The RfOne Mk2 from DroneShield (Australia) is a long-range passive RF sensor for detecting and bearing drones, for stationary or vehicle-mounted installation. One unit covers a sector; four units cover 360 degrees. The manufacturer names military use and critical infrastructure as fields of use.
The maximum range is 8.0 km according to trade press (2021). It is a value under favourable conditions: the range of a passive detector depends on the drone’s transmit power, line of sight and radio environment, and it drops markedly in a city. The sensor uses its bearing to determine the direction from which a control or video signal comes; four units therefore give all-round cover, and several sites would give a position by cross-bearing.
The sensor is passive and does not interfere with the drone’s radio link. Whether and how receiving and evaluating third-party radio signals is permitted (secrecy of telecommunications, data protection) has to be clarified for Germany and Poland before use. Detection is to be kept apart from countermeasures: jammers may be operated only by authorities in Germany and Poland (Section 91 TKG, Article 42 of the Polish Electronic Communications Law).
In selection, plan for four units to get all-round cover: four mounts, cable runs and power connections. For bearings the alignment of each sensor counts; on a vehicle, metal surfaces and other antennas interfere, and the sensors have to be aligned anew after a move. The signature library needs upkeep so that new drone types are recognised. Radio silence remains the limit: a passive sensor does not see autonomous or fibre-optic controlled drones, and radar or cameras complement it.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Ask about parts availability for this build year — the running costs hang on it.
