EW Jammer Dobrota 5.1 Directional Anti-Drop for Mavics 2.4 and 5.8 MHz
EW Jammer Dobrota 5.1 — a portable counter-UAV system for copter-type drones, developed by REBY DOBROTY LLC. The device is designed for the operational protection of positions and objects from unauthorized UAV flights in the 2.4 GHz and 5.8 GHz bands and operates as a jammer for the 2400-2500 MHz and 5725-5850 MHz frequency bands (as stated in the description); the technical table also lists the 5700 - 5800 MHz range.
The system's design is portable: the main EW device body is equipped with two non-removable directional antennas of the "Directional (Clamshell)" type, a wired control panel, a rechargeable battery, and a charger, ensuring mobility and rapid deployment at a position. High-gain directional antennas allow concentrating jamming energy in a selected sector, reducing the risk of affecting adjacent equipment and frequencies.
The main capabilities and key characteristics of the device are listed in the technical table below. The unique design and settings allow for effective jamming of control and data transmission for Mavic-type copters in the 2.4/5.8 GHz bands, making the system suitable for covering flights and protecting critical areas.
| Antenna type | Directional (Clamshell) |
|---|---|
| Jamming power at the output of the jamming generation device, W | 50 |
| Electronic warfare frequency ranges | 49 |
| Electronic warfare frequency ranges | 2400 - 2500; 5700 - 5800 MHz |
| Electronic warfare range, m | 400 |
| Power supply voltage, V | 13 |
| Power supply voltage (12/24/220) | 12 V |
| Ability to operate from internal battery | No |
| Continuous operation time on battery, min | 30 |
| Continuous operation time on battery | 60 min |
| Product codified | No |
From the technical specifications: the output jamming power is 50 W, the maximum effective electronic warfare range is up to 400 meters under favorable conditions. The used frequency bands cover 2400-2500 MHz and ranges around 5.7-5.85 GHz (the description states 5725-5850 MHz, the table — 5700-5800 MHz). This allows flexible adaptation of the system's operation to specific tasks of suppressing copter control and data transmission.
The device is powered by a 13 V source (the specification also indicates 12 V for compatibility with 12/24/220 V networks). The table includes battery operation parameters: the ability to operate from an internal battery is — "No", however, the specification provides two values for continuous operation time on battery — 30 min and 60 min (both values are recorded in the original specification), which indicates configuration options or additional external power for longer operation.
The system is manufactured by the brand: REBy Dobroty. Product category: EW Jammers > Trench EW Jammers. EW Jammer Dobrota 5.1 is suitable for use in field conditions as a means of covering positions, protecting objects, and controlling airspace from small unmanned systems. With directional antennas, the operator can locally create interference in the desired sector, minimizing impact on adjacent ranges.
The package includes: a portable EW jammer body with two non-removable antennas, a wired control panel, a rechargeable battery, and a charger. The system ensures rapid deployment and convenient operation during tactical tasks.
EW Jammer Dobrota 5.1 — a practical solution for military and civilian units that need to quickly block control and data transmission channels in the 2.4/5.8 GHz bands to protect people, equipment, and objects.
