Trench-Vehicle EW Jammer "Hrets 4MTSO" from BlueBird is a modern mobile electronic warfare (EW) jammer designed for effective protection against quadcopters, including DJI Mavic, and other unmanned aerial vehicles operating in the 2.4 GHz (2x) and 5.8 GHz (2x) bands. The device generates four separate jamming bands (2360-2500 MHz and 5725-5850 MHz), allowing simultaneous jamming in all critical bands and increasing the probability of neutralizing threats due to the dual bands.
The "Hrets 4MTSO" EW jammer is designed to protect military units, infrastructure facilities, and civilian areas from reconnaissance and drone attacks with potential drops. Thanks to two dual bands and a powerful area of effect, the device provides a larger jamming radius, especially when the bands overlap at different angles to create cross-interference.

Kit Description and Delivery Contents:
The delivery kit includes all essential elements for readiness for operation and mounting on a vehicle or stationary mast:
- 1. EW Jammer Device.
- 2. Four Antennas.
- 3. 220 V Power Cable.
- 4. Bracket for mounting 4 antennas on a vehicle or mast.

The device's design allows for field operation: the housing is made of heat-dissipating materials to prevent overheating and ensure stable performance. The original description includes both housing dimensions — 350x230x140 mm and 304x184x77 mm — both values are preserved in the technical data. The weight without battery is 6 kg. The text also notes a discrepancy in the number of antennas in the kit: some parts of the description mention 5 antennas, while the technical table specifies 4 "Clover" type sector antennas — this information is preserved to accurately reflect the original data.
The device can be powered from a 220 V mains or a 28 V on-board system, allowing installation in both stationary locations and on vehicles. The operating temperature range is from -30°C to +50°C, and the IP54 protection rating guarantees reliable protection against dust and water splashes, allowing the device to be operated in challenging climatic conditions.
Scope of application: protection of military units, critical infrastructure, ensuring the safety of civilian objects, and operational jamming of drone communications in the area of responsibility. The presence of sector antennas, brackets, and patch extension cables provides flexibility in placement and configuration to achieve optimal coverage. The total power of the sections (50+50+50+50) W and corresponding power consumption (150+150+150+150) W allow for adjusting the operating mode depending on the tasks.
