I got rid of my Boonton Q-meter years ago because it was a boat anchor and I couldn't lift it. Still, that was perfect for this sort of thing.

I am afraid that this instrument do not qualify because 50KHz cannot be considered as high frequency. If 50KHz is ok, then better get new DER EE DE5000 RLC meter. Today plain Q is far from enough, especially if you want to know specs at/around working frequency to stick them into Spice. You better look for proper RF impedance meter then. Thou OP did not tell much details - about why he is interested just in the Q and what he consider as "high frequencies".
I'm interested in LNAs and preselectors, and filters. And antennas, all sorts of antennas. For HF I am particularly interested in loop antennas but pretty much all antennas at all frequencies from LF to microwaves interest me. Also I am interested in antenna tuners.
I have built a lot of disposable antennas to see how they work.
Frequency independent antennas especially, are forgiving on exact dimensions and materials, generally, as long as you get the angles right. So they are pretty experimenter friendly.
My success up until now has been mixed, but when its been good its been good enough to make me want to learn more.
