I'm surprised they ever ... discussed systems that have standing waves, and nothing else. I'm not surprised because you have obviously never cracked open their books - tsk, tsk. Reference page 288 of "Optics", by Hecht, 4th edition, 7.1.4 Standing Waves. What's amazing is that you continue to insist on attributing interference with supernatural powers - "redistribution" being one, ... Obviously, you have never read the following FSU web page: micro.magnet.fsu.edu/primer/java/scienceopticsu/interference/waveinteractions/index.html "... when two waves of equal amplitude and wavelength that are 180-degrees ... out of phase with each other meet, they are not actually annihilated, ... All of the photon energy present in these waves must somehow be recovered or *redistributed* in a new direction, according to the law of energy conservation ... Instead, upon meeting, the photons are *redistributed* to regions that permit constructive interference, so the effect should be considered as a *redistribution* of light waves and photon energy rather than the spontaneous construction or destruction of light." Exactly what is it about the *redistribution* of energy that you don't understand? ... please describe if you would how one would go about actually measuring standing wave current delay - whatever that is. I cannot improve on Hecht's words in "Optics": "This is the equation for a STANDING or STATIONARY WAVE, as opposed to a traveling wave. Its profile does not move through space; ... It doesn't rotate at all, and the resultant wave it represents doesn't progress through space - its a standing wave." In other words, "standing wave current delay" does not exist. Only an ignorant fool would think that it could exist given the equation for a standing wave. Yet this is the current that w7el and w8ji tried to use to measure the delay through a 75m mobile loading coil. The suggestion sounds a little nutty to me, to be honest. Is it possible that you might be mistaken about any of this? I could be mistaken about your ulterior motive but it is hard for me to accept the fact that you guys are just dumb as a stump. I would rather think that you, w7el, and w8ji have a modicum of intelligence and are merely engaged in a conspiracy to hoodwink the uninitiated. Your motive for such is unclear. -- 73, Cecil, IEEE, OOTC, http://www.w5dxp.com |

engaged in a conspiracy Hmm, Trilateral commission? Freemasonry? Area 51? Symbionese Liberation Army? Hussein's "Oil for Food?" Illuminati? Ulster Loyalist Central Coordination Committee? Bilderberg Group? the 4th Reich? AUM Shinrikyo? Animal Liberation Front? Leon Czolgosz? Gulf of Tonkin incident? Hollow earth theory? New World Order? Rosicrucians? Servants of the Paraclete? Watergate? The Nazi-American Money Plot? There is a point in a loading coil antenna where the phase shift is instantaneous? [and yet it moves.....] |

That is what you thought I was thinking you were thinking I thought and you were wrong twice, right once and on the third hand was a draw. |

I was trying to be polite, but yes. Evidently we're in agreement now? ac6xg |

All their measurements proved is that standing wave current doesn't change phase relative to the feedpoint current phase. They did not measure the delay through a coil. They measured the phase shift through the coil using a current that doesn't change phase relative to the two measurement points. The same thing happens with a wire. To measure the actual delay through a coil, traveling wave current must be used. I am apparently the only one who ran that actual experiment. I guarantee if anyone performs that experiment in a valid manner, they will see similar results to mine. Here's the setup that I used to measure a ~25 nS delay through a 75m bugcatcher coil at 4 MHz. http://www.w5dxp.com/coiltest.GIF You should be able to achieve that setup in your physics lab. -- 73, Cecil, IEEE, OOTC, http://www.w5dxp.com |

Did you figure out the Z0 of your coil using the Tesla coil math, and then just assume there were no standing waves, or did you prove the absence of standing waves through experiment? 73, Tom Donaly, KA6RUH |

Hi Tom, There is only the hint of a gejoken experiment. I notice nothing other than a cartoon, and nothing in the way of instrumentation described, much less the vaunted "results" (no doubt the final metaphysical tabulation came from some alchemistry). Certainly no antenna (nor dish reflector that matter). How it relates to a loaded short monopole would probably provoke an essay as elaborate as the coronation oratory for a pope. 73's Richard Clark, KB7QHC |

When asked to do math, he's even more sunk. I'm surprised he even managed to do a "gejoken" experiment. 73, Tom Donaly, KA6RUH |
