EW Jammer Dobrota 3 Dual-Band 720 - 980 MHz

EW Jammer Dobrota 3 Dual-Band 720 - 980 MHz — a portable counter-UAV system for copter-type drones, developed by REBY DOBROTY LLC. The device is designed for effective protection against unauthorized flights of FPV drones and provides reliable jamming of control and video transmission channels at frequencies of 720-980 MHz. The system operates as a jammer for the 720-840 MHz and 850-980 MHz frequency bands and is equipped with an omnidirectional (collinear) high-gain antenna for stable coverage of the threat zone.

Structurally, "DOBROTA 3" includes the EW device itself with two installed non-removable antennas, a wired control panel, a rechargeable battery, a battery charger, and a 12V to 28V inverter. Thanks to its portable design, the device is convenient for rapid deployment and use in field conditions, making it a practical solution for perimeter security, security units, and military users.

Key Advantages

• Dual-band operation: covers 720-840 MHz and 850-980 MHz, allowing jamming of typical FPV video transmission and control channels;
• Powerful output: 50 W total jamming power for effective signal suppression within a radius of up to 100 meters;
• Omnidirectional (collinear) high-gain antenna for more uniform coverage of the threat zone;
• Portability and completeness: internal battery, wired control panel, charger, and 12V→28V inverter ensure autonomy and versatility of use;
