Vehicle EW Jammer "Grets 3M" by BlueBird — Vehicle Protection Against FPV Drones
The Grets 3M vehicle EW jammer from BlueBird is a specialized electronic warfare device optimized for mounting on vehicles. The device is designed to detect and jam FPV drone control channels in the 700-1050 MHz range, making it an effective means of protecting military units, critical infrastructure, and personnel.
The "Grets 3M" design includes three independent jamming bands: 700-820 MHz, 800-920 MHz, and 900-1050 MHz, which can operate simultaneously, covering the most common FPV transmitters and disrupting the drone's control channel. Thanks to this architecture, the device prevents enemy pilot control and reduces the risk of unauthorized flight over the protected area.
The effective jamming range depends on operating conditions, pilot location, and FPV drone frequency, and is approximately 70 m to 400 m. Power is supplied from a 220 V or 28 V network, allowing the EW jammer to be connected to both the vehicle's onboard network and a stationary power supply.
Advantages of the model:
- Device weight — only 6 kg, simplifying transport and installation.
- Compact housing dimensions: 304x184x77 mm.
- Wide operating temperature range: from -30°C to +50°C, for reliable operation in various climatic conditions.
- The housing is made of materials with effective heat dissipation and is equipped with a cooling system to prevent overheating.
- Housing protection rating — IP54, providing protection against dust and water splashes.
Device prices:
Operation from 220 V with quadrifilar antennas — 122000 UAH.
Operation from 220 V with collinear antennas — 117000 UAH.
