John - Outstanding information. That is what I was looking for. Since I posted I did find a couple of SAA2 videos and it seems to work just like the others.
Thanks for the help

Re: [nanovnav2] CMCs - MORE (BAD) INFORMATION
The silver doesn't help much for RF conductivity, but it is a LOT easier to solder to.
I'm kind of surprised that magnet wire broke down. Most magnet wire is good for a kilovolt or so, because motors

None of those in the table exhibited this behavior,

And the same measurement, with the scale adjusted to better show what's useful.
Clearly stray capacitance is an absolute killer in these CMCs.

Peter,
just for the fun of it, I measured the CMC I used in my homemade antenna tuner. For about 17 years I used this tuner with its CMC on the air, using a delta antenna resonant somewhere near 7MHz,

Re: CMC - I PROMISE FINAL.......FINAL.......NEW INFORMATION
Dave,
Nice list.
What was de S11 on all of these measurements? (S11 as SWR)
Especially interested in the measurements where the loss in dB is more than 0.5
