Does a GPS blocker in the car work?
Nowadays, there are more and more cars, and the information is more and more developed. This also brings convenience to travel, but it also brings convenience and information leakage. For example, many people worry about whether their travel will be tracked, so for the sake of safety, vulnerable groups, such as women, women who drive alone can install GPS blockers to prevent being tracked.
1. Vehicle GPS signal jammers are very important for some users. For example, a car mortgage company temporarily gains control of the car after releasing the money to the original owner. In order to prevent the vehicle from being secretly stolen by the original owner, such a company will purchase a GPS blocker, install it in the parking lot where the vehicle is stored, and install it in the car. It is installed on the top, so that the original owner cannot locate the vehicle, thus protecting the property safety.
2. In another situation, when you buy such a mortgage vehicle from a mortgage vehicle company, you will inevitably worry about the safety after purchasing the vehicle. Will someone install a locator on the vehicle? Will the car be driven away in the middle of the night after the car is parked? Therefore, car buyers will also buy GPS signal jammers in order to protect property safety.
3. Of course, there are other situations. For example, for some reason, you do not want the vehicle you drive to be located by others and master the driving route. At this time, you can also use a GPS signal jammer to maintain privacy.
4. The working principle of the GPS signal jammer is to cut off the GPS frequency band signal, so that the car is in a signal isolation state. The GPS jammer with 2 antennas has the following characteristics: 1. Effectively shield the GPS in the car, protect your whereabouts privacy and information confidentiality . 2. Small size, high power, light weight, large coverage, easy to carry; 3. Only shield GPS and Beidou signals, and do not affect mobile phone calls.
Of course, the GPS jammers with 6 antennas, 8 antennas and 9 antennas are more powerful. In addition to shielding GPS and Beidou signals, they can also shield 2G, 3G, 4G and wifi signals to completely block wireless signals and better protect driving privacy.
