Why would you need the antenna tuner in this case? Assuming your XMTR is 50 Ohms on the output: 100W XMTR--50 ohm feedline--+---50 ohm load Voila! A perfect match. No mis-matchlosses, and no need for a tuner. Yes, but a real-world antenna rarely has a 50 ohm feedpoint impedance even though it is resonant. The feedpoint resistance of a resonant 1/2WL dipole can vary from about 40 ohms to about 100 ohms depending upon its height above ground. And a resonant dipole won't usually cover the entire 75m band without a tuner of some kind. -- 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 80,000 Newsgroups - 16 Different Servers! =----- |
