Looking at a chart in an old ARRL antenna handbook gives a rough
estiment of a length of 500 feet and a tension of 400 pounds a wire of
around 12 to 14 gauge will drop about 10 feet if Idid it right.


That's useful. Thanks. Did they say what metal it was? I'm guessign hard
drawn copper but if not it may be harder to adjust reckoning for something
else.

They gave two types. Hard drawn copper and copper coated steel. The only
differance would be the weight of the wire and how much tension you can put
on the wire before reaching the breaking point. The type of wire does not
matter, just the weight and how much tension you can put on it before it
breaks.

My recollection is that copper-coated steel should not be used below a
frequency where the skin depth is less than a few times the copper
coating thickness. So, there is a minimum frequency vs copper thickness.
