As opposed to 'fake' copper wire?

That wire looks really fragile. Can you do it in steel? Braided
copper?


yea right May 8th 05 04:58 PM

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.

I have 50' of thin braided copper wire from Home Depot that's been
under constant tension for 6 years 9 months. Enough tension to
deflect the top of a 20' support (two fence rails, a spike base and a
building clamp at 9') 2 to 3 inches.

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!

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.
