The “Hrets” 4MC anti-drop EW system by BlueBird Tech is a vehicle-mounted modular electronic warfare complex designed to counter UAVs such as Mavic-type drones and other unmanned systems operating in the 2.4 GHz and 5.8 GHz bands. The system is installed on a vehicle and consists of four 50 W modules with Helix antennas under a protective dome. It generates interference across dual frequency bands.
Functions
- Blocking of control and data transmission channels. Operates in the 2.4 GHz and 5.8 GHz bands in dual ranges: 2360–2500 MHz / 5725–5850 MHz.
- Directional effect. Equipped with 4 Helix-type antennas under a protective dome.
- Mobile installation. Fitted with 4 neodymium magnets for quick mounting on a vehicle body.
Operating principle
- After being connected to a power source (220 V or 20–36 V), the device is activated via the control button and enters operating mode.
- The system begins generating interference in the 2.4 GHz and 5.8 GHz bands within defined frequency ranges.
- Using Helix-type antennas, the signal is directionally focused on UAV control and data transmission channels.
- As a result, communication between the drone and its operator is disrupted, making stable control impossible.
- The subsequent behavior of the UAV depends on its configuration — it may hover, lose control, or return to its takeoff point.
- The device operates continuously, maintaining a stable level of interference within the working frequency bands.
