You assertions have to be valid for all cases or else they are invalid. Finding one special case that agrees with your assertions, e.g. your previous toroidal coil measurement, may boost your ego but doesn't really matter one iota in the overall scheme of technical fact. -- 73, Cecil http://www.qsl.net/w5dxp Actually that statement proves YOUR theory wrong Cecil, not mine. I'm saying that in an antenna of fixed length with a fixed coil location on a given frequency, I can change ONLY the coil design, still maintain resonance, and have phase delay of current change significantly. YOU are the one who appears to be saying all coils and stubs are equal within a small range. The theory I believe to be correct is the capacitance from the inductor to the rest of the world compared to termination impedance determines phase shift in current and current taper. What is it you think determines current phase shift at each end and current taper? Explain the logic behind your idea in a way that makes the toroid work, or a compact equal form factor inductor have very low phase shift compared to an entire helice. My example works in every case. Your's fails, and you cannot just toss out the obvious disagreement and expect people to take you seriously. 73 Tom |
