In the past, I normally have always used a balanced tuner on my

those SGC antenna couplers, is NOT balanced..... It did not occur to me
that the currents through the twin coax feedlines to the balanced
antenna would not be equal. So, to make sure I am understanding you
correctly, this un-symmetrical current could also occur in open ladder-
line?

Yes, that's correct. I suggest taking a look at the article I posted the
link to -- it discusses this in more detail.

Obviously the weakness of my antenna knowledge has been exposed. My
thanks to Roy, AND to Owen.

Glad to help.
