1 Roll Faraday Fabric Emf Protection Rf Blocker Anti Radiation

I tested this material for RF omring from wall out and it was still high. Not good for protection. Sorry.

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.

Thanks to this product i've gotten the best sleep of my life. It's kept the government and all of my noisy neighbors that were harassing me via super frequency waves out of my head 10 out of 10

This really works in protecting from emf. I cover my electronic gadgets and phone at night and this helps block any radiation.

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!

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).

Excellent seller and excellent product!!!

Use this fabric to line a wooden box to store items I want to protect . Just in case!
