Yah. He called it the Jar and it was made of grounded chicken wire. The concept was the same, but the reason he built his was different. His was to prevent signals from his equipment from getting out and being picked up.

Faraday cages block EVERYTHING, which is why you need an external antenna for your radio...which compromises your protection from the cage...unless you have a surge protector somewhere in line with your antenna (it would have to be inside the cage as any wire outside the cage would stll pick up the pulse.

A multi stage "lightning arrestor" similar to what they use in the electrical power industry might do the trick, but it would have to be ALOT more sensitive to stop a pulse.
