Hello from one of the lightning centers of the 
world.  I run a 4L SteppIR, the tower's been hit, 
lost a couple of ICE protectors (graciously 
repaired for free by ICE), and everything still 
works fine.  My installation is at:

Click on Ham Radio, then SteppIR or Lightning Protection.

Not sure there's anything that is 100 percent 
lightning proof.  I run protectors on the cables 
to, from, and at the tower, grounded the coax 
shields to the tower at the top and bottom, and 
all the other stuff routinely used to try to 
persuade Thor's Hammer from doing damage.  YMMV

Sounds like you're going to be in a great location for DX.

Happy Holidays
