The H1B-D is a tactical handheld drone detection terminal specifically engineered for high-precision Direction Finding (DF) in the field. Unlike standard omni-directional detectors, the H1B-D comes equipped with a specialized external DF Antenna, allowing security personnel to manually scan the horizon and pinpoint the exact azimuth of an intruding UAV and its operator. This device is an essential asset for rapid response teams who need to not only detect but also visually locate threats in seconds.

Precision Direction Finding & Locked DF Mode
The standout feature of the H1B-D is its Locked DF Mode. Utilizing the high-gain directional antenna, the operator can achieve a probe azimuth accuracy of ≤30°. This narrow field of detection allows for the effective isolation of a target signal within a 1-2 km radius, even in environments with multiple active RF sources. This "point-and-detect" methodology is critical for identifying the specific approach vector of a drone.

Dual-Frequency Architecture
The system operates across two distinct operational modes to maximize search efficiency:

Omni Detection: Scans the 900MHz, 1.1GHz, 1.2GHz, 1.4GHz, 2.4GHz, and 5.8GHz bands for general airspace monitoring and early warning.
Directional Detection: Concentrates energy on the 2.4GHz and 5.8GHz bands for precise localization of mainstream commercial and tactical drones.
Field Reliability & Performance
High-Capacity Battery: Powered by a massive 10000mAh (37Wh) internal battery, the H1B-D provides over 6 hours of continuous monitoring—more than enough for a standard field mission.
Intelligent Identification: Capable of analyzing protocol signatures to identify more than 10 drones simultaneously, including models from DJI, Autel, FEMI, Yuneec, and wide-band FPV racers.
Low Power Dissipation: Efficient industrial design keeps power consumption below 6W, ensuring lower heat signatures and longer component life.
