EW Jammer «Chugayster‑M» UKR REB System — effective radio jamming device for UAV protection
EW Jammer Chugayster‑M from manufacturer UKR REB System is designed to create concentrated radio interference for the control channels of many types of UAVs, including the DJI Mavic series. The device operates at frequencies of 2400–2500 MHz and 5725–5850 MHz, is powered by a 12–28 V DC source, and can run on the included battery or an FPV drone battery. The stated operating range is up to 1000 meters, while in real field tests with an Alientech amplifier, radio suppression of the DJI Mavic multi-rotor control system reached 500 m.
Device Class
Class: EW Jammers > Trench EW Jammers. The device is designed for individual protection of military personnel from DJI Mavic-type drones at control frequencies of 2400–2500 MHz and 5725–5850 MHz.
Features and Design
- Supports two jamming bands: 2400–2500 MHz and 5725–5850 MHz.
- Each module has a power of 40 W; high-quality modules with GAN transistor and circulator are used.
- Antenna type: directional helical antennas; the antenna beam covers approximately 60° horizontally and 40° vertically for concentrated signal probing and suppression.
- Cooling: active.
- Casing: metal with plastic protective antenna covers; the design is optimized for field conditions and tactical use.
