Current across the antenna loading coil - from scratch
Roy Lewallen wrote:
The constant phase with position (of an open or shorted line) simply means that if you froze time at some instant and looked at the angles of the rotating phasors representing the total current at each point along the line, you'd find them all to be at the same angle. They're all rotating. Yes, when I said standing wave current phase doesn't rotate, I meant with respect to the source current phase. At any instant in time, the phase of the standing wave current is unchanging up and down the line. Assume the standing wave current all up and down the dipole is of constant phase with no variation with 'x'. Roy, you used that current to try to measure the delay through a coil. How did you plan to measure that delay with a signal known to be the same phase not only at both ends of the coil but all up and down the antenna? -- 73, Cecil http://www.qsl.net/w5dxp |
