This Desktop Jammer is able to block the cell phone/smartphones 2G(GSM/CDMA)/3G/4G/WiFi signals, as well as the normally used VHF/UHF frequencies which are very common for walkie-talkie. Every antenna(frequency band) has a separate switch, so you'll be able to decide to block the unwanted signals while not influencing on other frequencies.
NOTE: This jammer is very powerful and can block frequency band as low as 70MHz, which is obviously even more advantageous than other 16 bands desktop jammers sold by other sellers in the market!

Power Supply: AC220V-DC12V
Jamming Radius: 2 ~ 50 meters - depends on the strength of signal in given area
Working temperature: -10℃ ~ +55℃
Continuous working time >=12 hours
- The effective jamming range is the circular area centered on the jammer, so please select a proper location/orientation to place the jammer, to avoid blind corners.
- The jammer should be placed at sites with good ventilation, and try to avoid being sheltered by big objects as well as strong electromagnetic source with strong heat, so as to guarantee the jamming effect and continuously stable working.
- Never put any other items on the jammer while it's working, otherwise the jamming effect will be influenced and damage may be caused to the main unit.
- When the targeted area is larger than the jammer's effective jamming range, we suggest multiple jammer be installed in the form of honeycomb to guarantee the jamming effect.
- Please disconnect the jammer from the power supply timely when the jammer is not in use, otherwise the normal usage of mobile phones will be influenced.
- While using at outdoors, please avoid water!
- When placed at outdoors or field, please add protection equipment to prevent mice, ants and other destructive animals.
- Please avoid corrosive gas as well as fluid, and guarantee proper dust & humidity prevention work, so as to reduce the aging of the inner components.
