Highly Conductive Copper Fabric Blocking WiFi/RF Anti-Radiation Military Grade for Radiowave Microwave, Electromagnetic Fields 78"x43" inch

You can buy this much of this at easily 5x the price, and it works just the same as what’s sewn into the lining of everything else that “blocks EMF”.

I was skeptical of this when I bought this, and I'm not sure the practical applications of this, but it does block radiowaves. My car is push start, so a wireless key. When wrapped in this fabric, the car does not recognize the key. I also tested with my cell phone, using bluetooth headphones. When wrapped in the fabric, cell, wifi and bluetooth all disconnect. I can see my screen through the fabric to see wifi and cell are disconnected, and the headphones disconnect.The key seems to be connecting the ends of the fabric, if I make a pocket with the fabric, the signal is broken up a bit, but it still connects. As soon as I complete the loop, touching the top of the pocket together, it works great and blocks all signal.

The fabric is definitely thin and you might need to combine a couple of different layers together before you begin to see any signal reduction. Different devices may be more susceptible to the RF blocking than others based on the wavelengths they operate on, so make sure to pre-configure your monitoring tools accordingly. Approximately 700 yards from my home, T-Mobile has constructed a new 5G tower and it was imperative that I cover my infant’s crib with this material on all sides except the top. 5G spectrum is highly untested and unregulated, so until more scientific work is done I must act proactively to fortify my home. Within 2 months of the 5G tower being built, I began to notice minor joint inflammation and all of the preserves from my garden began to rot inside of their glass JARS! Then a few weeks later, I was wearing my RF gear while mowing the lawn and I watched a large cougar climbing the stairs to my deck only to immediately drop dead next to my charcoal grill. The 5G waves are clearly toxic and humans and non-humans alike are suffering!

I lack the scanner to test the radio frequency penetration, but the WiFi signal was blocked when I wrapped my phone in the material. I plan to stitch my wallet with this material. Cost less and made by my own hands. Better than the current products on the market.

Im using this product for solar flare uT shielding. It is a central core and head shield for me. My Electromagnetic Meter has gone off the charts twice with readings (in 3 hours to fifteen minute intervals) from 400-730 uT... At which period I quickly put on my shielding gear...and the ringing in my ears, nausia, trembling, and dizziness...stopped within 3 seconds. When my meter is put behind the Shielding...the Readings go back to 35-45 μT which is a normal reading and the machine stops screaming. I have also had my Tablet from Nook giving off a periodic high value (surge) up to 350 μT and stuck my head gear between the tablet and meter and the Meter readings went back to a normal reading...back and forth I tested this 5 times with the same results. For my purpose and feeling of Satisfaction...this product does work to shield from directional sources. I will be purchasing again. I suggest you do the same and create shields for all your Loved ones.

I ordered to line wristlet that I make for security from credit card fraud. My husband testosterone at work. It is not completely secre , cards can still be scanned through material , even doubled .. dissatisfied.

i used this fabric to make shielding pockets for cell phones and the keyfob for my car. Sews perfectly and works great. I suggest using tough utility scissors to cut the metallic fabric, not your nice dressmaker's shears which are intended for fabric.

when I wrap my phone in tin foil and call it, the phone goes straight to voice mail because the foil is blocking the cell signal. when I wrap my phone in the material that I purchased on Amazon, the phone rings, the cell signal is not blocked. This material does not block EMF's.
