FAQ

What is the EW system “Hrets” 3M and what is it used for?

The “Hrets” 3M is a compact electronic warfare system designed to suppress FPV drone control channels in the 700–1050 MHz range. The device operates across 3 frequency bands and is used to block UAV control signals. Thanks to its weight of 6 kg and compact dimensions, the system is suitable for mobile and stationary deployment.

How does the “Hrets” 3M block FPV drone and quadcopter signals?

The “Hrets” 3M generates radio interference across three independent frequency bands used for FPV drone control. The system suppresses UAV control signals and makes it more difficult to transmit commands between the operator and the drone. Performance depends on terrain, signal frequency, and distance to the control source.

What is the power output and signal suppression range of the “Hrets” 3M?

The system’s total output power is up to 150 W with power consumption of up to 500 W. The effective suppression range is from 70 to 400 m depending on the FPV drone type, signal frequency, and operating conditions.

How many channels does the EW system “Hrets” 3M support?

The “Hrets” 3M supports 3 independent frequency bands: 700–820 MHz, 800–920 MHz, and 900–1050 MHz. This enables effective blocking of the most common FPV drone control channels in a compact form factor.

What types of power supply and cooling are used in the “Hrets” 3M?

The system operates from a 220 V mains supply and supports connection to a 28 V autonomous power source. The “Hrets” 3M is equipped with active cooling, which ensures stable continuous operation during prolonged load in field conditions.

How effective is the “Hrets” 3M in mobile and field conditions?

The “Hrets” 3M is designed for mobile use and rapid deployment. Thanks to its compact dimensions of 350×230×140 mm and weight of 6 kg, the system is easy to transport and install on vehicles or stationary positions. Operational effectiveness depends on terrain conditions, antenna placement, and UAV signal intensity.

Where can the EW system “Hrets” 3M be purchased?

The original EW system “Hrets” 3M by BlueBird Tech is available for order through the manufacturer’s official website. For consultation regarding configuration, specifications, and delivery terms, you can contact the company’s managers.
