... the system will have additional loss of less than 3 dB. And it works fine. So the question is: Is any part of the reflected power in the mismatch loss calculation included in that 3 dB of additional loss? The answer is 'yes' and whether it works fine or not is irrelevant to the argument. -- 73, Cecil, w5dxp.com |

If there is loss going one direction on a line, reflected power going the other way suffers loss also. The part about "works fine" was thrown in, not for you, but for those who might be horrified by a high vswr. |

Sorry, I misunderstood what you were trying to say. My fault for delaying my response. I should have looked back for the particular "read" post, instead of replying to the one "unread" at the moment. I was trying to add into the thread the figure 1 referenced. I look at it as showing that at high VSWRs, reflected power takes more trips back and forth through the line loss until the reflection becomes insignificant. |
