Product Description The 16 bands high power stationary signal blocker covers and blocks band frequencies of cellular phone,WIFI,Lojack,VHF&UHF radio.With the stationary type design,the signal blocker comes with a high output power,for supporting multiple signals blocking and a coverage that ranges from 2 meters to 50 meters. As a stationary signal blocker,it has an ability to keep working continually inside of a building or even in a vehicle (with car charger)You donâ??t have to take the problem of heat dissipation into your account,due to 2 cooling fans keep running inside to deal with the problem.
