Will GPS signal jammers shield cell phone signals? In fact, not all gps jammers can shield cell phone signals. Let me introduce to you.

Initially, the car GPS jammer was a wire installed in the car's cigarette lighter position, After ignition, the power supply can shield the GPS signal. Later, it evolved into a 1-antenna GPS Jammer. In addition to powering the car, it also has a lithium-ion battery. It can also use its own accumulator to operate normally for a period of time. Later, two antenna shielding devices appeared, and the two antennas respectively shielded the gps frequency band and the Beidou satellite positioning frequency band.

They are all pure gps signal jammers and do not shield cell phone signals. But on this basis, portable GPS jammers with 3, 4, 6, and 8 antennas have emerged, which can shield GPS, mobile phones and WiFi signals, and have more powerful functions. However, in the current market, 3 or 4 antennas are relatively rare. Excluding the pure gps shielding device with 2 antennas, the facilities with 6 or 8 antennas have become mainstream products.

The GPS signal jammers above are all portable and lighter, with a built-in lithium-ion battery, which can work for several hours even in the event of a power failure. It is even possible to carry the signal shielding device with 6 or 8 antennas on the body to block the interference of external data signals when negotiating in some hidden places.

In addition to this type of portable GPS jammers, there is also a type of desktop GPS signal jammers that are larger but more powerful, with 8 or 9 antennas, and full coverage of GPS signals and mobile phone signals. It does not have a lithium-ion battery, and can only be operated with electricity. It can work with 220V alternating current in the parking area, and it can also work with 12V power in the car. This type of facility also comes with adjustable buttons, which can only block gps signals or mobile phone signals according to application requirements.

After reading the above, do you have a clearer understanding of gps signal jammer?
