The U-GJ04 Handheld UAV Drone Jammer is engineered with advanced signal disruption technology to provide comprehensive protection against unauthorized drone activities. This professional-grade device features a high-gain directional antenna system and four independently operated RF working units.
This drone jammer operates by transmitting electromagnetic signals at identical frequencies to override drone communication systems. This typically activates the drone's Return to Home function, enabling identification of the drone operator while maintaining operational security.
