Years and years ago, they used to make a heavy copper plated steel ant
wire, anyone remember it? It was great, took years of abuse, snow, ice
and high winds at a cabin of mine in the high sierras (11,500 ft
elevation) and, like a timex watch, kept on ticking...

Years ago (like about 2 yrs) and even today (like now)
Copperweld makes it.
I have some 300-ohm transmission line made from copperweld conductors.
Look into the belden catalog and anywhere you
see the "Copperweld" trademark uses copper-coated steel.
