On-the-Fence a {Low Level} Windom Antenna [Was : Even more on antenna feedlines and matching to an antenna.]
I've always wondered how this antenna would have performed if the
feedpoint had been in the center as a classic dipole and the xfmr
Z-ratio was different than 1:1. Would this allow some semblance of a
"multiband" antenna as opposed to the direct feed or 1:1 situation
where the antenna essentially is optimum on the primary freq and the
3rd harmonic? Why did I choose the Windom? Because the radio room is
directly across from the 35% length point on the antenna. Even though
it works well I'm not convinced that there is anything "magic" or
unique about the 33 to 35% point on a wire antenna unless there is a
true overall impedance averaging effect when fed at this point. (???)
