By claiming he puts the E and H fields in phase, he forces the ExH power flow vector to be equal to zero. :-) -- 73, Cecil http://www.qsl.net/w5dxp Yeah, Cecil, that's what I thought, too, but not according to Ted. He puts his antenna up at 1/4 wl above ground and gets 2.25 dB gain over a standard 1/4 wl vertical. What am I missing here? Perhaps we just haven't yet found Ted's secret for squeezing the E and H fields to rest on top of each other instead of in sequence. Walt |

The only possible conclusion is that he doesn't put the E and H fields in phase. Could it be that there is another dimension, in which the EH antenna operates, which allows ExH to be greater than E*H[sin(90ΒΊ)]? - that's 90 degrees for you incompatible nerds. :-) -- 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! =----- |

Hi Walt,
What you are "missing" is that the EH antenna can be made from scraps of PVC pipe and used aluminum foil. Don't need no stinkin' steel towers. (Except as "support" of course.) Don't worry about whether it works or not; it is a great recycling project. 8-) 73, Gene W4SZ Walter Maxwell wrote: Yeah, Cecil, that's what I thought, too, but not according to Ted.
