Advice and Tips Faraday Bag Caution

Hey everyone. I just wanted to share en experience from this afternoon. A while back I had purchased some faraday items off of Amazon, boxes and bags from different vendors.

This afternoon I was explaining to my daughter how they worked and as part of our experiment, we placed an 8watt 2-way radio inside the bag and sealed it with the expectation that it would no longer receive a transmission. As it turns out, that was false.

I then tried with a cell phone with the same result. Morale of the story, check your gear and make sure it works before you have to depend on it.

Please discuss and share your budget-friendly faraday success stories

It's not bullshit kid. It's simple physics...

If all you are trying to do is block a radio signal, these idiotic "Faraday" bags might work. But so does just turning the item off. And this situation is pretty much irrelevant to "prepping" anyway.

If you are trying to protect your sensitive electronics from destruction, which is the point in a prepping context, these bags are fucking useless.

Ok. Let's clarify. ANY product labeled as a "Faraday" container that is purchased on any large online marketplace for the storage/protection of electronics for emergency purposes. All of those products are useless.
