Product introduction:

The car GPS series signal shielding device is the third generation green GPS signal shielding device, which only shields the receiving signal of the on-site GPS terminal, and has no negative influence and interference on communication and transmission of other electronic devices around. This machine adopts dual output and can cover all kinds of GPS signals such as all positioning terminals within the range of 15-50 meters (depending on the strength of satellite signals), so that all GPS positioning terminals within the shielding range are completely connected with the outside world. Interrupted. The rated working voltage of this product is 12-24V. Both the cart and the trolley can be used directly, the working frequency bandwidth is 20MHz, the frequency range is: 1560-1580MHz; 1150-1250MHZ.

Instructions for use:

1. Take out the GPS device and install the antenna.

2. Insert the corresponding cigarette lighter port of the car.

3. When the device is powered on, the indicator lights up and works normally.

4. Remove the GPS signal blocker directly when you are finished using it.

    Monitor the platform speed, stay still before moving or no


Pay attention to the following points when using the car GPS shield:

1. Is the shielded antenna intact?

2. Is the interface between the antenna and the instrument tight?

3. Whether the inserted instrument is in good contact with the cigarette lighter of the vehicle.


1 The shield is maintenance-free and requires no maintenance.

2 When wiping the surface, use chemical solvents and avoid water in the machine.

3 When the shielding device is useful, it should be stored in a dry and ventilated place to avoid prolonged contact with salt spray and harmful gases.
