Hahaha..

Most all copper wire on the market is soft draw
and will break after a few years of constant

tension. Hard draw copper wire is very tough

and robust. I use 18g lamp safety wire. This is

the thin copper wire that servers as a safety

ground and as a safety wire in case a link in

the lamp chain breaks in hanging chandeliers.

Copper wire should NEVER be used as your ground because ( the reasons
you stated, in addition to... ) the inductance value is **** poor.
Copper strap is always desirable over wire. FWIW, many people, hammies
included, feel they are using copper wire when they are in reality using
copper COATED wire. No matter,,, copper wire doesn't compare to copper
strap.

Strap is better, but due to skin effect, you could copper coat steel and it
would work as well for rf as solid copper. Hmmmm .... come to think of it,
they do make that stuff.

I used to use 8 gauge copper wire for my longwire antenna. Despite being
held by several trees and anchored at the house, nothing ever brought it
down. Nothing like a *lot* of copper. Come to think of it, it was several
hundred feet long and worked gangbusterly on 160 as well as the other bands.
25 watts and I was solid pretty much across the country at night; during the
daytime, I still pounded into Washington D.C. from Rochester, NY using 65
watts. That was on 160. 15 and 20 meters and 75 watts worked the world
with no problem - other than the fact that the pattern of that antenna was
real strange. I never got more than a fair report from England, but Norway,
Sweden, and Denmark would always give me a report of a very strong signal.
Same with Italy.

Regardless, I'd never use anything as light as 18 gauge wire for anything.

Skin effect changes the inductance value to equal that of copper strap?

Looks like summer is on the way for you guys. Enjoy.

I can't believe that No one reads anymore?
The wire is Hard Drawn Copper, not plastic coated or Copper clad!
Someone got a nice deal for $9.99, went to Canada where maybe they have
other things to do but complain:-)

Would be a real deal if you would keep the cheap STEEL plastic coated wire
and just offer the insulators alone.....I like the wire ties you have on
the
wire....made for tying reinforcment steel in concrete.....so is the cheap
antenna wire you offer with the insulators.

a BAAAAAAAD deal!

They're not known for being terribly bright up there in CanaDuh.

Even hard drawn copper stretches with time.

Copper clad is not that bad if the cladding is thick enough. A vendor
can improve profits if the copper cladding is kept to bare minimum.
There are two real problem with copper cladded steel. One is the
plating process itself. If it is not uniform and thick enough t hen
mositure can penetrate the copper plating and cause the underlying
steel to rust. Once that happens the radiation resistance goes south
big times. The second issue is that any protective coating on the
copper is missing or damgaed will cause copper to oxide. Copper
oxides are not conducting. The antenna performance then goes south in
a big hurry.

Even hard drawn copper is subject to oxidation if not protected. While
the effects of copper oxides on the very thin surface is marginal at
frequencies below 30 MHz., they can be disastorous at frequencies in
the VHF regions and higher.
