RE: [TCML] Source for 1H air-core inductors

Greg,

What size shaft and ratio gear head do you suppose you'll need for
winding the secondaries? There's a reason I'm asking.

Subject: [TCML] Source for 1H air-core inductors

Hi All,

I can offer one potential source for 1H air-core inductors; two will 
come free with purchase, as part of the NLL Project.  ;)

Each of the NLL secondary windings will have an inductance just over 1H.
If desired, they can be arranged in series for 2H, total.  The 1H claim 
can be confirmed using Faraday's Law; secondary coilform dimensions are 
29ft dia, 105ft winding length, and 1.8" turn-turn spacing.   GL
