Hi

I worked for Collins radio in the mid 60's and they made this antenna in =
the building I worked in. Although I didn't work on that project if I rem=
ember right the wire was rolled out from a large wench with a cone on the=
 end of the wire. Then the plane circled and the wire would form a helix =
below the plane. I think the wire was about a mile long. One problem with=
 it was the huge static charges that would build up on the plane. I remem=
ber the cones stacked up in the basement they were about 4 or 5 feet high=
 each.

Trailing-wire antennas are the reason we call end-fed long wires "Zepps",
since they were first used by Zepplins.

But allow me to point out that if you fly in a turn until the trailing
cone on a long wire is in front of your nose, you are probably flying in
a descending spiral.

Not sustainable for a long QSO....:-)
