The system features independent channels, active cooling, and the ability to control each frequency band separately, ensuring stable performance under various operational conditions.

Functions

Operating frequency ranges: 850–965, 1805–1990, 2110–2180, 2360–2505, 2570–2690 MHz.
Supports 5 independent suppression channels, enabling simultaneous disruption of multiple communication types.
Each frequency band has a dedicated switch for flexible configuration.
Each channel generates 30–50 W of output power, ensuring stable jamming performance.
Ensures continuous device operation even during extended use.

Principle of operation

After connecting to a power source, the system activates and enters operational mode.
The operator can enable all channels simultaneously or select individual frequency bands depending on the module configuration.
The system begins generating interference within the selected frequency ranges, affecting UAV control and data transmission channels.
Each module operates independently, ensuring stable performance even when the configuration is changed or individual units are deactivated.
In case of configuration changes or module replacement, channel calibration is performed to ensure correct system operation.
The device operates continuously, maintaining the specified parameters across the selected bands.
