 Power Adjustable Wifi and Cell Phone Signal Jammer with In-built Antennas WT-52K8      

      We had a lot of inquiries from our customers for the last couple of years. They all asked for a jammer which can jam all cell phone frequencies and can be mounted to the wall in their office and meeting room. School directors were asking for a jammer which can be mounted to the wall in the classrooms and exam rooms to disable the cell phone usage of students and let them concentrate on studies. At last we are able to offer you a mountable mobile phone jammer which can jam all cell phone frequencies of GSM, 3G, 4G Wimax, 4G LTE and WIFI/Bluetooth frequencies. WT-52K8 can be used worldwide and before shipping we always double-check cell phone frequencies in your country and make sure the jammer is configured to block them all.

     If you don't want to mount this jammer to the wall it is still fine to use it as a desktop jamming solution. The jamming range will be approximately the same.  WT-52K8 Cell Phone Signal Scrambler has 2 cooling fans inside which can prevent overheating. So basically you can use it for 24/7. 

    The buttons on the side of the jamming device can allow you to adjust the output power of each frequency band. If you do not want to block one band, you just simply turn the button to the minimum to turn it off. 

     Inside antennas of  WT-52K8 Cell Phone Signal Scrambler are all directional. The directional antennas comparatively have longer jamming distance. And also less interference to other devices.
