[TowerTalk] Long Wire Sag

[Ken]

I see you are not capitalizing "copperweld".  Copperweld is actually a 
trademark and company name.  Most of what I see advertised is "copper 
clad steel" and I wonder if the cheap wire we buy has thinner specs than 
true Copperweld.  OTOH, I see that Copperweld has been acquired and is 
now headquartered in China, so maybe (or maybe not) capitalized 
Copperweld does not live up to it's old reputation.

Speaking of 70 year old Copperweld, when I was a young ham in high 
school (50+ years ago) I received an "antenna kit" from MARS.  It was 
for a rhombic and included a 5200ft roll of 3 strand #12 Copperweld.  I 
still have some of it left.
