I am attaching a few of your quotes in this thread. Sorry to hear about your total loss of short term memory. I'm in a learning process here and using the scientific method to correct my mistakes. Isn't that what rational people do? [Direct quotes from March 5-7] Standing wave current is a net charge flow of zero. I was corrected on that one and already admitted my mistake. The charges obviously migrate from end to end in the antenna. Surely you understand that standing waves in a transmission line don't flow - they just stand there, which is why they are called "standing waves". Exactly the same principle applies to standing wave antennas. This means the same thing as your posting that phase is gone. A phasor requires a rotating phasor to exhibit flow in the real sense of the word. Standing wave current doesn't possess a rotating phasor so it is not flowing in the normal sense of current flow. If you think standing wave current is flowing, how do you explain 0.17 amps at the bottom of the coil and 2.0 amps at the top? http://www.qsl.net/w5dxp/current.htm bottom of page The two traveling waves have to be analyzed separately and then superposed to obtain valid results. Don't see anything wrong with that. If one uses the standing wave current phase to try to measure phase shift through a coil, one is making a mistake as has been demonstrated here. The currents that are doing the flowing are the underlying current components, the forward current and the reflected current and they are close to equal. Everything you say about a coil is true for the forward current and the reflected current. It is simply not true for the standing wave current which is just a conceptual construct and not a flowing phasor at all. You said it yourself, Gene, phase has disappeared from standing wave current. Do you understand the implications of your statements? -- 73, Cecil http://www.qsl.net/w5dxp |
