## Description

Blocwifi is the best screening fabric for many reasons, not only does it cover the broad range of high frequency radiation but when grounded it is a fantastic low field blocker too. Please see the picture setting out the attenuation which I'm sure will please you. It is made from polyester, nickel and copper and lends itself well to under bed protection, blinds and curtain backing. It can be sewn. It is very strong and durable.

## Features

- About this item
- This durable fabric shields from TETRA and 4G at 82.4 dB and blocks higher frequencies such as wifi at a pleasing 92.5 dB - see pic
- Suitable for curtain backing or making into a roller blind
- When grounded it shields from low fields too
- Can be sewn, Not washable, wipe down only
- Multiple units ordered, shipped uncut

## Customer Reviews

    It does not work!
  

*by J***R on Reviewed in the United States on November 26, 2018*

Beautiful material, but does not do block any signals. My mom is very sensitive to wifi and she has a meter that she uses to read how strong the signal is around her. I was very hopeful about this product and we held it up in front of the meter and there was no difference. I'm very disappointed. I had no intention of simply buying a small piece of fabric for $30.
