There is not the slightest bit of disagreement on the nature of traveling waves and standing waves. On the contrary, you must not have read W7EL's recent posting where he again presented his coil delay "measurements" using the standing current phase as a measurement reference. Remember, the current you said contains no phase information? Maybe you should share your knowledge with W7EL? The only person who was ever appeared to be confused was you. I am happy Regarding the cos(kz)*cos(wt) term in a standing wave: When you made your posting, you reinforced my argument better than any other reference. I am very happy with your posting and cannot thank you enough. I will continue to use it as one of my best references for the invalidity of W7EL's coil delay measurements. 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. -- 73, Cecil http://www.qsl.net/w5dxp |
