Assuming my measurement is correct,

Hi Dan,

Why not prove your measurement is correct?

You already know the reactance. Plot it on a Smith chart for your
line (that is what makes Smith charts useful). Does your 43 degree
rotation lead to resonance?

Contrariwise, put your line at resonance on the Smith chart for your
line and rotate 43 degrees, do you land at the black box's terminal
reactance?

If you are adding more operations than either ONE of these two, then
you are working hard at finding the wrong answer and doing your
measurement incorrectly.
