Re: [TCML] Interesting Coil Wrap

["David Rieben" <drieben@xxxxxxxxxxx>]

Hi Ryan,

Sounds an awful lot like a bi-polar coil ;^) Both ends of the
secondary coil are "hot" and neither end is grounded. They are
wound in opposite directions so that the two hot ends of the
secondary are 180 degrees out of phase and will spark towards
each other. This requires twice as much secondary wire as a
standard single-ended secondary coil but does have the ad-
vantage of not needing a dedicated RF ground.

Hey Everybody, I recently saw a diagram on the internet of a person using a 
different coil wrapping style for his secondary.  It went something like 
this.  Imagine a secondary coil winding that starts in the middle, instead 
of one end to the other.  THis person took their wire, folded the length 
they wanted to use in half.  From the middle of the secondary, they wrapped 
half of the wire length in one direction and towards the bottom.  Then, they 
took the other half of the wire (the un-used portion as of yet) and wrapped 
it in the opposite direction, and towards the top of the coil.  My question 
is:  What would this be used for, and, would it actually work as a 
secondary?Ryan_______________________________________________
