Here at my listening post in SE Kansas, every spring & summer we have to 
deal with thunderstorms and lightning.  I always unplug antennas when 
there's a threat of a thunderstorm and so far never had any problems. 
Of course I've never experience a close or direct strike, and hopefully 
never will.

My 140' random wire stretches between two trees, and at the feedpoint I 
have a 9:1 balun which discharges static charges directly to ground.  I 
also included a spark gap for near strikes or high voltage charges.  Of 
course this won't protect against a direct strike, but will protect 
against static buildup from rain or snow.  And of course the 9:1 balun 
helps the impedance mismatch between the 50 Ohm coax and the high 
impedance of the wire.
