Or more precisely, the amplitude of the mathematical superposition of forward and reverse traveling wave currents in a half-wave dipole antenna varies inch by inch. It is the EM fields produced by the traveling wave currents that in fact superpose. Of course, I was referring to *net* current which is a superposition of forward and reflected currents, or H-fields if you prefer. The bottom line is that if magnitude and phase vary inch by inch in a straight piece of wire used in a standing-wave antenna, are we to believe that the variation can be reduced by adding more wire, just in a spiral? Did you notice W8JI changed his web page? The once outrageous statements have been considerably modified. I've noticed fewer of them on your web page as well, Cecil. Perhaps the world is coming to equilibrium. :-) My web page problem is the definition of the reflection coefficient. RHO and S11 have different definitions. Stand by for an explanation that even you can understand. :-) -- 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! =----- |

My web page problem is the definition of the reflection coefficient. Great. I'm interested to read it. RHO and S11 have different definitions. Do you remember when you and I talked about that? Stand by for an explanation that even you can understand. :-) That's the best kind! :-) 73, Jim AC6XG |
