Cell Phone Reception Blocker RF Jamming Device For Mobile Phones 433MHz 315MHz
This 8 Band RF Jammer is more effective than 6 band Cellular Jammers, as the RF jamming is regulated with a omni directional jammer feature. or use directional panel antenna, This helps focus the jamming wave on desired areas only.
Long time will be taken to recall what you have though if you are suddenly interrupted by the mobile phone calls of someone at the meeting, to improve the efficiency and the quality of the meeting, peaceful condition of no phone calls is needed. In such condition, the mobile phone signal jammers can show their power, and this 18W High Power 3G Mobile Phone Jammer is suitable.
Since owning the desktop style and high power jammer is suitable to be used in the certain places. And designed with high power output the shielding radius is up to 40 meters at most according to the signal strength in the given place to blocking the signals of the CDMA GSM DCS PCS 3G these 8 frequency bands at the same moment when the device start working.
Affected Frequency Ranges:
CDMA/GSM 851-960MHz
DCS/PCS 1805-1990MHz

RF, 868MHz
Power supply: AC adapter (AC110-240V)
Operate time: 24 hours continuous
Total output power:18W
Jamming range: up to 40m, the jamming radius still depends on the strength of the signal in given area
Antenna:8 pcs ( Please fix the antenna follow the mark in the unit)
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.
Mobile Phone Signal Jammer 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.
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.
