Tatuo 1 Roll 1 Roll Faraday Fabric 79" x 42.5" Emf Shield Protection Emf Blocker Faraday Tape for Anti Radiation, EMI Isolation, Signal Blocking, WiFi Jammer

I really didn't expect this to work but it worked just as I needed it to. I have a very specific use case where I had my guitar preamp picking up interference from my WIFI router, causing a loud thumping that an ordinary noise gate cannot eliminate. At first I thought it was the tubes so I swapped a few times but nothing worked. Through process of elimination I discovered the router was the source of the interference. I took a flier on this as it was cheap enough to try and low and behold the noise went away as soon as I put the material on the side of the rack that faced the router. Eliminated the issue immediately without any fiddling. My use case is very specific but it may help someone else with their issue and it was cheap enough to give it a try.

The Best Value DIY Grounding Sheet Ever! 👍My wife and I don’t use this fabric for EMF-Shielding.Faraday Fabric is very conductive, so it’s excellent for Earthing~Grounding. This sheet arrives pretty stiff, but looks and feels like soft, golden silk after just a few nights.Typical grounding sheets cost around $30 for a 27x52 inch piece, but just have a grid of 3 or 4 silver threads per inch woven into the fabric.This Faraday Fabric is Over 6-½ Feet Long and 3-½ Feet Wide (79”x42.5”)and has a continuous micro-weave of COPPER– a Superior Conductor! So, at $13.99, we got a sheet that is about 3 times bigger but less than half the price!!🙌🏼✨🙌🏽 We’re buying a second one today!!

I literally did a test with a EMF measured and IT WORKS!!!! I rent a partially furnished apt in there are some huge speakers from the 70’s in here. I purchased these to lay over the front of them in which the EMF levels were high, put this over that area and it literally lowered it. Thanks!

First off, the material is relatively thin, but seems to be of a descent quality. Looks shiny like copper, and the resistance measured with an ohm meter between various points is less than .1 ohms. With the wifi turned off (to prevent any compensation in signal strength by the routers), I used the Ubiquiti WiFiman android app to measure the attenuation with the fabric placed about 18 inches feet in front of the phone. On average, there was a 10 db drop measured against three different Wifi access points. In the end, I folded the fabric in half (doubled it up) and hung it in the attic about 18 inches behind my TV antenna to reduce the EMI on Digital Channel 13. It actually worked, and the signal to noise ratio increased by about 5 db (which means less noise coming from behind the antenna).

I was excited to get this and so disappointed when it didn’t do a thing! I covered things around the house and tested it with my tester, no difference. My son and husband laughed and think I’m nuts for even trying it, but there were good reviews too. I actually bought a different one at the same time and sent it back too! I got to get over and give them a bad review too. Sure wish it would have worked though!

The emf reading in my bathrooom that was opposite the wall where my Wi-Fi modem sits read very high, so I cut a piece of this fabric and tacked it on the wall by the modem. Voila!! It brought the reading down by about 80%. It is well worth the price. Hope this review helps.

The thin fabric works extremely well. Had a friend try to call my phone and no signal went through. Exactly what I wanted.

So I tried the putting my cell under a piece and calling it and it worked. No phone call. I plan to put in my purse and on my cell and over my wifi. There's plenty of it to do tons of projects to protect yourself. :)
