"What I would like to find out is the preferred method of lightning
protection (that is, shunting it to ground).  There seem to be two methods:
a spark gap, and a shunt coil"

For what it's worth, if you make the vertical a tad short, you can use
the shunt coil to match up to 50 ohms.

Hardly necessary to have SWR perfection, but it's so easy to do.

If you use a shunt coil this is probably the way to do it.    I
wouldn't want to let the voltage get high enough from static buildup
to fire a spark gap.
