"avid readers of mine" lol.
Caduceus coil practically consists of two coils wound in opposite directions. Their magnetic fields cancel out and so most of inductance is eliminated.


Magic ends there.

Have to admit I had to look this up as hadn't heard of it before. As Alan suggests, don't think it will perform well. But.. there's only one way to find out. Let us know what you find with your 70cm experiment.
