EW Jammer «DOBROTA 1» — Portable UAV Countermeasure System (410-520 MHz)

EW Jammer Dobrota 1 by FPV Ponizhenyi 410 - 520 MHz — a portable countermeasure system for copter-type unmanned aerial vehicles, developed by DOBROTY EW LLC (brand: REBy Dobroty). The device is designed to protect against unauthorized FPV drone flights by creating radio interference in the 410-520 MHz operating range. The system functions as an interference generator with an omnidirectional (collinear) high-gain antenna, ensuring stable jamming of control and video transmission channels.

Structurally, the complex consists of a main EW unit with a non-separable collinear antenna, a wired control panel, a battery pack (АКБ), a charger, and an inverter for voltage conversion from 12V to 28V. The device is compact and convenient for operational use in the field, ready for quick deployment and operation in the area of responsibility.

Key Features

• Manufacturer: DOBROTY EW LLC (brand: REBy Dobroty).
• Purpose: protection against FPV drones and copters, operational suppression of control and video transmission channels.
• Operating suppression range: 410-520 MHz (declared range).
• Antenna: collinear, non-separable, omnidirectional with high gain.
• Integrated kit: EW device, one non-separable antenna, control panel, battery pack, charger, 12V→28V inverter.

Technical Specifications

Thanks to its 50 W output power and a maximum declared range of up to 400 m, the «DOBROTA 1» solution creates an effective radio suppression zone to prevent unauthorized takeoffs or intelligence gathering by FPV copters within the specified frequencies. The presence of an integrated 12V→28V inverter and power supply kit makes the device convenient for field operations; however, it should be noted that the ability to operate from an internal battery is indicated as «No», and the continuous operation times on the battery are specified in the table (30 min and 60 min), so for prolonged operations, an external power source or spare batteries are recommended.

The device is not codified, which should be considered when planning its operation and ensuring compatibility with other means within the complex. Its compactness, ease of control from the wired panel, and the presence of all necessary components in the kit make «EW Jammer Dobrota 1» a reliable choice for operational counteraction against FPV drones on the battlefield or in border/security operations.
