HD-4 – Vehicle-mounted drone Jamming system with remote antennas

HD-4 is a high-performance vehicle-mounted anti drone jamming system designed to counter UAVs, FPV drones, and other unmanned aerial threats in mobile environments. With four independent jamming channels, each delivering up to 50W of output power, the system provides a total output of 200W, ensuring strong and stable interference performance.

This counter-drone jammer is supplied with externally mounted antennas featuring magnetic bases, along with four 3-meter extension cables. The external antenna design allows flexible placement on vehicle bodies, making HD-4 an ideal mobile and transport-based electronic countermeasure solution.

When active, HD-4 generates an omnidirectional jamming field that forms a protective interference zone around the vehicle. Under standard operating conditions, the effective jamming radius typically ranges from 100 to 300 meters, while in favorable environments the range may extend significantly further.

In close-range scenarios where the drone operator is located near the UAV, video transmission can be completely disrupted at distances of approximately 200 meters. When the operator is positioned several kilometers away, the video link is usually neutralized within 300–500 meters, with occasional extended coverage depending on terrain and signal conditions.

HD-4 operates across four widely used frequency bands:

2400-2500 MHz(2.4G WiFi), 5727–5850 MHz(5.8G WiFi), 1570–1620 MHz(GPSL1), and 868-915 MHz(remote control).
These bands cover the most common FPV control frequencies as well as the primary video transmission channels used by the majority of commercial and tactical drones. {Applicable to 90% of commercial drones}

The system features a robust, heat-dissipating enclosure combined with an efficient active cooling system. Multiple high-power cooling fans ensure reliable thermal management of the jamming modules, allowing continuous operation without overheating or automatic shutdown.

For maximum deployment flexibility, HD-4 can be powered either from a standard 220V AC source or via a vehicle power inverter, which is included in the package. This makes the system suitable for both stationary installations and mobile vehicle-based use.

The housing includes a practical mounting bracket that can be securely fixed to various surfaces or installed directly inside a vehicle, enabling fast setup and stable operation in different environments.
