This is based on how many degrees the signal has changed at the antenna input by the time the signal reaches the tip end of the antenna. When signal reaches the end of a 1/4-wave whip, there is an abrupt discontinuity. Only displacement current flows without conductors. The tip of the whip accepts only a small fraction of the current available in the forward power traveling on the whip. The only path for the rejected power is back toward the feedpoint. Direction and phase of the current reverse in the reflected power, but the voltages of the incident and reflected waves have the same phase (see 1955 Terman, page 89). Thanks Richard. I'm digesting that now. Let's see it any of it sinks in ! - Mike KB3EIA - |
