[ARC5] RCA AVA-120 antenna questions and some other ones too...

[Robert Downs]

To add to what Mike wrote, according to SIG 5, W-106 and W-106A (Signal Corps Stock Numbers 1A106 and 1A106A) are #18 AWG Copperweld.  The only difference given is that W-106A contains more steel (and presumably less copper) and has a higher tensile strength.

You might also try Fair Radio.

The original W-106A copper clad wire is .039" in diameter, according to a B-29 drawing I have here for the liaison antenna, but I just use #18 Copperweld, which is about .001" larger in diameter.. Though there are plenty of vendors, I've gotten the copper clad wire for years here - https://thewireman.com/product/antenna-wire-18-awg-copper-clad-steel/
