"Roy Lewallen" wrote in message ... Jim, it sounds like you're firmly in the camp that believes that a phase and/or magnitude shift will occur from one terminal to the other of a physically very small inductor. Physically very small.........what is that? Is it an inductor that behaves as if it has no physical dimensions? Does it comprise a coil of wire that has zero length? Perhaps you can also propose an inductor I can put at the base of a short antenna that would guarantee a large phase shift which would be large and easily seen in a measurement. How about if I just refer you to one of the many manufacturers of such things? 73, Jim AC6XG Roy Lewallen, W7EL Jim Kelley wrote: "Roy Lewallen" wrote in message ... I did read what you said. You said that it wouldn't exhibit a phase shift if placed at a current maximum. The current at the base of a short vertical antenna is at its maximum there. So now if you're saying that it *won't* exhibit a phase shift if placed at the base of a short antenna, let's try this. Naturally, the inductance of the coil and the resistance of the circuit determine how much of a phase shift there will be. But the amount of resulting change in current magnitude will depend on where on the cosine curve this shift occurs. A 10 degree phase shift from 40 to 50 degrees generates almost an order of magnitude greater change in current that it does shifting from 0 to 10 degrees. Obviously, the closer the center of the coil is to zero (or 180) degrees, the smaller the resulting differential in current across the coil. 73, Jim AC6XG |
