Cecil, you can be so thick. Do you inhabit the center of the universe? We've waded through this long ago. Is the above example in Chipman? No. He does have a snippet of math that will provide the same answer found for similar (differing only by magnitude of R's) examples by other authors. These issues are new only to folks here. Hi Cecil, It seems that whenever I challenge you to one of your comments such as: everything can be explained by achieving a conjugate match you fly from it to prove or question some remote issue. Instead of going over old material that you abandoned (and will only abandon again), why not simply offer the group the conjugate of: source=200 Ohm(resistive)---50 ohm feedline---load=200 Ohm(resistive) which was my query this time (or are you abandoning that too?). 73's Richard Clark, KB7QHC |

We've waded through this long ago. You cloud the issue because you refuse to answer simple questions. I don't remember what your answer was and I can't find your previous answer on Google. Is a simple "yes" or "no" too much to ask? Instead of going over old material that you abandoned (and will only abandon again), why not simply offer the group the conjugate of: source=200 Ohm(resistive)---50 ohm feedline---load=200 Ohm(resistive) which was my query this time (or are you abandoning that too?). If the lossless 50 ohm feedline is a multiple of 1/2WL long, the system is conjugately matched. Chipman says the extra power term only exists when the reactance of the feedline is opposite in sign to the reactance of the load but your load is purely resistive. So I don't know what you are trying to say. Therefore, I don't know whether to agree with you or not. -- 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 100,000 Newsgroups - 19 Different Servers! =----- |

So I don't know what you are trying to say. Therefore, I don't know whether to agree with you or not. Hi Cecil, You don't have to know as it is not a matter of agreeing, it is a matter of your statement offering: everything can be explained by achieving a conjugate match and I see nothing about that in a halfwave line that instead achieves a Zo match, not a conjugate. A conjugate has very specific properties and you cannot provide an expression that offers the conjugate for the situation: source=200 Ohm(resistive)---50 ohm feedline---load=200 Ohm(resistive) Hence, the generality you impart to Chipman, due to your limitations, reveals it is neither a generality nor is it necessarily even a derivation of Chipman. Your two pages of copy are 230-odd pages shy of understanding. Let's just juggle the notion of Zo matching out with a slight boundary change: source=200 Ohm(resistive)---50 ohm feedline---load=600 Ohm(resistive) What is the expression you offer to support your statement that yields the conjugate? Barring an answer, it follows your statement that everything can be explained by achieving a conjugate match is yet another in a long list of absurdities. Perhaps you should await Chipman's arrival (Waiting for Godot?) before continuing on. However, given the consequences of that arrival for others in this group, that could mean total abstinence in discussion as so many seem to read him in the closet and find themselves locked in a small, dark room. 73's Richard Clark, KB7QHC |

A conjugate has very specific properties and you cannot provide an expression that offers the conjugate for the situation: You conveniently trimmed off the rest of my statement. When the line is lossy, it is possible to achieve a conjugate match at a point but nowhere else. The requirement of a conjugate match for a lossy line is that the impedance looking in either direction is the conjugate of the other direction. That can be achieved at a single point in a lossy system, e.g. at the load. The rule that if a conjugate match exists at one point, then a conjugate match exists at all points, is *ONLY* true for lossless systems. Let's just juggle the notion of Zo matching out with a slight boundary change: source=200 Ohm(resistive)---50 ohm feedline---load=600 Ohm(resistive) What is the expression you offer to support your statement that yields the conjugate? Barring an answer, it follows your statement that everything can be explained by achieving a conjugate match ... Again, please note that you deliberately snipped the context of that statement, not a very ethical thing to do. is yet another in a long list of absurdities. Well, since you changed the contextual conditions away from a possible conjugate match, nothing in the new example cannot be explained by achieving a conjugate match, since a conjugate match is impossible in the new example. What do you think changing the context proves? Nothing that you have said is true at the center of the sun. How's that for a context change? -- 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 100,000 Newsgroups - 19 Different Servers! =----- |

Nothing that you have said is true at the center of the sun. How's that for a context change? Hi Cecil, About average from you except this time you offered no solution for either context change. As such, it appears your statement everything can be explained by achieving a conjugate match ... has no meaning outside of the center of the sun. I will leave that you cannot demonstrate your statement anywhere in the known universe. 73's Richard Clark, KB7QHC |

None of my statements has any meaning outside of the context in which they are offered (which you conventiently attempt to obscure). It appears that you do not want to resolve anything. If so, I hope you won't mind if others resolve your technical problems at the very time that you are 100% resistant to any resolution. -- 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 100,000 Newsgroups - 19 Different Servers! =----- |

Your response of a Zo match is an embarrassing example of poor application for conjugation, so it would appear that even your single context is meaningless. 73's Richard Clark, KB7QHC |
