Sometimes I feel like Galileo up against the Catholic priests. Like Galileo, I may not live to see the technical facts accepted by you gurus. Tom, you cannot seriously assert that the standing wave current changes by 90 degrees in 90 degrees of monopole when simply mathematics proves that is not the case. For a pure standing wave, Io*cos(kx) is the amplitude. cos(wt) is the phase. It is obvious that the phase of a standing wave doesn't change with (x) - it only changes with (t). What is it about Gene Fuller previous posting with which you disagree? Gene Fuller, W4SZ wrote: In a standing wave antenna problem, such as the one you describe, there is no remaining phase information. Any specific phase characteristics of the traveling waves died out when the startup transients died out. Phase is gone. Kaput. Vanished. Cannot be recovered. Never to be seen again. The only "phase" remaining is the cos (kz) term, which is really an amplitude description, not a phase. Cecil, I don't know how to break this to you, but, you're not Galileo, not even close. You and Gene also got the formula wrong, or at least you didn't get the complete formula for two waves passing in opposite directions deep in the night. It's doubtful you even know what the kx in your formula really stands for. 73, Tom Donaly, KA6RUH |
