yes we are usually in agreement, which part do you not agree with, is it because i used such a long coax or do you not agree that the transformer action of a mismatched coax in a typical install does not effect vswr?,
i see no relation between transformer action when the load is reasonably near to the coax characteristic impedance and vswr along the same line in a typical install although that idea is often claimed on forums,
it is my understanding that common mode currents on the braid are the true cause of significant changes in vswr with small changes in coax length such as when somebody claims their reflect is high and they are told to swap their 6ft jumper for a 3ft jumper and that seems to fix the vswr issue,
the three sources i posted, bird, mfj, w2du and others don't agree the transformer action effects vswr,
w2du says in his reflections that some writers incorrectly claim it does but i have not found the writers he is aiming that comment at other than what you often see posted on forums,
i have probably posted the same idea since i believed transformer action manipulated vswr at one time although i don't recall where i got the idea from,
its likely that i observed changes in vswr with coax length as most of us have and came to the wrong conclusion about the mechanism causing the change in vswr,
i fully agree that the impedance looking into a mismatched coax from the radio end changes with coax length and that an exact electrical 1/2wave of coax with no loss mirrors the terminating impedance, i don't agree that effects vswr in the same coax if the braid is free from common mode currents.
