The MFJ does NOT display the sign. But, I don't find this to be a
problem because decreasing reactance with increasing frequency is
CAPACITIVE and increasing reactance with increasing frequency is
INDUCTIVE.

Hi Dave, The MFJ-259B manual states this is "usually" the case, and that is
what I always do. Usually and always are not exactly the same. I do seem to
remember this discussed a few years back, and someone provided evidence this
was not always the case. They quoted Smith Chart proof. For the life of me I
can't find the thread, and haven't had time to play with the chart to confirm.
This method always (so it seems) works for me, but there are always exceptions.
