John,
Only my 2 cents worth, but for a length that long, I am thinking 10 gauge,
due to the fact it has to support its own weight entirely. 12 would
probably work, but I would fear for its longevity. Is it possible to
support it somewhere along its length? Also, I would try to get a quality
insulated wire. Not just cheap plastic insulation, but one where the jacket
is covered by a protective sheathing. I use this type, but I got it from a
friend, and I have no idea where it came from.
Let's see how the rest of the gang chimes in.

Subject: [Elecraft] Antenna wire question for long spans
I have an opportunity to put up an end fed long wire at our EOC for use on
40,
80 and 160. The span distance is 270 feet, a real handy length for
regional
communication on low bands. Height will be about 65 feet. We will tune
it
remotely with an SGC tuner. My concern is what type of wire will take
that
long of a span and hold up to wind and ice we have here in the midwest.
Would appreciate comments from those who have had long spans of wire up in
the
air.
