With the development of wireless communication technology, there comes a series of serious problems of privacy leak, especial in cell phone using. For example, attending a meeting with cell phone it may leak if the battery didn’t take out. Besides, it is a new threaten to gas station, oil field and oil depot, may cause fire or explode; a new rigged way be used in examination hall. So jammer/ blocker were invented to deal with the problems on above. It is a new security product. Forming a protection net in a given area by its special signal, it is the way to block the relation between cell phones and base stations. Cell phones in the area are stop working provisionally.

12W Desktop 8 Antenna 3G Cellphone GPS Bluetooth VHF UHF Signal Jammer

The powerful signal jammer/signal blocker is good at 2G 3G 4G mobile phones, WIFI, GPS, invisible earphone and bone conduction radio system. It jams the signal of targets only; do not have any harm for targets and any other electronic products. In a words, it bans the given signal frequency bands that were set in previously: CDMA 869-894MHzGSM ,GSM 925-960MHz, DCS 1805-1880MHz 1900-1990MHz ,3G 2010-2025 2110-2145 MHz ,4G 2300-2380 2555-2655 MHz and so on. Turned off the power, signal jammer/signal blocker will stop working, all target cell phones in the area can back to work at once.


Sometimes we can see signal showed on the cell phones after the Jammer working, that is a false appearance, actually .Press any bottom; you can see there is no signal appears on cell phones. Jammer’s signal is settled to against cell phones in previous, and we know, electronics products have different working frequency band, Jammer can’t jam those signal. The weak Jammer electromagnetic signal will not cause harm to human body and cell phones.


As a general signal jammer/signal blocker, it also bans GPS in car from satellite tracking. It is boring and dangerous if GPS tracker were mounted in our car secretly by evildoers, we shall against with that, otherwise, we can’t ensure our safety. Put the signal jammer/signal blocker into your car and make it work, it will show a false appearance to GPS trackers. For example, you drive away from carport but GPS tracker can’t receive the signal from satellite, so the tracker record keeps same with previous. Eight antennas jam crosswise in all their working areas to cover the shortage for each other .So the banning efficiency are much higher than the products which have built-in aerial or 4 antennas.
