Copperweld antenna wire tallroger on 17/11/18
Has anyone ever tried MIG welding wire? It comes in various diameters, the most common being .035 and .045. It is steel wire, but copper coated to prevent rusting. I have never heard of it being used and I was wondering if there is a reason why this is so?

feed line length question KK4BHS on 19/5/17

I notice older Handbooks suggest a 1/4 wavelength feeder (or multiple) to a 1/2 wavelength zepp, while later ones list a length that appears to be a multiple of 1/3 wavelength (42 feet). Parallel currents or feedline radiation are mentioned, but not a lot of explanation of why they exist or where they come from.. Can anyone add more details?
