That's a good point. I didn't think about flying objects breaking the
tower wires on the extenders. Every engineering solution has its down
side.

Then you will appreciate this: after one of the major gulf coast hurricanes,
in the 70's, an engineer from Miami was hired to settle some tower
destructions. One, which failed at about 80 feet and collapsed was examined.
The measurements on the damaged section that caused the failure exactly
matched the shape and mass of a cow which had been picked up and hurled into
the tower 80 feet over the ground. You can not designee for the occasional
flying cow.
