That's right...it's insulated and is used for "invisible" dog fencing.
I've used it

it came in 500ft spools.

I bought a conyne delta kite for lifting antennas once. It had 400' of cord on
it and would sit there high in the sky not moving. Sadly I never had the
opportunity to hang an antenna from it. You need a lot of space, with no trees.

Greetings to All !
Thank you to everyone who has responded to my original note.
Looks like I will have to do my own search for the balloons as
no one included a source for them BUT did include lots of great
user info.
Again, thanks.
As in my past, I will be generating the H2 gas where
We tried a balloon vertical at V47 in the 80's. We used an advertising
balloon. It kinda worked but it kept getting pin holes in it. We
believe it was from the sand in the air. Our location was just off the
end of the runway in St. Kitts. We got a visit from some official
looking
I would add to the conversation that you must know what type of insulation is
on the wire. I picked up about 5000 ft. of 20 ga. wire at a hamfest and I used
it to put down about 70 radials on my shunt fed tower. I also used it for a
dog fence. About four years later, the dog fence wire
I believe this wire is insulated. It is for things like an invisible
fence. I am not sure what it is made of.

to rust. Also, long thin runs of steel may not return RF well.
For permanence it's a lot better to invest in 3000 feet copper that
can provide sixty 50 foot radials. That will at least
I'd look into some kind of drone for this.

Having watched/been watched by the TARS aerostat radar off the coast of
FL, I would think that the "balloon" shape that generates lift with wind
would be the better choice for 160m verticals.
Helikite also balloon plus kite

Never tried one, but
What about using a kite? Dad used to have a WW2 Air Force box kite used for
emergency communication by downed pilots. We didn't have the antenna wire so
it usually broke whatever string we tried to fly it with, but it would easily
have lifted a 160m vertical.

I got too many replies to reply to each of you individually, but thanks to
all of you for many helpful suggestions and recommendations.
I appreciate it and hope to have a much louder signal on 160m before too
long.

I did this some decades back using met balloons, they were about 4-5' diameter,
supporting a 1/2 wave or 5/8 antenna. The wire must have a DC path to ground to
discharge static.
I bought the balloons from a carnival novelty shop!
They work great of course, but no use if it's windy.
