120 Watt High Power Prison Cell Phone Jammers with 11dBi Log Periodic Antenna




120W GW-J50 is constructed inside a special metal enclosure prison jammers , incorporating an efficient "smart active" cooling system with incoming air filters, which enables the system to operate 365 days/24 Hours/7days continuously even in hot weather. Its secure design ensures that the prison inmates and unauthorized prison personnel cannot tamper with the safe and continuous operation of the system.

Each unit can jam up to six frequency bands simultaneously.
For the cellular phone jamming, only making the interference to the downlink bands,never disturb the uplink and make sure BTS normal running.


1. Heat sink designing combing with the fans to make system in a cooling status.
2. Antenna type options, directional or omni-directional antennas option.
3. Adjust the output power of the jamming modules by the switch.
4. ON/OFF each Jamming module or device separately.
5. Selection of antennas to provide more flexibility regarding jamming coverage.

6. Can customize these frequencies AM, FM Radio, LoJack 173MHz, VHF, UHF, Walkie-talkie, interphone, Wireless Toys , FM Radio, Remote Control, 27MHz, 49MHz, 433MHz,315MHz, 868MHz, 450MHz, iDEN, CDMA, GSM, GPRS, DCS, PCS, AWS, WCDMA,UMTS,3G,4G,LTE 700, LTE 800, LTE 2300, LTE 2600, GPS L1,GPSL2, Galileo, Compass, Glonass, WIFI, Bluetooth, Spy camera, WIMAX, UAV, Drone, etc.

7. (Optional) jamming Four band, Five Band, or Six Band, Eight Band, Ten Band.
