The 2.5" coil is also a pure experiment (not too much theory went
into it). Basically, it went like: had tubing, wound as much of the
aerial rod type litz as I had onto it and .... Well, there was
always a reasonable chance it would be a goody. Right h/d ratio and
due to the covering on the wire, somewhat spaced, not that that's
necessary for litz. Just the way it went.
Why do I love just winding coils I wonder??
