Trench EW Jammer Grets 6M — is a modern high-tech electronic warfare device designed for reliable protection of military facilities, infrastructure, and personnel from unmanned aerial vehicles (UAVs) in the operating range of 700-1050 MHz. The device jams drone control signals and FPV transmitters, providing comprehensive protection for perimeters, command posts, and other critical areas.

Grets 6M is equipped with three independent jamming bands: 700-820 MHz, 800-920 MHz, and 900-1050 MHz, which can operate simultaneously. This multi-band architecture allows for effective neutralization of the most common types of FPV control sources and FPV bomber drones at a distance of 70 m to 400 m depending on specific conditions (distance to the operator, UAV operating frequency, environmental interference, etc.).

Manufacturer: BlueBird. Category: EW Jammers > Trench EW Jammers. The Trench EW Jammer Grets 6M combines a robust housing measuring 475x325x126 mm, mobility, and the ability to be mounted on a vehicle or stationary stand using the included bracket. Six antennas, assembled in three pairs at a 45° angle, provide directional and uniform coverage of jamming zones in three bands simultaneously, allowing for effective protection of perimeters, logistics hubs, fortifications, and other critical objects.

The modular design, a set of 2 m cables for each band, and the bracket allow for quick deployment of the system in field conditions. The availability of optional components — 28 V power supply, springs for mounting antennas on a vehicle, additional "Quadrifilar" antennas, and a remote control — ensures high operational flexibility and allows the EW jammer to be adapted to specific customer tasks. The total power and power consumption parameters provide a clear understanding of the resources required for stable operation in combat and training conditions.

This complex is designed for use where reliable UAV countermeasures are needed: protection of command posts, military units, logistics centers, critical infrastructure, and temporary positions. Thanks to the combination of power, mobility, and rapid deployment, Grets 6M effectively solves the task of local suppression of unmanned threats.
