I thought it was common knowledge that the reflected energy is totally re-reflected in the forward direction when encountering the open or short circuit at the matching point. The voltages and currents are listed at the Z0-match point in the following example: rho=0.5 200W source---50 ohm feedline--+--1/2WL 150 ohm feedline---50 ohm load Vfwd1=100V-- Vfwd2=200V-- Ifwd1=2A-- Ifwd2=1.333A-- --Vref1=0V --Vref2=100V --Iref1=0A --Iref2=0.667A Vref1 = Vfwd1(rho) + Vref2(tau) (this is the same as b1=s11*a1+s12*a2) 0V = 50V at zero deg + 50V at 180 deg i.e. the voltages cancel Iref1 = Ifwd1(rho) + Iref2(tau) 0A = 1.0A at 180 deg + 1.0A at zero deg i.e. the currents cancel Through wave cancellation, both the voltage and current go to zero in the direction of the source. That's like a short for voltage and an open for current. -- 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! =----- |

Your failure to confirm or respond to Walt's second correction offers compelling further evidence that you are an unreliable correspondent. Actually, it confirms that I am a polite correspondent. Walt and I are discussing this in private email. -- 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! =----- |

Many say, "Take it to private email!", and you say, "Don't take it to private email." What is a poster to do? -- 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! =----- |

Admit your repeated public errors On Sun, 27 Jul 2003 00:33:47 GMT, "Walter Maxwell" wrote: Cecil, this is the error on Reflections that I told you about last week that have already been solved in private correspondence. Why do you make Walt come to this public forum to correct you for an error he has already corrected in "private" emails? You continue to support the evidence of not having read your correspondence from Walt, or ignoring it to offer a knowingly erroneous premise. This is unreliable correspondence at two levels. 73's Richard Clark, KB7QHC |
