Having witnessed firsthand what lightning can do to a completely unprotected station, I decided to do things differently when the time came to rebuild the Excalibur Site.
The following photo is from a lightning strike that entered the shack five years ago via a balanced feedline. There was no grounding system in place, so the lightning energy flowed through a wall stud and an ARRL Antenna Handbook on the book shelf on its way to ground. The wall stud burned almost completely through, and the thick handbook was turned to fine ash. The building was subsequently dismantled.
