Detailed description

The B&G HALO20 dome radar is a compact 20-inch solution incorporating pulse compression technology. Designed for sailboats and smaller vessels, it uses 10W of transmit power to provide clear and accurate detection up to a maximum range of 24 nautical miles. Its InstantOn™ technology ensures immediate availability from low-power standby mode, eliminating the warm-up time of traditional magnetron radars.

Performance and detection modes

The HALO20 offers short-range detection from 50 meters, essential for navigation in congested areas. The rotation speed is fixed at 24 RPM. The beam has a width of 4.9° horizontally and 25° vertically. Several operating modes are available to optimize the display according to conditions: Port, Offshore, and Weather. MARPA target tracking allows simultaneous monitoring of up to 10 selected collision threats. Customizable guard zones can also be configured to trigger alarms.

Technical specifications and product range positioning

With a diameter of 510 mm and a height of 223 mm, the radome weighs 5.9 kg. It is IPX6 waterproof certified and operates on a 10.5 to 31.2V DC power supply, making it compatible with both 12V and 24V systems. Power consumption is 18W in typical operation and 20W at maximum. The HALO20 is the entry-level model in the B&G dome radar range. Unlike the higher-end HALO20+ model, it does not feature VelocityTrack™ Doppler technology, Dual Range operation, or accelerated rotation speed of 60 RPM.

Expert opinion

« B&G Solid-State Technology: Reliability and Performance for Cruising »

The B&G HALO20 radar democratizes pulse compression technology, previously reserved for more expensive systems. For sailboats and powerboats, the advantage is twofold: very low power consumption (3.9 W standby) and the Instant On™ function, which makes the radar immediately operational, a critical safety factor. Its ability to provide a clear image at very short range while monitoring the horizon up to 48 nautical miles is a game-changer for coastal and offshore navigation. The rapid 60 RPM rotation is particularly effective for collision avoidance in high-traffic areas. Ethernet integration is simple and reliable, making the HALO20 a logical and high-performance upgrade for any B&G navigation system.

Frequently Asked Questions

Need help? Contact us

Can the B&G HALO20 radar be installed alongside a conventional pulse radar?

No, the HALO20 radar should not be installed on the same plane as a conventional pulse radar. The pulse radar must be put in STBY or OFF mode when the HALO20 radar is operating.

What is the required supply voltage for the B&G HALO20 radar?

The B&G HALO20 radar requires a DC power supply of 10.5 to 31.2 V with reverse polarity protection.

Does the B&G HALO20 radar require a warm-up time?

No, the B&G HALO20 radar features Instant On™ technology and does not require warm-up time as it is fully solid-state (no magnetron).

Is the B&G HALO20 radar waterproof?

Yes, the B&G HALO20 radar is waterproof to IPX6 standard.

What is the transmission frequency of the B&G HALO20 radar?

The transmission frequency of the B&G HALO20 radar is X-band, from 9.4 to 9.5 GHz.

What type of cable is used for the B&G HALO20 radar connection?

The B&G HALO20 radar uses a connection cable with an RJ45 connector.

What is the maximum length of the interconnection cable for the B&G HALO20 radar?

The maximum length of the interconnection cable for the B&G HALO20 radar is 30 meters (98.5 feet) and is available as an option.

Does the HALO20 radar require a warm-up time?

No, the HALO20 radar uses Instant On™ solid-state technology, which means it is ready to operate instantly without any warm-up time.

What is the power consumption of the B&G HALO20 radar?

The power consumption of the HALO20 radar is 17 to 29 W in operation (depending on range and mode) and approximately 3.9 W in standby mode (at 13.8 V DC).

Is the B&G HALO20 radar waterproof?

Yes, the B&G HALO20 radar is IPX6 certified, which means it is protected against powerful water jets.

How to install the HALO20 radar on my boat?

The installation of the HALO20 radar requires careful adherence to the installation manual instructions. It is important to verify the correct orientation with the provided mounting template, ensure sufficient clearance around the radar, and use the appropriate bolts for the mounting surface.

Can the HALO20 radar interfere with other electronic equipment on board?

To avoid interference, it is recommended not to install the HALO20 radar on the same plane as a conventional pulse radar. Additionally, it is advisable to maintain a minimum distance of 0.7 m (2.3 ft) between the radar and the vessel's compass.

Where can I find the installation manual for the HALO20 radar?

The installation manual for the HALO20 radar is included with the product. It is also available in your Skysat customer account, and on this product page.
