I know that, Tom, but we are talking about measuring the RF voltage between two copper wires one inch apart. The path is well defined. That's one path. It is a no brainer. There is no need for obfuscation. Universally recognized principles of electromagnetics are obfuscation? The measurement proves the voltages at the ends of a dipole to be at least a magnitude higher than the voltage at the feedpoint. You changed the geometry. But even if you hadn't, you might be able to say the changing electrical fields are greater at the ends of a dipole, but not the voltages, because the voltages aren't uniquely defined. Are you not aware of how the ratio of voltage to current varies over 1/4WL of a wire antenna -- 73, Cecil http://www.qsl.net/w5dxp There's not much point in arguing with you Cecil, since you don't want to countenance the more sophisticated ideas of some of the other posters to explain what's going on at the ends of a dipole. That's too bad. You'll give some people the impression that things are as simple as you say they are when things are not simple at all. If they were, even an old hick like me could become an engineer, and the job wouldn't pay much at all. 73, Tom Donaly, KA6RUH |
