Ron 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: http://home.comcast.net/~kb7qhc/ante.../Cage/cage.htm 73's Richard Clark, KB7QHC 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. 73, Ron W4TQT |
