An EMP ranges from 1 Hertz (1 Hz) to 300 MHz. Cell phone freqs start at about 380 MHz and go up from there.

So, put your cell phone in your faraday cage and call it. If the signal gets through, you're NOT protected from an EMP. If it doesn't, then you're good.

An AM radio is NOT good enough. Just because an AM radio won't play in your faraday cage, that does NOT mean your cage will protect against freqs higher than that.

A 9GHz cordless phone is an even better test. Put your cordless in there and call it. If the phone doesn't ring, you're WAY good.
