Car positioning shields are very important to some customers. For example, a vehicle mortgage company temporarily obtains the decision-making power of the car after depositing the money to the original car buyer, so as to avoid the car being quietly taken away by the original car buyer. This type of company will purchase positioning shields and park the car in the underground. Installed on the field and on the car, so that the original buyer cannot locate the car, thereby protecting the safety of funds.
If you buy this type of vehicle from a mortgage company, you will inevitably worry about the safety hazards after buying the car. Will someone install a locator on the car? Will the vehicle be parked in the middle of the night and taken away by others? Therefore, in order to ensure the safety of funds, car buyers will also purchase positioning GPS jammer in specialty stores.
Naturally, there are other situations. For example, for various reasons, you don't want your car to be accurately located by others and grasp the safe driving route. At this time, you can also use the positioning shield to maintain privacy.
Its principle is to disconnect the frequency band data signal for positioning, so that the car is in a data signal isolation state. The two antennas have the following characteristics:
1. Reasonably affect positioning and Beidou navigation satellite data signals, and maintain your track privacy protection and information content business secrets.
2. Small size, large output power, light weight, large coverage area, and easy to carry.
3. Only the positioning and Beidou positioning system data signals are shielded, and the answering of the mobile phone is not affected.
Of course, six antennas, eight wireless antennas, and eight antennas are more powerful. In addition to shielding the positioning and Beidou positioning system data signals, it can also shield 2G3G4G and wifi signals, blocking network signals in all directions, and ensuring driving privacy. protection.
