Aluminum Foil Faraday Bag. Aluminum foil does block or shield radio frequency waves. Wrap the box in heavy duty aluminum foil at least two layers.
Aluminum foil does block or shield radio frequency waves. Team Clark wanted to see if it really works so we wrapped one piece of aluminum foil around a key fob and tried to unlock a car from about 10 feet away it didnt unlock. If during your test you would have grounded your trash can with an old piece of copper waterpipe or a ground rod the grounded trash can and the cardboard insulator would have blocked out virtually all RF aluminum foil is completely unnecessary.
The thickness of the Mylar bag is 35 mils.
Certainly you can stack multiple Mylar bags in order to achieve results that are similar with those you get with Faraday bags. If during your test you would have grounded your trash can with an old piece of copper waterpipe or a ground rod the grounded trash can and the cardboard insulator would have blocked out virtually all RF aluminum foil is completely unnecessary. When you do so be careful to isolate it completely. After all tin foil has been proven to dampen your key fobs signal but doesnt completely block it since the material lacks density.
