Xtreme Sight Line ~ Diamond Form Faraday Fabric ~ Interwoven high-Shielding Copper and Nickel fibers ~ Blocks RF Signals (Including 5G) ~ 54.5" Width by 1 Yard (36") Length

I brought this fabric to cover my lod desktop computer that was causing interference to my indoor digital TV antenna. I brought a new system later and no TV interference however the fabric helps to reduce cell tower 4 and 5 G signals to my room and made my Tinnitus worse. After putting up the fabric to bedroom wall, my Tinnitus became less bothersome.

I placed this sheet under my office window because my cat likes to sit there looking out the window when I work and the EMFs were high because the electrical runs there. After applying the EMFs were at an acceptable level. Good product!

seems like its good for what i wanted

Put it in a window between outside elec.meters and room to stop rf signal. It seems to have done what I required.

I use my 5G hotspot for internet. May change that soon! Wrapped my phone in 1 layer and lost signal. Tested 2 layers of copper infused bed sheets didn't loose signal. Copper infused gloves, didn't loose signal... I added a layer of this material to my phone case but since it is not a complete wrap, I still get signal, but hope to protect my phone holding hand.
