Actually, you got it wrong, Cecil. It's -43 degrees, which means
if you wanted to make one it would be about 317 degrees. (Actually,
I got -46.613 degrees.) Maybe you can make a length using negative
degrees, but it's tough for me to do.

What you apparently don't realize is the negative sign
simply indicates the direction on the Smith Chart of
"toward the source". This is absolutely reasonable since
we are indeed going in the direction away from the open
end of the stub toward the mouth of the stub, i.e. from
right to left if the source side is on the left.

From -j567.128 ohms to zero ohms "toward the source" is about
43.4 degrees. From -j567.128 ohms to zero ohms "toward the load"
is 316.6 degrees. Your signs are correct - you just didn't
understand what they mean.
