[Elecraft] Seeking loop Antenna Parts

[Clay Autery]

The rigging you describe is almost exactly what I am planning.

I can replace broken 14 AWG THHN 3 times for the price diff...  IF it
breaks... and I will simply use a non-stretching down-line on the
tension weight and monitor its descent toward the ground to determine if
and when to trim the loop back and re-terminate.

I'd use that snazzy, 30% copper over steel stuff if I didn't have the
system/access to maintain/replace the loop and I needed it to stay put
for years and years...  the insulation vs. bare wire has some measurable
impact on radiation characteristics, but at this point, I'll just get a
loop in the air so I can get on the air when I finish assembling and
testing my K3s.

Thank you and ALL of y'all for y'alls help and opinions, et al.  I have
lots of new information and docs to read/study.  :-)
