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.

"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?
