One would not want to wander down to the counter at the city and ask
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
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)
