Hi,

Today, the "length of the wire" has been found not to matter as far 
as streamer length or anything.  There are a few who still think it 
is based on 1/4 wavelength or something, but I totally disagree with 
them as do most.

You want a coil say 4 inches in diameter and maybe two plus feet 
long.  About 900-1200 turns works fine.

The length of the wire is:

3.14159 x secondary diameter x number of turns

So a 4 inch secondary with 1000 turns uses 1050 feet of wire.  Much 
wire data is here in the back:

Also see John's notes here:

Cheers,
