That hasn't changed much - there's three kinds of Copperweld rated in 
terms of their resistance as compared to copper, 21%, 30%, and 40%, 
which determines how thick the copper is.

I don't know that his antenna farm  was close enough to the ocean to 
have salt problems. It's about a mile from the shore (approx Portuguese 
Bend), on top of the hill at 1100 ft - he wasn't in "beach front property")

(google "Palos Verdes Peninsula Crest and Highridge" to see where it 
was. https://goo.gl/maps/nPYFBfoW1n8WPg1X9 )  Or google "Wallace Ranch 
Palos Verdes"
