Even tall, unguyed structures tend to fall in on themselves although they would form as close a knit pile as the guyed tower.
The acelleration of a tall tower tipping over will cause the top half of so to bend back on itself.


I'd sure hate to have the liability of a tower near final approach to any airport.

A few years back a TV station installed a tower near HTL. Actually it was within the 5 mile radius of HTL and they didn't even have permit, nor had they gone through the paperwork with the FCC and FAA.
I believe the top of the tower is near or over 900 AGL. BTW that tower is almost in the pattern for a public gras strip near the SW corner of Houghton Lake. You have to watch out for the guy wires when landing to the north and when you take off you have to go around the state police tower about a half mile off the end of the runway.


The tower had been constructed, but there weren't even any lights on it yet. Not even any part way up.

The tear down order had been written, but they pleaded and received a reprieve.

I wouldn't think so, generally the AM broadcast tower is insulated at
the base and fed there, so, generally no coax on the tower.  Some
installations decouple a bit and put a microwave linking antenna or
something on there, but not often.

Generally the guyed towers screw themselves right into a ball as the
weight/tension/pull of the guy wires brings it to the ground.

The tower cllapsed on itself after being struck by the
amll plane

Would the presence of the heavy cable(s) have contributed
the tendency of the tower to collapse down rather than
out?
