I assumed that would mean measuring the standing-wave current, but Jim introduced the notion of measuring travelling wave currents. A point of correction here. I believe you will find the notion detailed on Cecil's web page. Yes, the total measured current on a standing wave antenna is primarily standing wave current. The total measured current on a traveling wave antenna is primarily traveling wave current. Please see my last posting. He's a guy with a limited amount of time and patience honestly attempting to subvert the ridiculous by stating the obvious. Obviously, a 100 turn, 10 tpi, 2" dia 75m loading coil cannot have the 3 nS delay that W8JI "measured". Do you disagree? -- 73, Cecil, IEEE, OOTC, http://www.w5dxp.com |
