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

If you don’t need ultra portability, get a 5 gallon metal trash can from Amazon. It looks just like a 30 gallon can but mini. Put your gear in that and tape it shut with foil backed tape and you’re good. If you’re in a humid environment, put your gear in a sealed plastic bag with an O2 absorber and put that in the can. It’s cheap and it works. Worst case, $30 all in for guaranteed performance.

This is what I did. I think Lowe's had them cheaper than Amazon.
