Farday Fabric Farday Cage Military Grade Conductive Material for Fabric Protection EM from Cellular Signal, WiFi, Bluetooth, GPS, Shields RF Signals 44"X108"(3 Yards)

Lot of material for the price. Seems to be high quality and is easy to cut to size.

I ordered the large, And I draped over my new Harley Road king wall in the garage. Basically for any electromagnetic pulse. Draped over the bike with a reflective bike cover and I went to start the bike with the key fob In my hand and I was unable to start the bike. So it does block any electronic pulse. This product can be used on other things also, but it actually does work

Wife sewed two of these together and, with the help of four elastic straps, we put this under our bottom sheet on king sized bed. Grounding function works, we sleep sounder and dream better. We noticed bottom sheet was dark. Held to light, we could see “copper corrosion” green. We launder at reasonable intervals, and laundry removes most but NOT all of the stain.

Material was good.

I use this cloth to act as a groundplane for my portable antennas. It is far easier to set up than running a bunch of radial wires out from the antenna, easy to pack up, and is highly effective.

This fabric was very thin. I had to double it over six times to block a cell phone. I returned this item.

Imp to have to protect your own body or throw over a smart TV

Even with a phone wrapped up tightly with multiple layers of this fabric (like 10 layers), and no holes, it was ineffective at blocking Bluetooth, Wi-Fi, or 4G/5G in my trials. I’m not sure how it has gotten such great reviews from others here
