Mine is 10 feet from the NW corner of the garage.
The top antennas are at 130 feet.

OTOH I saw one that came down from 80 feet with no ice and went through a

I'm not sure about sick trees, but we had an F1 tornado (not terribly
strong) take the tops out of trees and only shake the tower.

The only TVI I've had is when operating 2-meters and watching channel 12 on

2-meter array on the same tower and all the coaxes run together.
Suprisingly, there is a second antenna with preamp pointed in a different
direction and it receives no interferrence. I'm guessing it's in the one
