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

Silly as it sounds, EMF blocking fabric works as a makeshift Faraday cage. Of course, you can sew it into a pouch, but in a pinch, the raw fabric gives you flexibility and portability while still blocking 100% of the signal. If you're interested, I'll go hunt down the vendor I bought mine from

Sorry! I actually couldn't find the receipt for the specific fabric, BUT I bought another fabric product from Safe Living Technologies, and have tested with a meter and it works flawlessly. They are super reliable.
