Faraday Cage Sleeves

[Lightspeed]

I store radio equipment in biscuit tins as per Devonian's recommendation. Test of functionality is as per what he said too. For me this is long term storage.

I think you'd be better off trying to find a small metal tin that will take the phone you want to protect. Alternatively buy one of the cheapo bags, put a turne's on and network connected phone into it and try ringng it..... if it rings the bag is useless, if not, its doing its job.

I agree with MB though, if there was an EMP that would knock out your phone, it'd also kill the cell towers and most of the other mobile phones in the area. And most cars, televisions, network controlled utilities etc etc. In that situation, a still operational mobile handset would not be a valuable asset per se.

The only reason I'd keep phones in Faraday cages is if they are smartphones and I wanted to preserve their non-phone functions and memories
