EW system Hrets 5UL

The “Hrets” 5UL EW system by BlueBird Tech is an electronic warfare system designed to protect positions from FPV drones by creating a stable radio suppression field. The system operates in the 170–600 MHz range and forms a signal suppression zone around the deployment point, effectively blocking UAV control channels.

Functions

• The system operates in the 170–600 MHz frequency range, which is typical for radio-controlled UAVs.
• Each channel corresponds to a specific frequency band, allowing effective coverage of the threat spectrum.
• The system can generate interference across all bands simultaneously, creating a continuous suppression field.
• Each band is activated by a separate button, enabling flexible control of load and operating mode.
• Each channel has an indicator light showing its activity status.
• The system is optimized for deployment in field positions and ensures stable operation under field conditions.

Operating principle

1. After being connected to a power source, the system activates and enters operating mode.
2. The operator can switch on all channels simultaneously or select individual frequency bands according to the module configuration.
3. The system begins generating interference in the selected frequency ranges, affecting UAV control and data transmission channels.
4. Each module operates independently, ensuring stable system performance even when the configuration changes or individual units are disconnected.
5. In case of configuration changes or module replacement, channel calibration is performed to ensure correct operation of the system.
6. The device operates continuously, maintaining the specified parameters within the selected frequency bands.
