There are several examples at Food for thought.txt available at http://eznec.com/misc/food_for_thought/. Regarding errors in the first food_for_thought: A 100w source equipped with a circulator and load while looking into an open line, will generate 100w and dissipate 100w in the circulator load. That 100w is definitely not free power. It can be demonstrated to have made a round trip to the open end of the feedline and then back to the circulator load. The error in your thinking is that the source would see an open circuit when it is equipped with a circulator and load. It won't. It will *always* see the Z0 of the feedline as its load (assuming the circulator load equals Z0). That's the purpose of using the circulator and load - to allow the source to see a fixed load equal to Z0. -- 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 =---- |
