Interesting.  I wonder if there might be a similarity there?
Anyone have any thoughts on this and also can someone direct me to where
more information on the sailing mast protection can be found?

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.
