Just acquired a couple reels of electric-fence wire from someone who got
smart and got rid of her horses. Question: is this wire (seems to be
aluminum) useful for antenna applications?


Lots of things are sold as "electric fence wire" in this part of the world.

One of them is a 2.7mm diameter aluminium wire with a HT steel core. The
aluminium is sufficiently thick that it is a ver good antenna wire, it is
strong and has effective RF resistance not much higher than copper.

On the other hand, we can buy HT steel wire with a flash of Zal (Zinc-
Aluminium) plating coated then with polyeurathane. Makes an appalling
conductor for low HF.

You will need to take the effort to better describe your own wire to get a
worthwhile opinion.

It's solid and uncoated- no core. Looks like aluminum (I've worked with
stainless steel wire and this wire ain't steel). Quite flexible. And the
price was right.

I would think that if it's strong enough to hold up it's own weight
(plus a little more) then it should certainly be usable for an
antenna. Making connections to aluminum isn't exactly easy at times,
but can certainly be done. I've used the coated-steel type electric
fence wire, the hardest part about using it was the mechanical
aspects. It loves to kink. The best antenna wire is whatever you
happen to have enough of at the time, right??

They sell aluminum grounding blocks at the hardware store, basically
aluminum bars with screw threads every half inch or so. These are cheap
and easily broken into usable splicing blocks, using a hammer and a vise.

I use these for mid-air splices on my loops, and for the radial system
for my verticals. Again, remove the screws, break as needed (remember
Cinch Jones barrier strips?), good DX!

I tried 16 gauge Al wire and it was too soft & weak for anything. I
use it for bundling stuff now.
I would sure hate to depend on that to keep the bull next door!

It'll probably be okay with 50kV applied to it.

"Appalling conductor"? How so? In radio school they tell us a wet piece
of rope can be used in an emergency; where does that land on the
"appalling" scale?

Missed this whn I first read it.

Seems a polyurethane coating would render the wire useless in an
electric fence use.
