I actually tried to find some dead soft strip (3003 would’ve been great!), but in this size all I could find was 6061 and 6063 (in either T5 or T6). If I do it again, I will go with the 1/16" thick strip instead of the 1/8". My test system is up and running, but not giving very good results compared to my first station. But the feedline on this helix is over 20ft longer than the other, and using RG-58 instead of RG-8X. I’ve got two more setups to try before moving the antenna (using a 5’ line LMR400UF feedline, and using some combination of a cheapo LNA with the existing feedline).
