350W Vehicle-Mounted UAV Jammer for DJI, FPV and GPS/WiFi Drone Signal Blocking

Not every drone jamming device is built for the same job. Compact handheld units (flashlight) focus on size and convenience, while vehicle-mounted systems focus on output power, antenna placement, and long-duration operation.

This FPV system signal blocker belongs to the second category, employing a 350W high-power output platform. Combined with high-gain magnetic antennas, the system achieves an operating range of 500-800 meters, making it suitable for applications where a stronger and more stable signal output is required.

The UAV frequency Jammer supports multiple frequency bands commonly used by consumer-grade and FPV drones:

These frequencies are widely found in popular quadcopter platforms such as:

• DJI Mavic series
• DJI Air series
• DJI Mini series
• DJI Avata FPV drone
• Autel EVO series
• Other FPV drones using common wireless control and video transmission frequencies

The actual response can vary depending on quadcopter model, environment, signal strength, and operating conditions.

The biggest feature of the UAV signal scrambler is its 350W output power. This level of power requires more than a standard battery setup, the system is equipped with a 24V vehicle power connection cable with alligator clips.

The vehicle-based power connection allows the signal blocking equipment to work with a continuous energy source instead of being limited by short battery runtime..

High power system cannot rely on a basic ventilation design, our anti drone signal blocker uses the entire chassis as part of the cooling process.

The aluminum alloy fin structures on both the upper and lower sides increase the contact area for heat release, while the dual fans at the bottom continuously push air through the internal components. Instead of cooling only one area, the airflow is distributed across the unit to support long-duration operation.
