I am watching the Nat Geo show on EMPs and it got me thinking. If you have created a Faraday Cage what do you put in it? Cell towers and systems may not work so a cell phone won't help. I guess a radio may be useless as well???? My first thought upon watching this show was to buy or build a cage in my prep room with a two way and a cell in it. Now I am not sure what you should keep? Laptop, VHF, cell, ham? I defer to you who know a lot more than I.
