Maybe it's the same as the parallel tuning coil installed
at the base of a 75m mobile antenna which has a real part
equal to 12-25 ohms (depending on the quality of the antenna).

If you use an "L" network consisting of two inductors as a matching
device, the R must be less than 50 ohms. I was incorrectly modeling
the tapped coil as a two inductor "L" network.
