The short answer is no to the question of the impedence being the same. though the current would be halfed in each line. I'm not sure that I have see a four wire open line in the past but if my memory is correct it fed two dipoles not one. An interesting article on such is "Quadro-Line: The Ideal UHF Transmission Line", ARRL Antenna Compendium, Vol. 3. It's four box-spaced wires in a parallel type transmission line. Two adjacent wires have a Z0 of 200 ohms. Paralleling the four wires yields a Z0 of 100 ohms. Choosing two diagonal wires yields a Z0 of 250 ohms. -- 73, Cecil http://www.qsl.net/w5dxp ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |
