Dome EW Jammer "Grets" 5ML from BlueBird is a specialized device for suppressing FPV UAVs in the 350-700 MHz frequency range, designed for use in both stationary and mobile configurations (mounted on a vehicle or stand). The device operates in the 350-700 MHz band and has five separate jamming bands with the ability to simultaneously create interference in all bands.
Features and Functions: Operates in a wide range of 350-700 MHz; five separate jamming bands provide flexibility in configuration and high efficiency; simultaneous jamming across all bands to block FPV control and video transmission channels.
Frequency Bands of EW Jammer "Grets — 5ML":
- 350-410 MHz (quadrifilar)
- 400-460 MHz (quadrifilar)
- 450-530 MHz (quadrifilar)
- 500-580 MHz (quadrifilar)
- 575-700 MHz (quadrifilar)
Quadrifilar antennas have been tested in real conditions; they received positive feedback for their effectiveness and reliability. The device can be used in various UAV countermeasures scenarios where simultaneous coverage of several frequency ranges is required.
