Hi Luke,

I just thought of something that may or may not apply here.  This is in the
context of sailing boats and lightning protection from a metal mast.  A rule
of thumb is that the mast provides a 45 degree cone of protection.  So I'm
wondering if this same 45 degree protection would apply for a corona ring.
That is, if the ring was 2 inches above the top turn it would need a radius
2 inches larger than the coil form.
