GSJ UAV Drone Signal Jammer Blocker 5 Channel Anti Drone Gun for DJI Drone

DescBoost 5 Channel UAV Drone 

This UAV drone gun can create a "no-fly zone" for drones, effectively preventing drones from transporting hazardous goods and performing malicious surveillance. In the 1500-2000 meter range, this Handheld  Anti Drone Gun Jammer  can jam frequency bands of GPS, 2.4G, and 5.8G, 800-900M, forcing the drone to leave or land immediately.

 Usage

Use the antenna to correspond to the center of the shielding area, as shown in the figure below:

Working Mode

• Force to Land: When all switches are turned on, the drone is forced to land.
• Return: When the GPS is turned off and 2.4G/5.8G/900M is turned on, the drone is out of control, and the drone returns at this time.
• Lose Position: When the 2.4G/5.8G/900M is turned off and the GPS is turned on, the drone loses its positioning, and the drone can be controlled remotely at this time.

Specifically for visible drone interference, the effective distance is about 100 meters away from the drone and the interference is more than 1500 meters.

Wireless communication must ensure a sufficient carrier-to-interference ratio (signal-to-noise ratio) in order to effectively receive and complete communication. The communication signal jammer is to destroy the reception conditions of the UAV by generating an interference signal of the same frequency as the UAV receiving and cutting off the communication connection between the UAV and the remote control transmission, so as to achieve the effect of interfering with the communication.

The interference power is fixed, and the shielding radius of the unobstructed space is determined by the path attenuation and the control of the remote control transmission signal level. The table below provides a comparison table of distance and path attenuation. Then the coverage radius can be determined by the output channel power of the jammer, the remote control signal level, and the gain of the coverage line. The formula is as follows:

Pch+Gat-L-FAF≥Prx

In the formula:

      Pch: Minimum channel power output from the jammer

      Gat: Antenna gain

      L: Path attenuation

      FAF: Path loss additional value, take 6-8dB

      Prix: Received signal strength
