Whatver you wind up the default is to not have the antenna connected when not listening, and do not listen during a thunderstorm. A nice big knife switch would work. That way hopefully you won't have to replace the antenna coil or your home. Gee 100 feet longwire would be great.

That being said, there are lightening arrestors which are spark gaps can divert a lot of problems from the antenna to a big old ground rod outside through a stout cable.

Of course a 2' X2' tuned loop inside is also surprising !
