| What you're talking about is called a Faraday Cage.
I think you have the right idea, except instead of foil, you are supposed to use copper mesh screen. Some sources recommend that you tie this cage to ground.
The aluminum foil is for lining the inside of your hat with. 
Do a search for "faraday cage" and you will find plenty of info. |
