2. The second antenna is electrically 3/4 wavelength long. This one illustrates how the current at the top of the loading coil can be greater than the current at the bottom of the loading coil. http://www.qsl.net/w5dxp/octcoil2.gif http://www.qsl.net/w5dxp/octcoil2.ez Why the 3/4 wave example? This is NOT what I had in mind. What I would like to see, is you take a 8 ft mobile whip for 80m. Start with a center load. Note the current taper. Then place the coil below the midpoint level. Note the current taper. Then place the coil above the midpoint level. Note the current taper. You should be able to find a configuration that provides max current at the top of the coil, if what you claim is true. I want to see max current at the top of the coil in the SHORT loaded 8ft mobile whip for 80m. Not a funky overly tall 3/4 wave antenna. I'd try it myself, but I only have the demo of eznec and don't have the segment capability. Then if you can see this happen in the model, I'd like to see it confirmed in the real world. If this occurs, then I might start to think what you claim holds some water. I'll reserve further comment until you can try this simple test. MK |
