I say it's 50-50 whether it's a high impedance or low impedance at the coax connection point. We don't know how long the open wire line is so the high SWR line could have rotated to anything that would produce that particular SWR.

True - but in the situation being discussed the high SWR on the short
length of coax is being caused by the load at the balun/ladderline.
Arguably that high SWR is more likely to be a high impedance mismatch
than a low impedance one.

Of course, many short 160 meter antennas have a very low Z, and thus this
case is not relevant, but that doesn't keep Steve's assertion from being
correct, and worth keeping in mind--SWR isn't the whole picture.
