160W High Power 2G 3g 4g signal blocker , WIFI Mobile Phone Signal Jammer Up to 150m

Signal Blocker Introduction:


For absolute jamming of any cell phone signal, there is no stronger or more efficient solution than this 8 Antenna desktop Cell Phone Jammer.

This high quality device provides you with 120 Watts of output power and 8 powerful high gain antennas to completely block all mobile phone signals within 150 meters(depending on the signal strength)


When complete cell phone silence is needed, this 8 Antenna Cell Phone Jammer can be turn off via the separete switch. With its 8 high gain antennas, you get industrial-strength frequency jamming that is powerful enough to disrupt all cell phone signals (3G, GSM, CDMA, DCS).


It also provides 120 Watts of output power that will even jam the strongest signals, which usually cannot be stopped by the lower 30-50 Watt versions.


With a working radius of up to 150 meters, this device can be used in any location and even mounted on the wall thanks to the mounting plate and included accessories. Just put it in places where a phone call would be particularly disruptive because silence is expected or needed, and you'll get instant, remote-controlled jamming. For example business meetings, legal proceedings, churches, hospitals, movie theaters, class rooms, etc.


Best of all, this 8 Antenna Cell Phone Jammer will not interfere with other electronic equipment in any way!

Signal Blocker Application:
For places as the library, the church, the classroom, the meeting room, and so many other places this 3G 4G LTE mobile phone signal jammer can be used. And for places where the mobile phones are not allowed to be used this high power cell phone jammer is also suitable.
Can customize these frequencies:
LoJack 173MHz, VHF, UHF, Walkie-talkie, interphone, 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,GPS L2, Galileo, Compass, Glonass, WIFI, Bluetooth, Spy camera, WIMAX, UAV, Drone, 5.8G,etc.

Important Notes for Jamming Distance: The jamming distances we mentioned on website are for customer's reference only. The actual jamming distance will be varied depending on the signal strength and the use location, etc.
