    Has anyone ever tried using wire from a wire feed welder for antenna wire?

    Variety of sizes .024", .035", .045", .063". You can get with copper on it as a rust inhibitor, so copper coated steel. Literally 1000's of feet on one roll 50# roll will run some where around $200. Should have a fairly high tensile strength and fairly light weight.

    What on your thoughts on this?

    The wire welding wire I tried to use rusts all up in less than 1 year. It has a copper flash as a rust inhibitor. It is NOT copper weld.

    I suggest you take a chunk and lay it outside for a while, you will see what I mean. here in Georgia I have to store my mig welding wire in a refrigerator to prevent rust. Being indoors is not enough.

    I kinda wondered how it was applied and if that would happen. At the rate we use it, it never has time to rust!

    Anyone tried using stainless mig wire?

    I'm sure - it's a regular question.

    Challenges are attaching the feedline as well as getting it to be straight. Electrically, it's not perfect, but it should work fine if it's the best you can afford.

    If you are trying do it cheap then try electric fence wire. A lot cheaper than MIG wire and wont rust.

    MIG wire for me is free. I was also wondering about power handling issues? I would only be at 100w which I know would be fine. What about 1500w?

    If you're not interested in anything more than a temporary antenna, and don't mind replacing your antenna often, then use your free MIG wire at whatever power level that you like.

    W8JI had better MIG wire than I did. ;-) The MIG wire I had didn't last anywhere near a year.

    I made a horizontal loop around my house with sainless .045 wire and had poor results. It touches the roof shingles in two places though so it is far from ideal. I made mecahnical crimp connections to the coax with good results. More experimenting when it gets cooler out !

    I go camping several times a year in the National Radio Quiet Zone, I install a approx 600' loop of .035 mig wire.

    Shout out to the Easy Hang slingshot- it's the way to go.!

    It is a fantastic, inexpensive, TEMPORARY antenna wire.

    I think the wire costs me something like 2 dollars a antenna, when the weekend is over it is not a strain on the wallet to collect the wire and discard it.

    I read somewhere than regulation "Copperweld" antenna wire is 40% copper, for a permanent antenna it is only a few $$ more.
