I wonder if an RF choke across the antenna and ground terminals might
give some protection?

My K2 (and I) took a small hit whilst at relatively great altitude in
ZS6.  At over 5000 feet storms creep up on you fast and I did not see
this one coming until it was almost too late. There was a crack; the K2
went completely dead and there was a small arc as I unplugged everything
and threw the antenna cable away from the K2. I escaped with a tingle
.... my xyl would perhaps say my thick skin helped. 
But unlike a well-known and much more expensive Japanese rig in similar
circumstances, the K2 came back to life after being switched off for a
few minutes. Power diodes are evidently very much tougher than PIN
diodes ...
(My host's Japanese radio has had its front end done in at least twice
now by static discharges ....) Good luck --- John G3JAG
