I'm no engineer, but my guess is the individual DC resistance of each wire will not change one iota; therefore, the total DC resistance will not change, either. Then, continuing my guess and ignoring non-resistive impedance, any RF energy introduced at the feed point will be dissipated equally along each wire in a manner similar to resistors in parallel.
Please let us know what you find out. Gus, KG5OFB On Thu, Jan 16, 2020 at 2:57 PM Rick Hiller via BVARC <bvarc@bvarc.org> wrote: > I am in the midst of analyzing a Ham market HF antenna.
