UAV signal suppressor Hrets 4G
“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 “Hrets” 4MO electronic warfare system by BlueBird Tech is a codified EW solution designed to counter FPV drones by suppressing control channels within operating frequency ranges. The system operates in the 450–530 MHz and 700–1050 MHz bands, features four separate jamming channels, and supports simultaneous blocking of the most commonly used FPV transmitters.
The device can be deployed on vehicles or at stationary positions, and its compact size, rugged housing, cooling system, and IP54 protection rating ensure stable performance in field conditions.
Functions
- Operates within selected frequency ranges: 450–530 MHz, 700–820 MHz, 800–920 MHz, 900–1050 MHz.
- Enables blocking of multiple popular FPV transmitter frequencies and effectively counteracts various control channels.
- Supports simultaneous activation of all channels to create a dense electronic suppression field.
- Equipped with a heat-dissipating housing and a cooling system to prevent overheating during extended operation.
Principle of operation
- After connecting to a power source, the system activates and enters operational mode.
- The operator can switch on all channels simultaneously or configure the device according to specific mission requirements.
- The system begins generating interference within the selected frequency ranges, affecting FPV drone control channels.
- Depending on the type of installed antennas, the device provides effective coverage for either a moving platform or a stationary position.
- The system operates continuously, maintaining the specified parameters across the selected bands.
