When the length of a loading coil is short in comparison with the overall height of the antenna, certainly in comparison with a wavelength, the current into one end can be assumed, with negligible error, to be equal to that which comes out of the other end as with any other coil in an L,C,R network analysis. But Reg, why do you think they call it a standing wave antenna? Would you also assert that the current is equal when a coil is installed in a transmission line with reflections? If it weren't for reflections from the open ends of a dipole, the feedpoint impedance would be hundreds of ohms. It's the reflections that reduces the feedpoint impedance to ~70 ohms. -- 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 100,000 Newsgroups - 19 Different Servers! =----- |
