I have an MFJ-269 which I can measure the input to the coax and get a
direct impedance measurement.

Then I would put the tuner in line with the MFJ-269 as the source and
adjust the tuner until I see 50 + j0 on the MFJ.

I would follow by measuring the pi-network components also using the
MFJ as it will measure values at the desired RF frequency.

I would keep the signal frequency low so that stray inductance and
capacitance do not affect the measurement.

What I would like to do is see by using the values I obtain, calculate
the cable load and compare with MFJ direct measurement.

I will review the handbook to see if there is a standard equation
knowing the values and assume that the Q of the inductor is greater
than 10.




All in the fun of the hobby.
