I had an 80 half wave inverted L, up 67 out 70 feet, made of #12,
strung with great difficulty between two tall trees, that really
worked well. The vertical came down to my tractor shed from the
western tree and went through the wall with insulation to an tank
circuit tuner on the inside wall. In a lightning storm all the #12
from the outside of the tractor shed to 3/4 of the way to the eastern
tree just simply evaporated.
There were no obvious char marks anywhere, and the tuning network was unharmed.
If it could to that to #12, doing it to #17 would be easy. Not that
I have any technical explanation for what happened, just that it
happened.
73, Guy.
