I should add that I am not sure why you are using rope instead of the
antenna wire to hold up the inductor. BTW, it's easier and more efficient
if you just top load the vertical wire with another wire going toward the
ground.

So you did not use an insulator at the high voltage end of the wire? I
never relied on rope being a good insulator. If you do not have one it
should be easy to make an end insulator by putting two holes in a section
of PVC pipe. PVC pipe was readily available on every island that I have
ever been to.

I have about a 67 foot vertical with about 50 uh coil at about half way up
for
160m. Antenna worked great until this morning it melted the rope which was
used to pull it up through pulley at top of my telephone pole. Antenna fell
missing house literally by less than 4 inches.
The 5/16" double braided Dacron which was taped out about 8 inches in
effort to
insulate it was melted at end of tape.
I don't have much in way of supplies but want to know whether rope would be
more likely to melt if attached above coil or below coil.
Then to find a bucket truck. I can't climb a telephone pole without steps.
