First, I have no idea what an AADE unit is. Second, I don't know
what a B&W 852 is either, but since you're measuring inductance, I'm
guessing its a switched tapped inductor.
Third, all of your measurements are low by 25-35%, indicating the
possibility of a systemic error (like a voltmeter that's off by
30%).
Fourth, ALL measurements are subject to the limitations of the test
setup. What you're measuring are fairly low impedances at the
frequency of measurement -- on the order of 180 ohms -- so you
should get "in the ballpark" results from a reflection-based
analyzer (like most antenna analyzers). Perhaps try to borrow one of
these and see what it tells you.
