If you are technically correct, why are you so technically silent on the subject? I'm not silent. I think I've done a good job of explaining things, and I've made measurements and posted results. At least a dozen of my technical questions have gone unanswered by being ignored. Lot's of readers have noticed and commented in emails to me. So what? 1.) I told you weeks ago I'm too busy working right now to get deeply involved in this. 2.) When measurements are made, you dismiss them as "measuring current in a system with standing waves". If you will repeat your measurements with 1/4WL added to the top of the base-loaded mobile antenna, you will start to understand the physics involved. The current taper through a coil depends upon where in the standing wave environment that the coil is installed. Then why can I measure a fixed inductor location in a dfixed antenna, and range from no taper at all in current to just under 1/3 reduction in current? Does you standing wave model explain this very repeatable measurement? http://www.w8ji.com/mobile_antenna_c...ts_at_w8ji.htm The lumped-circuit analysis fails for the typical 75m amateur radio mobile antenna. I disagree. Unless we want to say so does the standing wave model. The antenna can be modelled as a series of lumped inductors with capacitance to the outside world just as well as any other method. 73 Tom |
