Do you mean that since the length is infinite there is no reflected wave? But then here it is, once again, one of the most controversial issues... Yep, it's my digital logic in action. :-) If there's no end, then there cannot be reflections from the ends. And please note that I am not saying that the characteristic impedance of a dipole is constant all up and down the line. I'm only concerned about the apparent characteristic impedance at the feedpoint, i.e. Vfor/Ifor. Consider an open circuit transmission line. At 1/4WL, it exhibits a very low impedance. At 1/2WL it exhibits a very high impedance. As the transmission line length is increased to infinity, because of losses, the "stub" impedance will spiral into the Z0 characteristic impedance point. A similar concept should apply to a dipole. -- 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 =---- |
