"Calltrex" wrote in message ... "Cecil Moore" wrote the message the antenna must be reactive ! From your explanation at 180 degrees, why doesn't current at the right side flip over then ? Should be. When all the voltages and currents are either in phase or 180 degrees out of phase, the resulting impedance is purely resistive. There is *no reactance* in an ideal resonant dipole! -- 73, Cecil, IEEE. I agree that the antenna is a chain of different pure resistances. But that doesn't explain the asymmetric 'snapshot' here. At the left side we see '+' voltage and '+' current and at the right side we see '-' voltage and '+' current ! Why should it be asymmetric? When i put a car battery with the plus on a lamp i will see a minus current ?? Hi Calltrex Now I see your situation. When you want to see the current meter read plus instead of minus, reverse the leads on the current meter. Then, when the voltmeter reads plus, the current meter will also read plus. Jerry KD6JDJ |
