Ding,(just chiming in!),

I'd be very interested in knowing what the input power to Mark's 
system was when it created 18 foot streamers.  That 22 Ga. coil had a relatively
long aspect ratio giving a long air path from end to end, and the wire used had
considerably more insulation than usually employed.
Both these factors should  allow for considerable input power without self-
destruction from breakdown.  Mark is being modest, 18 foot streamers 
are SOMETHING to be proud of, even if you did use a nuke to make 
them.  C'mon Mark, inquiring minds want to know!

Happy coiling! rwstephens
