The Dream-A 2001 drone omnidirectional countermeasure device utilizes the principle of blocking interference to block all possible communication channels of the drone, forcing the communication and navigation link terminals of the drone to construct a comprehensive drone no fly zone. It emits interference electromagnetic waves in a global form, efficiently shields drone signals, and forms an effective barrier against multi-target drones. Suitable for countering full frequency unmanned aerial vehicles, cellular unmanned aerial vehicles, and swarm formation unmanned aerial vehicle intrusions.
