Why not do the right thing by putting a lightning arrestor like a
Polyphaser at the point where the coax enters the shack connected to a couple
of ground rods? It's not a lightning protection *system* but it should
protect your radio frontend from these static buildups.
This is probably the easiest option as well since it's at ground level
and you don't have to fool with the antenna.
Champion Radio Products carries ham-related Polyphaser products.
