Why do you believe the "net" current somehow has different properties than simply the sum of the two component traveling current waves? Because the net current is a *STANDING WAVE* made up of equal magnitudes of current flowing in opposite directions. That makes the net current zero, Gene. Standing wave current doesn't flow. The RMS value stands still. Standing waves are only an artifact of the superposition process. Everything that needs to be known involves the two traveling waves that cause the standing wave. Asserting that standing waves flow into the bottom of a loading coil and out the top shows a complete ignorance of how standing wave antennas really work. After that false premise, none of the associated conclusions are valid. Standing waves are not static. The RMS value of a standing wave at any point is indeed static. The current may not "flow", whatever that means, but there is certainly real non-zero current at every point except the exact nodes of the standing wave. If you prefer, the standing wave current oscillates rather than flows, but that is of no special importance here. It is of infinite importance. If the standing wave current oscillates in place, it doesn't flow through the coil. W8JI says it flows into the bottom of the coil and out the top. Nothing could be farther from the facts of physics. Why do you believe standing waves are somehow inferior to traveling waves? Standing waves are an artifact of the superposition of two traveling waves. Standing waves have a constant differing RMS value at every point on the transmission line. Traveling waves travel and have the same RMS value all up and down a lossless transmission line. What is it about that concept that you don't understand? -- 73, Cecil http://www.qsl.net/w5dxp ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= East/West-Coast Server Farms - Total Privacy via Encryption =--- |
