From what I heard you won’t find a real Faraday bag that works well and blocks almost all signals, those found on Amazon are really not that effective and only “military grade” bags could be useful in these kind of threats
I know but don’t think you could find them there. The only way of getting good ones is surely to buy some that seems reputable (aka not amazon shit) and test them in labs (maybe someone already done that and that Faraday bags recommandations exist online)
When talking about real and useful bags I’m talking about those that are blocking almost all the frequencies.
Putting a device in a Faraday bag means that it’s not safe at first so it should be able to block all frequencies not only “call frequencies”
I wonder if I could somehow manage to whip up an experiment using the spectrum analyzer on my flipper zero. I would have to push the button while it is in the bag.

Okay. That means I need to chexk the surplus stores. Maybe I will get lucky.
I don’t think that if real Faraday bags meant for military work they are avaible in surplus store for civilians
This is not bleeding edge tech.

You can always test, try calling your phone in different bags

Faraday bags pass through all frequencies smaller then the holes in the conductor.
If you want total blocking of all frequencies you need a solid conductive surface, i.e. a block of metal, or a bucket of ionized water.
So yeah, whatever you got, you need to test with the transceivers on the device.
But military grade is just gear porn marketing term, you can make a gaussian surface out of house hold aluminum foil for Pete’s sake.

If you wrap your phone in aluminum foil that should block everything right?
sure, as long as there were no holes at all.
Cell phone frequencies are 2-20 inches so you could have one inch holes with no issue.
Thanks for the explanation

You would need two flipper zero, one outside emitting on several frequencies and one inside trying to catch any frequencies from the outside one
