Hi Jerry,

Dave's comments are accurate and helpful, in almost every case.
But there is the possibility of a very substantial simplification here.

The Key Question: Do you need or want to operate your rig during
electrical storms?

If the answer is YES, then you better do everything Dave suggests--
and possibly a whole lot more. Praying a little might also be helpful.

But if the answer is NO, then you would probably do just fine
(with respect to antenna-specific risk) using the last suggestion only:

One of the best things you can do is to have some sort of easy-access
connector coupling, located outside the house (e.g. at the grounding
block). If a storm seems imminent, or any time you won't be using the
rig for a while, disconnect the end of the antenna feedline and toss
it away from the house.

The main thing to remember on this one is that the more CONVENIENT
you make your disconnect, the more likely it will be that you'll actually
USE it appropriately.
