Hi all,

Having done a lot of measurements last year I was interested in this.
I went to that Nat. Geo. article and noted the toroid and the height
it was placed at. I also noted a similarity in the height and where
I scored the best Q's with my terminal heights.
    Q. - Would you mind quantifying what you found with reference to
this coil re terminal height placement?

Thanks,
Malcolm
