Current across the antenna loading coil - from scratch

Of course, *everyone* except you and Tom Donaly are talking about charge stored over a whole cycle. Bull. That's the entire base of their arguments. The unbalance in the *RMS* current at the bottom of the coil and the *RMS* current at the top of the coil is what the entire discussion is all about. The currents measured by W8JI and W7EL were *RMS* currents. The currents reported by EZNEC are *RMS* currents. And the capacitive currents can also be measured in RMS terms. So what? And no one but you brings up "net storage". We are all talking about ordinary capacitive charge storage within a cycle. If so, that is completely irrelevant to the discussion since W8JI and W7EL are using *RMS* currents for their measurements and EZNEC is reporting *RMS* currents. Let me summarize it for you. W8JI and W7EL apparently think that the RMS current value of zero at the bottom of the coil Vs the RMS current value of one amp at the top of the coil means energy is being sucked into the coil from some external source. I don't read their responses that way. I read their responses as saying that the current leaving or entering an end of an inductor includes a capacitive component and an inductive component. The capacitive current branches out of the coil to the surrounding space, and is what allows a measured difference in the currents passing through its two ends. The path through the wire to the other end is not the only path for current. How about assisting in a tutorial on standing waves rather than diverting and obfuscating the issues? I'm trying. |
