Anti-drop EW Hrets 4MC

Q: What is the EW anti-drop “Hrets” 4MC, and what is it used for?

The EW anti-drop “Hrets” 4MC is an electronic warfare system designed to counter DJI Mavic-type drones. The system generates directional interference in the 2.4 GHz and 5.8 GHz frequency bands.

Q: What is the drone neutralization range of the “Hrets” 4MC?

The system is effective at a distance starting from 130 m at a target altitude of 50 m and from 180 m at an altitude of 100 m. The maximum neutralization altitude is up to 250 m. The actual range depends on terrain conditions, the transmitter power of the drone operator, and the presence of obstacles in the operating area.

Q: How quickly can the “Hrets” 4MC be installed on a vehicle?

Mounting is carried out using 4 neodymium magnets directly on the vehicle body. Power connection is implemented via a 5 m extension cable with a control button. This mounting method allows the system to be quickly installed and removed depending on the mission.

Q: What power supply is required for the operation of the “Hrets” 4MC?

The system supports connection to a 220 V mains supply or an autonomous power source with a voltage of 20–36 V. The total power consumption of all four modules is up to 700 W. For autonomous use, it is recommended to use a suitable charging station or a battery with sufficient capacity.

Q: Does the “Hrets” 4MC have NATO codification?

Yes, the EW anti-drop “Hrets” 4MC by BlueBird Tech has NATO codification, which confirms the product’s compliance with international standards.

Q: What is the warranty for the EW anti-drop “Hrets” 4MC?

The warranty period is 12 months from the date of purchase. Service is provided by the BlueBird Tech service center. The warranty does not apply in case of mechanical damage, violation of operating conditions, or unauthorized modification of the device.

Q: What is included in the “Hrets” 4MC package?

The package includes: the EW anti-drop “Hrets” 4MC unit, 4 Helix antennas (2.4 GHz and 5.8 GHz) with a protective dome, and a power cable. A user manual is also included. No additional accessories are required for standard deployment.

What kind of device is this?

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.
