ISTR a simple LC oscillator that, when coupled to a frequency counter,
enabled unknown/dubious inductors to be classified when oscillating
with a known Capacitor. Where did I see it?.
==============
Realising that not every ham has a MFJ 259B or similar analyser , this is a
really useful instrument and well worth considering ,not only for antenna
matching.
The 259B has among its facilities a capacitance and inductance measuring
capability.

When mesasuring inductances and capacitances it is very revealing that the
measured values do change dramatically at higher frequencies ,especially
useful to know when using components in HF and VHF circuits.

BTW I also use an inductance & capacitance meter with LCD readout
,operating with an internal 1000 Hz oscillator , which measures the
inductance / capacitance ,obviously at that frequency and is fine for up to
the lower HF frequencies.
