What you said was *objective and impersonal*, applicapable to anyone's measurements and also applies directly to Tom's earlier measurements. I don't believe that Tom set up a simple standing wave antenna and then tried to measure the phase of the standing wave. Maybe we should ask him. As I understand it, both Tom and Roy set up a simple loaded 1/4WL resonant *standing wave* monopole and measured the standing wave current at the bottom and top of the coil. EZNEC could have told them that they wouldn't measure any phase shift around the coil or anywhere else around along the antenna.. It's an easy mistake to make to look at the current displayed by EZNEC and picture that current flowing from the feedpoint to the tip while being 100% radiated in the process so the current falls to zero at the tip of the antenna. As we know, those are not the technical facts. The reflected wave is a large percentage of the forward wave. As seen from the graphic at: http://www.qsl.net/w5dxp/3freq.gif that standing wave current can have virtually any magnitude but has a phase that comes only in near-zero or near-180 degrees increments. I've been asking how to obtain phase information from a standing wave current. Nobody has answered. -- 73, Cecil, W5DXP |
