as a vertical, I think this antenna exceeds the max hieght of an amateur
antenna, which is 220 feet.
a half wave with a quarter wave at 160 is 80 meters plus 40 meters approx,
which is approx 360 feet vertical.

William,
As long as the FAA and NASA don't object, and you have the
money
to pay for it, there is no maximum height for amateur antennas.
There is a practical one, though. Who would you get to climb it
to
change the lights when they burned out?
