We all know that once we buy a jammer, the first thing we receive is to test whether the signal jammer can work normally, and before the test, the first thing you need to do about the signal jammer is to install the antenna. In order to ensure the normal operation of the signal jammer, just like you did not connect the signal jammer antenna correctly, the entire jammer may be burned, so that we can see that it is very important to install the antenna correctly, otherwise the signal jammer will not work properly operation.
But now many people have encountered this problem: sometimes they will put the antenna on the floor and then break it, they are really looking for a solution to the problem, so what can they do to solve this problem? Yes, now they can really take a solution to the current problem, here you can look at this "powerful portable jammer antenna", and then you will understand this signal jammer antenna about those who are in need of it, see See how it will assist you and its more important aspects.
The jammer is good at shielding the 2G 3G 4G signal of the mobile phone, WIFI, GPS, invisible earphone and bone conduction radio system. It only obstructs the signal of the policy; it does no harm to other policies and any other electronic products. In short, it prohibits the previously set given signal frequency bands: CDMA 869-894MHzGSM, GSM 925-960MHz, DCS 1805-1880MHz 1900-1990MHz, 3G 2010-2025 2110-2145 MHz, 4G 2300-2380 2555-2655 MHz, etc. . After turning off the power, the signal jammer will stop working, and all target mobile phones in the area can resume operation immediately. It also prohibits on-board GPS for satellite tracking. If GPS trackers are secretly installed in our cars by bad guys, it will be boring and risky. We firmly oppose this approach, otherwise, we cannot ensure our safety. Put the GPS jammer into your car and make it work, it will show the wrong appearance to the GPS tracker. For example, you drive away from the garage, but the GPS tracker cannot receive the signal from the satellite, so the tracker record remains the same as before. Eight antennas are cross-shielded in all operating areas to compensate for each other's lack.
