Typical antenna survival ratings are way less - 402CD, 80mph -- 34XA,
100mph. Even if the tower is good for 130mph, the real hazard could well be
the shrapnel from disintegrating antennas blowing around the neighborhood.
That stuff blows all over while towers fall generally in one piece close to
home. Apparently, the planning folks don't worry about that.
One would not want to wander down to the counter at the city and ask
this question<grin>
I assume it gets handled as the tower is a "structure" and the antenna
is something "on the structure". It's like an inflatable santa claus on
your roof.
From a safety standpoint, if *I* were a county engineer reviewing
applications, and we had agreed that "stuff" should withstand *X* miles
per hour, then I would ask that you list the antenna on your application.
And if you said "I'm putting up a tower with a 2 meter vertical on top"
and then later on you install a copy of W5UN's "mighty big array" to do
some moonbounce, I think you'll get in trouble.
There might be a "de minimus" exception for small things with low mass
and hazard. (kind of like for free balloons.. FAA regs say that if it's
smaller than a certain size and weight, you don't need to do some stuff)
