Hrets 4G UAV Signal Suppressor
“Hrets 4G” is a UAV communication jammer that blocks data transmission and control signals within a radius of up to 10–40 m indoors and from…
The “Anti-Drop” backpack for field conditions by BlueBird Tech is a portable electronic warfare device designed to suppress communication channels of DJI Mavic-type drones and other unmanned aerial vehicles operating in the 2.4 GHz and 5.8 GHz frequency bands. The system is intended for mobile groups, crews, personnel, and units operating in field conditions that require individual or localized protection against drones with payload-dropping capabilities.
The backpack features a mobile design and is equipped with a built-in EW module, battery, control unit, and a wattmeter with a display. This allows the operator to quickly prepare the device for use, monitor its operation in real time, and deploy the system without the need for an external power source.
Functions
- The backpack is designed to be carried by the operator during movement, mission execution, patrols, convoy escort, or evacuation operations.
- The system operates from a built-in battery and provides up to 50 minutes of autonomous operation on a full charge.
- The device features a simple control interface that allows the system to be quickly switched on or off in response to a threat.
- The operator can monitor voltage, power consumption, and the overall system status during operation.
Operating principle
- After connecting the battery and switching on the control unit, the system enters operating mode.
- The operator activates the device by pressing a button on the remote control.
- The backpack then generates directed broadband noise interference in the 2.4 GHz and 5.8 GHz frequency bands.
- The resulting radio interference disrupts the communication link between the drone operator and the UAV, which may lead to loss of control, automatic landing mode, or return-to-home behavior.
- During operation, the operator monitors real-time parameters via the wattmeter.
- The device is recommended for use only in the presence of a real threat — when a drone is approaching or suspicious activity is detected. The optimal continuous operating time is 5–10 minutes, after which a pause should be made.
