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:-) "Beau" wrote in message ... 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!

Someone got a nice deal for $9.99, went to Canada where maybe they have other things to do but complain:-) ****** 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. james |
