One thing that would affect RF conductor resistance is the paramagnetic properties of the conductor. If, for example, it was bare iron or magnetic steel wire, then we would have eddy current losses. And those losses could very well be much larger than the ohmic losses measured at DC.
The wire should be non-magnetic; if it IS magnetic, then it needs to be plated with a sufficiently thick non-magnetic material or the losses could be quite high. Owen Duffy (ex- VK1OD) nicely explained this some time ago on his old web site. (His new site is owenduffy.net). Exactly how magnetic wire would affect a Beverage antenna, I'll leave for others to expound on. Or measure. :-) 73, Mike www.w0btu.com On Wed, Dec 3, 2014 at 1:36 PM, Tom W8JI <[email protected]> wrote: > > RF losses are best measured, because loss involves: > > 1.)
