The composition and principle of the UAV jammer. The equipment consists of a handheld host and a battery pack. The handheld host is a three-band transmitter antenna integrated design, which can simultaneously generate 2.4GHz/5.8GHz frequency UAV flight control interference signals and satellite positioning interference signals, through the UAV's uplink flight control channel and satellite positioning channel. Blocking interference causes it to lose flight control instructions and satellite positioning information, making it unable to fly normally. Depending on the design of the UAV, it will have the control effect of returning, landing and falling.

In the offensive and defensive situation, there is usually a certain distance between the drone operator and the sensitive area that needs to be fortified. The drone took off from the vicinity of the manipulator, and then gradually flew towards the fortified area. When the drone arrives near the fortified area and can carry out effective reconnaissance or sabotage activities, the distance from the drone to the fortified area is usually much closer than its distance to the manipulator.
