Toroid is a shorted turn. Higher the better until top turn shows corona.
Make a bunch of different length spacers to vary height. FWIW on my 6 inch
sec. pole xmfr driven coil, I ended up about 4 inches. The toriod's shape
determines this distance. It's always a lot of fun to hit em with more
power. James

Subject: [TCML] Toroid height
On my 8.6" coil I currently have the bottom of my 9" x 30" toroid mounted
2.3" above the top of the secondary winding. I seem to be getting good
performance with at least 7 foot streamers from a 4800 KVA pole pig and
ballast. I see no discernible corona at the top of the secondary. Would
there be any advantage to mounting the toroid higher?
