My guess is that the conical shape would have one benefit. The
E-field shape created by such geometry would tend to repel the streamers
up and out, resulting in less chance of primary strikes. Aslide from
that, I can't see much advantage and I can imagine that the self
capacitance of the coil would be increased compared(and hence lower
frequency given all else equal) to a helical coil with the same length of
wire and a diamter equal to the place on the cone where half the wire is
above and half below that turn. I'm sure someone like Bart could analyze
such a comparison...along with mapping of the E-field to see if my notion
is valid. I don't have such programs on this puter.

The advantage of a conical coil is that it can contain more power
times potential) before breaking out than if a pure flat spiral or
solenoid coil were used.
Why? I thought that breakout was a function of the top load geometry.
So if you are trying to build a small coil to
handle the maximum power, the conical secondary is the way to go.
