B&G HALO 20 24nm Radar Antenna

The HALO20 radar is an affordable solution for boaters to increase situational awareness and collision avoidance by detecting collision hazards and other targets nearby and up to 24 nautical miles away. With its small footprint and low profile, the HALO20 is the perfect radar solution for budget-conscious buyers with sportfishing boats and smaller recreational boats. The HALO20 radar also offers a full range of features to enhance situational awareness and safety on the water. Boaters can monitor selected collision hazards with MARPA target tracking, tracking up to 10 targets. Whether navigating crowded waterways or contending with poor visibility, HALO20 radar cuts through the clutter to give boaters a clear, up-to-date picture of their surroundings.

Excellent performance in short and medium distances
Extend your view from the bow of your vessel up to 24 nautical miles with pulse compression radar technology that not only provides a powerful mix of close- and long-range detection, but also delivers precise target definition with minimal clutter.

Short and long range vision with a single compact antenna
Ideal for a wide range of small powerboats, the HALO20 comes with a compact dome antenna that delivers high-quality short to medium range detection.
HALO20 radar's pulse compression technology compromises no detection range at any selected range, while beam sharpening provides improved separation between small or distant targets.




Always ready for use
HALO20 radar wakes instantly from low-power standby mode, providing high-speed radar coverage exactly when and where you need it. Even when HALO20 radar is completely powered off, it starts up in seconds, unlike traditional pulse radars that take minutes. Whether navigating through crowded waterways or in poor visibility, HALO20 radar instantly filters out clutter to provide a clear, up-to-date picture of your surroundings.
