If you live in a place where lightning is a problem, then protecting your equipment is a must. You would also need a lightning rod at the highest point near your house. Maybe this is your house or it could be a windmill or some other structure. But either way, you would need a metal pipe or rod at the highest point and pretty big wire going straight to a ground pipe. But even with a lightning rod, if lighting strikes on your property, then a huge static charge would still be in the local area. This could travel through your shortwave antena wire or power cable from your windmill and fry your expensive circuits.
