Trench EW Jammer "Grets" 5ML from BlueBird is a mobile electronic warfare countermeasure designed for effective jamming of FPV UAVs operating in the 350–700 MHz range. The device is intended for field deployment, installation on vehicles or stationary tripods, and provides reliable protective action at distances up to 400 m, depending on conditions and the frequency of the enemy drone. The "Grets – 5ML" EW jammer combines five separate jamming bands with the ability to simultaneously create interference across all ranges, increasing the likelihood of disrupting communication between the pilot and the enemy's aircraft.
Features and Capabilities
The device has five separate jamming bands: it covers the range from 350 to 700 MHz and allows for selective or simultaneous operation across all bands. This design makes "Grets – 5ML" a versatile solution for suppressing FPV drone communication links of various standards. The device is equipped with high-quality collinear and quadrifilar antennas that have undergone field testing and received positive feedback for their effectiveness and reliability.
Frequency Bands
- 350-410 MHz (collinear);
- 400-460 MHz (quadrifilar);
- 450-530 MHz (quadrifilar);
- 500-580 MHz (collinear);
- 575-700 MHz (collinear).
