faraday fabric 43"W×118"L(Big 3 Yards)

Bought this to cover my generator. Good quality.

Great fabric! Keeps out cold and if you live near a tower claiming to be a telecommunications tower it does reduce EMF. I purchased enough to put up 6 layers on every window and door to reduce EMF emissions.

I also bought the name brand fabric with the initials MD. The name fabric feels more like fabric and doesn't have as many stray fibers when cut, which may make it better for sewing, but this fabric did a better job blocking signals. In my unscientific testing (calling a cell phone that's inside the fabric from one outside of it, playing music over WiFi, and playing music to a Bluetooth speaker and placing the speaker inside the fabric) this fabric needed two layers rather than four of the name brand fabric to block cellular, WiFi, and Bluetooth signals from very close by (less than a foot away). I did need a layer of non-conductive material between the devices and this fabric and of course there can be no holes or gaps anywhere (the fabric needs to be fully and completely sealed to be effective). But it made a beautiful liner for my faraday cage along with some faraday tape and a gasket for the opening. Very happy to find fabric that is not only much cheaper and better for my purposes at the same time.

Aside from the completely laughable advertising copy, this material has a few good uses. 1) Small bits of it can be used to repair worn-out conductive rubber pads in remote controls. 2) It is conductive on both sides and measures very low resistance with an ohmmeter. 3) I bought this for a ham-radio "magic carpet" portable antenna grounding scheme. I added some tarp rivets in the corners for hold-downs. This package version also comes with some rather useful sticky Velcro pads. Want a good laugh? Read the advertisement. 1- Wrap your monitor up with it to reduce EMI....... so you can't see the screen???? 2- Wrap your cell phone to reduce radiated RF into your head....... so the phone's antenna stops working and drops the call??? 3- Wrap up your WiFi router....... to reduce it's range????? 4- Wrap up your laptop for EMP protection...... who's Internet provider is going to work after the big bang???? 5- Wrap up your desktop computer....... so it overheats and fries????? 6- Wrap up your Echo...... yep it may disconnect, but it won't mute its microphone, if you care. 7- OK you can make a decorative curtain out of it. Its nice and shiny. But there's cheaper alternatives. The only one that makes any sense is a wallet wrapper. This might actually prevent card probing.

Works well. Wrapped alot of stuff.

I was not able to get as high of a yield as they indicated on site. I folded it many times and still was not able to get that yield. I would not expect this item to do much as draped over you.

These are used a variety of ways but I use mine in one, particular, way...as a ground cloth counterpoise in conjunction with my radio antenna. It's what some amateur radio operators refer to as a "magic carpet." The only negative feature is that the cloth is fraying. But, this wouldn't be a problem when used more conventionally as noted in the product description. I could easily remedy this with some duct tape placed around the edge. I recently bought another.

You will need several layers to protect your electronics as this fabric is very thin.
