I already posted, years ago, measurements at: http://www.w8ji.com/mobile_antenna_c...ts_at_w8ji.htm Those are RMS standing wave measurements. To see what is wrong with using RMS standing wave measurements please see: http://www.qsl.net/w5dxp/travstnd.GIF I think what is happening here is you are getting angry and not paying attention to what people are saying. I've already said it is possible to have different currents at each end of a loading coil. And there phase information in those standing wave current magnitudes. There is no phase information is standing wave current phase. What I disagree with you about is you seem to attribute that difference to some magical property related to the distribution of current based on electrical degrees the loading coil replaces or standing waves, and that is very simply and clearly wrong. No, it is your misconceptions about standing wave current that are very simply and clearly wrong. Current cannot "drop" or be "dropped". RF current drops with the attenuation factor, just like RF voltage does. Clinging to the lumped circuit model presuppositions is what causes you to make silly assertions like the above. Standing wave current periodically drops to zero in unterminated transmission lines. The single thing that allows an inductor to have a current difference and phase shift in current along the coil or at each terminal is the capacitance of the coil to the outside world. Is capacitance to the outside world also what allows a wire to have zero current at one point and two amps of current 90 degrees away. Of course not! The degrees of delay through the coil is primarily responsible for the difference in current. That, and where it is places on the standing wave current curve. You have to include displacement currents in any model, or you cannot have a current taper along the length of a conductor. We are talking about displacement current to earth ground and there is zero displacement current to the outside world ground yet there's SWR current taper on coaxial transmission lines. Maybe it's time for you to learn how to add phasors? Sure. His explanation of what is happening and the fact he picked a very special conditions just to satisfy a twisted theory. Roy showed in his models why Cecil's conclusions were wrong. Practical measurements will show the same thing. Roy used standing wave current phase to try to measure the delay through a coil. That's an invalid measurement. None of my conditions are special. They just seem special to your lumped circuit model. The distributed network model works for all conditions. -- 73, Cecil http://www.qsl.net/w5dxp |
