The Tall Router Guard is a “Faraday cage” made of a low carbon steel with rigid metal supports around the top and base. There is no need to ground the Tall Router Guard because the RF, radio frequency, waves your router emits dissipates in the mass of the Tall Router Guard. Faraday cages do not need to be grounded to block RF. Here is a link to our video that demonstrate Faraday cages do not need to be grounded to block the RF your router emits.
Thank you for purchasing the Tall WiFi Router Guard! WiFi routers emit RF, also called EMF, all day and night exposing you to the electric field. The Tall WiFi Router Guard is designed specifically for the tall square WiFi routers like the Comcast Xfinity, Apple Air and Spectrum routers. The Tall Router Guard is built to block approximately 85% to 90% of the EMF your WiFi router emits while still allowing you to use your router with your wireless devices.
