Directional-radio Suppression Device

Our directional radio suppression equipment is capable of transmitting high-power jamming signals in a directional manner, forming an electronic fence, blocking communication between the drone and the operator, and causing it to lose satellite positioning and control. It can be set up to force the drone to return, land or hover, and is widely used in the military, airports and other fields and commercial activities.

This directional signal suppression technology projects high-intensity interference waves to establish a cylindrical defense perimeter, disrupting critical UAV operator communications and satellite positioning data. Through targeted electromagnetic intervention, it creates an electronic barrier that severs drone control links and navigation capabilities. Based on target UAV configurations, the system enforces flight termination protocols including forced return-to-origin, emergency grounding, or stabilized aerial suspension. Equipped with a 360° motorized gimbal, the device ensures omnidirectional protection for diverse security applications across military, judicial, aviation, diplomatic, energy, and critical infrastructure sectors, as well as large-scale public events like athletic competitions, concerts, and expositions.
