What I do is connect the choke across the output of a tuner to generate
a CM signal across the winding. Adjust the tuner for a good match to 50
Ohms and drive it from a transmitter. That way you have a
well-controlled experiment.
You can measure the CM voltage across the choke and the current through
it, or calculate them knowing the power output from the Tx.

It seems one could come up with a test fixture that is a bit more
