You can freely choose the frequency you want to interfere with, unlike other portable jammers, where one antenna can only perform fixed single interference. Although our Cellular Blockers for Home Use has only 4 antennas, it does not mean that it can only interfere with four frequency bands. Our product is configured to continuously and simultaneously interfere with 8 different frequency bands.
What are the eight frequencies mentioned above? You can refer to the following interference frequency range table:
| Antennas 1-2 | CDMA: 850 – 894MHz |
| GSM: 925 – 960 MHz | |
| Antennas 3-4 | PCS: 1920 – 1990MHZ |
| 3G: 2110 – 2170 MHz | |
| Antennas 5-6 | 4G LTE: 2300 – 2400MHz |
| Wi-Fi 2.4G: 2400 – 2500MHz | |
| Antennas 7-8 | GPS L1: 1550 – 1580MMHz |
| Glonass L1: 1570 – 1620Mhz |
On the front view of the 4G Android cellphone jammer, you can see that it has eight separate switches, and when operating, there is a mini indicator lamp above each switch that will flash, so that you can understand which frequency band the target of interference is or check whether it is working properly.
There are many other possibilities for this mobile phone jammer. After you purchase this product, we will give you a free car charger, which is adapted to the DC 12V power interface. In this way, you can use the 4G Android Cellphone Jammer in your car.
I believe that anyone who is tracked will be unhappy, so our product has anti-GPS positioning technology, but it can only block GPS L1 & Glonass L1 signals.
For unreasonable Bluetooth speaker players, you can turn on the corresponding DIP switch(Band Switch) to stop their behavior. This jamming device can block signals within a range of 20 meters. I believe this is enough for you.
