[Antennas] Question about Feedline length and how it might..

Mon, 08 Apr 2002 08:23:54 -0500

What Harvey says is basically true, though antennas fed with coax
have operated while laying on the ground.  Case in point, the antennas
on the former weather site "T-3" had their antennas almost 8-10 feet
below the surface of the ice and always had a good HF signal.
Historical info: Fletcher Ice Island (T-3) used to float around the ice pack
at the north pole and was used by the Russians for part the years,
then the Alaskan command for part of the year and finally the old
Northeast Command with crews out of Thule the remainder of the year.
