Note that Don said " RF Ground will be that point of zero RF voltage - in a balanced dipole, it will be present right at the middle of the center insulator."
"Dipole" is the important word, meaning a radiator 1/2 wavelength long. A full wave center fed antenna (two half waves in phase) will have a voltage loop - high impedance point - at the center of the center insulator. As the center fed antenna is made shorter than a 1/2 wave, the impedance at the center also rises. Think of it as "stuffing part of the antenna down the feed line" to make up a 1/2 wave. 73, Ron AC7AC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
