Have you ever actually made one of these magical coils, Cecil? If you have, will you tell me how to do it? It ain't rocket science, Tom, and it ain't magic. Do you understand self- resonance? Every coil is self-resonant on some frequency. Build the antenna for whatever that frequency is. My Diamond 440 MHz mobile antenna uses a phase reversing coil to phase a 1/4WL element with the 1/2WL element directly above yielding a fair amount of gain over a single 1/4WL element. Did you read Wes' material? That .pdf file locks up my computer during downloading. I may need an upgrade to my Adobe Acrobat reader. -- 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! =----- |
