With nothing more than an audio signal generator, an LCR meter and the physical parameters
of the loop in question, how do I measure its self capacitance and self-resonant frequency?
The loop is 1 meter square and has 25 turns of what once was an old printer cable, complete
with a drain wire and foil shielding. Yes, I made a break in the drain wire and foil at the top
centre of the loop, directly opposite to the feed point. It measures 1.8 mH. of inductance.
I did a Google search on the subject, but most of the sites mentioned using a 'scope.
