Designed specifically for operators working in demanding environments, the DF-A0389 provides quad-band direction-finding capability covering an exceptionally wide frequency range from 20 MHz to 18 GHz. The system spans four discrete bands: Band B (20–500 MHz), Band C (400 MHz–2 GHz), Band D (2–8 GHz), and Band E (6–18 GHz), enabling users to detect and locate a broad range of communication and radar signals with a single integrated solution.
At the heart of the system is a four-channel correlative direction-finding architecture capable of delivering excellent RMS accuracy. This high level of precision allows operators to rapidly identify and locate signal sources, providing valuable intelligence and enhancing operational decision-making. Per-channel low-noise amplification helps maintain signal integrity across the entire frequency spectrum, while passive bypass capability ensures continued operation even in challenging RF environments.
A key advantage of the DF-A0389 is its focus on reducing operator workload. Integrated GPS with an active L1 antenna, onboard navigation functionality and built-in RF chain calibration minimise setup requirements and simplify deployment. The result is a system that arrives mission-ready, enabling operators to spend less time configuring equipment and more time focusing on operational objectives.
Built to withstand harsh field conditions, the DF-A0389 is rated to IP66 standards, designed in accordance with MIL-STD-810F requirements for ground vehicle applications, and operates reliably in extreme temperatures ranging from -30°C to +70°C. Its rugged construction and manpack-ready form factor make it ideally suited for tactical and mobile operations on multiple platforms where size, weight and reliability are critical considerations.
With the introduction of the DF-A0389, Alaris Antennas continues to deliver advanced RF solutions that combine wideband performance, operational simplicity and rugged reliability. The system provides defence and security forces with a powerful new tool for direction finding at the tactical edge, helping operators locate, track and respond to signals with greater confidence and precision.
