Well, he said "OUT of an unbalanced tuner" so I assume that's the
ladderline side.

Yes, and with a reasonable limit, the SWR on the ladder-line
doesn't matter. IMO, 25:1 is no problem for ladder-line.


Correct, a high SWR is not an issue for ladderline, but the guy was
wanting to stick an apparently 50 ohm coax balun right there in between
his balanced tuner output and that ladder line. I would think a high
SWR, with some TX power, in that device might not do it much good.
