I see 1A at the base of the coil increasing to 1.07A at the centre of the coil and then dropping to 0.69A at the top of the coil. FYI Steve, five years ago I showed Roy how to estimate the phase shift through the coil using ARCSIN(0.69) = ~46 degrees. To this day, he refuses to acknowledge what EZNEC is telling him about current on a standing wave antenna which is: A current phase measurement on a standing wave antenna is meaningless. Here's a couple of graphic that illustrate what I am saying: http://www.w5dxp.com/coil.gif http://www.w5dxp.com/phasor.gif These graphs are very close to your measurements above. -- 73, Cecil, IEEE, OOTC, http://www.w5dxp.com |
