[TowerTalk] New FAA regulations affecting towers

[Roger (K8RI) on TT]

Sounds like his antenna may have been a Rhombic.  They were very popular 
for those who had the room back then.

Crop dusting aircraft would likely cut a wire antenna or phone line like 
it wasn't there, but a friend (I went to high school with) misjudged the 
height of a power line and neatly removed the vertical stabilizer from 
his Ag Cat.  With no lateral stabilization the torque rolled it over and 
turned it into a lawn dart. It hit the ground going almost straight 
down. killing him instantly.

Those transmission lines are substantial and wound on a steel core.  
That strong steel core is much larger than any typical antenna wire.
The antenna might bring down a light plane but modern crop dusters are 
built like the aeronautical version of a tank.

We flew down to Visit my wife's folks in Florida over the Christmas 
holidays some years back. A layer of ground fog forming at night is 
quite common in the Florida peninsula and may not burn off until 9 or 10 AM.

A piper Cherokee pilot took off one morning, staying really low. He 
apparently forgot about the high tension lines abt 2 miles W of (IIRC) 
Tampa Bay Exec. He apparently panicked when he saw the first set pass 
overhead and pulled up...right into the second power line. The only 
thing left was the engine and prop rolled into a ball. There was a notch 
in the one prop blade a good inch deep where it hit one of the lines.  
AFAIK power was not interrupted.
They probably replaced that span.

He and his wife lived in a very small house right in the middle of a batch of those 90 ft derricks that we all think of when we think of Texas oil.  Anyway, he had a long length of wire running from his 'mud room' to one of the towers, then to another, etc for maybe 5 or 6 towers and back to the shack. The towers were probably 800 ft spaced.   Fed with a open balanced tuner.  I'm not sure what bands he was on, but he could work DX!!!!!!  RF's got to go somewhere!
