Antenna wire, get your cheap antenna wire
« on: July 10, 2020, 1913 UTC »
Just picked up three 500 ft spools of #14 insulated hookup wire, about a decade ago I switched to this from official "antenna wire" which is more expensive and more of a PITA to work with, as it likes to kink up:

It arrived today, and looks good, brand new spools and everything.

He also has #16 for a little less per roll:

Back in 1992 I bought from an INDY electrical store a 500ft spool of solid copper #10 AWG insulated wire that lasted me for +20-some years. Made all sorts of antennas with that, and not just for me, but others as well. Heck... It's what my Windom consist of. I see wider bandwidths with it too. Today, when I see contractors rip that out of buildings and houses, I help myself to it, before they do it 1st.
I can't decide upon what's worst, young and stupid, or old and chemically dumbed down.

Have used THHN building wire for antennas for years (mostly because of its availability)
in spite of speculation that the annealed copper will stretch and possibly fail.
Have never had that problem... the antennas survived years of ice and wind storms.   
If you use insulated stranded THHN wire outdoors, be sure to seal the exposed ends from water.
You would be amazed at how well water will wick the length of an antenna and corrode it from within
so for that reason, solid THHN is the better way to go.
Be aware that the NEC requires hard drawn copper or copper clad steel for antenna wires.
In any case, NEVER run a wire antenna over or under a power line.

I got a spool of this. Very quick response, and he even emailed me beforehand to find out what color I wanted, which is very important to those of us who are fashion conscious.

Reminds me of the old joke, which I know I've repeated here before, but please indulge me:

Wife, when electrician staggers home very late: "Wire you insulate???"
Electrician:                                                           "Watts it to you, I'm Ohm ain't I?"

One of my spools has already been put to good use, I built a 250 ft V Beam antenna aimed to Europe. More details to follow when I get the chance to type up a post.

I have been using copper-clad aluminum speaker wire for several years now. Mostly for ground radials and some temporary receiving antennas. I am not sure how it would fair for a more permanent install in the air, though. Anyone else using CCA wire for antenna projects?
