The UAV jammer adopts the design of three antennas, which can conduct directional interference to all operating frequencies of consumer-grade UAVs. Three different frequencies can be controlled by frequency selection buttons to achieve individual or simultaneous interference. The shape is smooth and the edges and corners are sharp, just like the sharpness of firearms. The shell is added with color masterbatch injection molding, without spraying, the material has recyclability and recyclability, reducing pollution to the environment. Through the shape design, the antenna and other components are hidden in the housing, and the overall feeling and product feel are better. The product shows a professional sense of equipment and deterrence. The handle, sight, and center of gravity also get the most suitable position through user experience, solving fatigue during frequent operations. With the popularity of consumer-grade drones, large venues and sensitive key departments are increasingly threatened by drone invasion. The UAV jammer can effectively force the UAV to return to and land, and protect the safety of the relevant airspace.
