I'm just wondering if you have worked with 6 awg copperweld. I have not but
I would be concerned with its stiffness and springiness. I have used smaller
copperweld for temporary antennas in the Caribbean and I had disappointing
results. The copperweld kept breaking.
W6GJB had the same experience.
The #8 we have stretched to #9 is pretty strong, stronger than THHN,
which stretches when it's under tension for a while. The 80M dipoles I
built with #10 THHN had to be lowered and circumcised every few years to
keep them within tuning range of my 87As. I've not had that problem
with the stretched #8, which is very close to being hard drawn.
