incorporated in the building codes of most of Florida these
days. Seminole Country, FL is no different. The insurance industry
has pushed that on a growing part of Florida following hurricane Andrew
and every other major hurricane for the last 30 years.
Unfortunately, building regulations have stupidity built in ... like
tile roofs that act like an fission reaction (when one tile breaks it
creates shrapnel that breaks five or six more tiles resulting in the
loss of tiles in an entire neighborhood <G>). Applying the same 139
MPH standards to a 50 foot tower surrounded by trees and tow story
homes as applied to 1500' commercial towers is a bit absurd but that's
the rule statewide.

Subject: [TowerTalk] Tower installtion question
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
## Do they want your living room windows to survive a 139 mph wind

Every tree in the neighbourhood would come crashing down, and u would
have zero
shingles left on your roof. Your fence would be half a mile down
the street, and your
car would be flipped over in the driveway. Your roof would be ripped
right off.
## What happens when trees topple your 24 foot tall tower ? Do they
also want the
3 el yagi to be able to survive 139 mph wind too..or just the tower +
mast ?
## I can see where they could then make a case for the yagis to
handle 139 mph.
If the 150-200 lb yagi came crashing down..onto philystran guy wires,
it would slice em
in half.... bringing the tower down. In effect, they are doing an
end run... effectively
banning all ham towers. Once they have effectively gotten rid of
new ham installations,
word will spread to other towns nearby..as Mayors like to brag about
this stuff. The other’s
will follow suit. “want to get rid of ham towers...just impose a
MIN 139 mph rating on their
tower, ants, mast,coax, guy wires, rotors, and anything else you can
think of. “
Bye-bye ham radio.
