Wouldn't using all 3 wires give me the effect of a larger diameter wire which

Hi Ron,

Sure, but you have a tuner don't you? If it was short and fat, yes,
it would lower the load on re-tuning, but you've gone for long and
thin. 3 wires in a bundle is not very broadening until you get into
high HF (and barely there). You have to remember that all things
explained about antennas eventually are boiled down to a simple
relationship between wavelength and physical dimension; this includes
how "thick" an antenna might be considered. An example of this:

Richard,

Yes I have a tuner, but I prefer a broad resonance curve. I compared two regular
whips, one thin and the other maybe 3 times as thick. The thicker one seemed to
have a broader tuning characteristic and required less length to resonate at a
given frequency.

Anyway, since there are three wires in the cord, I thought I might as well use
them. Three wires may not be be much better than one, but at least they
shouldn't be worse. The extension cord is the round type and looks more like an
AC cord than an antenna. That's why I am using it.
