4 Channels Anti Drone Gun
Definition: A drone jammer gun is a portable device that disrupts drones' communication and navigation signals. Emitting powerful electromagnetic waves interferes with the signals that drones rely on to operate.
Form factor: Use directional antennas and a rifle.
Jamming distance: 1000-2000 meter range
Frequency bands: GPS, 2.4G, and 5.8G, 800-900M
Function: can create a "no-fly zone" for drones, effectively preventing drones from transporting hazardous goods and performing malicious surveillance.

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

Cautious
- The antenna must be connected first, and then turn on the power. Do not remove the antenna when the host is working.
- The drone counter-gun should be placed in a well-ventilated place, and try to avoid the blockage of large objects to ensure the shielding effect.
- When using the shielding device outdoors, pay attention to waterproofing and avoid exposure to sunlight.
- The antenna should be used vertically facing the drone.
