Barry, W9UCW has done extensive measurements using termocuples and other methods minimizing disturbance to measured system. He found that current in (esp. longer) coils is diminishing towards the other end. If you add 1/4WL to the top of the antenna, the current in the coil will *increase* towards the other end. In a standing wave antenna, the total current is the sum of the forward current and the reflected current. Whether the total current increases or decreases depends on the phasing of the two currents at the point where the coil is placed. -- 73, Cecil http://www.qsl.net/w5dxp -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 80,000 Newsgroups - 16 Different Servers! =----- |
