Re: Maggies & their schematics

>From the ASCI diagram I can't tell for sure. You only need a normal primary
coil and a normal secondary coil --- not 3 coils. You place the normal sec
coil approx 8 ft away on elevated stand. You feed the bottom of sec over to
a moveable tap that attaches onto existing primary coil. With a pole pig
this normal primary would have inner end grounded. The series cap feeds the
moveable normal primary tap. The only difference is you moved the normal
secondary coil and now need to connect it into the normal primary coil to
feed power to it. It becomes a series resonant inductor. Works very
nice --- be sure to have a lot of primary turns ---- even with scrap wire so
you can experiment over a wide range of taps until you get it right.
The advantage to this system is the primary can be completely enclosed in a
plastic box with a single feed line coming out. Feed should be very low
loss like 00 ought welding cable.
