For an EOC operation, you want an omni direction of coverage. Put a usual
antenna height, and end fed 270 foot wire on 40 m or even 80, is going to be
getting to be directional toward the far end of the wire.
MUCH better for EOC use is to put up such a wire as a center fed doublet.
Then it cou

John,
I found this web site looking for wire for a friend. He volunteered
for a military airplane restoration club in my area. He needed a wire that
could take the prop blast. One of the wires was as close as he could find to
the original wire specified by the drawings he found.

My house is surrounded by trees.
I have 500 feet of wire threaded over and through
the trees using a catapult (slingshot). The wire at
the far end descends to

Go to

and check out WUN(TWA).
I'm not sure it is practical for Ham use, but its cool stuff.

John,
I have no direct experience with your icing/wind conditions, but I would
figure that #12 copperweld would be the best weight to strength ratio that
you could muster.
If you can support the wire at a midway point, the weight will only be a
factor over half the span length, the sag will be re
