HALO20 Radar

The HALO20’s solid-state technology delivers several key benefits:

Instant-on operation: Thanks to Instant On™ technology, the radar is ready for use immediately, with no warm-up time.Increased reliability: The absence of a magnetron—a wear part in traditional radars—significantly extends product lifespan and reliability.Low power draw: It consumes very little energy, making it ideal for mid-sized sailboats and powerboats.Safety: It emits no harmful radiation, with a 0-meter safety distance for the public, allowing flexible and safe installation.

The SIMRAD HALO20 radar is designed to integrate seamlessly with SIMRAD multifunction displays (MFD), including the NSS evo2/evo3 and NSO evo2/evo3 series. Connection is via the Ethernet network.

The HALO20 radar is compatible with 12V and 24V DC electrical systems, allowing it to be installed on the vast majority of recreational boats.

The SIMRAD HALO20 radar provides reliable detection at short and medium range, with a maximum range of up to 24 nautical miles.

No, the HALO20 is the entry-level model in the range and does not include the Doppler VelocityTrack™ target tracking feature. To access this technology, which colors targets approaching or moving away, you must choose higher-end models such as the HALO20+ or HALO24.

The HALO20 radome weighs 5.9 kg (excluding the cable). Its lightweight design makes it particularly suitable for sailboats, where weight aloft is a critical factor, as well as for small motorboats.

Yes, absolutely. The HALO20 radar has an IPX6 waterproof rating. This means it is protected against powerful water jets from all directions, ensuring its robustness and durability in harsh marine conditions.

No, there is no danger. Thanks to its low-emission solid-state technology, the safety distance for the public is 0 meters. You can therefore install it anywhere without risk to the crew.

To avoid any magnetic interference that could distort the readings of your magnetic compass, it is essential to maintain a minimum distance of 0.7 meters (2.3 feet) between the HALO20 radar dome and any magnetic compass instrument.

The connection between the HALO20 radar and a compatible Simrad multifunction display is made via a 100Base-T Ethernet link. This ensures fast, stable, and reliable data transfer for smooth radar information display.

The HALO20 radar is designed to withstand varied weather conditions. Its operating temperature range is from -25 °C to +55 °C (-13 °F to +130 °F).

The maximum length of the optional interconnect cable to connect the radar to your system is 30 meters (98.5 feet), providing significant flexibility for installation on different types of boats.

For optimal performance, it is crucial to choose a mounting location that provides the radome with a clear 360° view. Install it as high as possible to maximize range and ensure there are no obstacles (masts, antennas, etc.) in the beam’s sweep path.

No, it is strongly discouraged to install the HALO20 radar in the same beam field as a pulse radar (magnetron type). To avoid interference and potential damage, the pulse radar must be turned off or in standby mode when the HALO20 is operating.

The HALO20 is a compact radar. Its radome measures 20 inches in diameter, approximately 51 cm. This reduced size makes it easier to install on small to mid-sized boats where space may be limited.

Yes, absolutely. With its pulse compression technology and good target separation, the HALO20 excels in short- to mid-range detection. It is therefore particularly effective for coastal navigation, harbour entry and exit manoeuvres, and hazard monitoring in reduced visibility.

Yes, the HALO20 radar is designed to work with SIMRAD navigation systems. It connects via a standard 100Base-T Ethernet protocol, enabling simple integration with SIMRAD displays from the NSS, NSO, and NSE series, as well as compatible Ethernet switches. For optimal compatibility, ensure your display has the latest software version installed. The radar is also compatible with Lowrance and B&G systems using the same Ethernet network.

The HALO20 radar’s electrical consumption varies depending on the selected range and mode. In normal operation, it ranges from 17 to 29 W at a 13.8 V DC supply. In standby mode, consumption drops to just 3.9 W. This low power draw is a key benefit of solid-state technology without a magnetron, particularly valued on sailboats and vessels with limited power availability.

No, the HALO20 radar does not require any warm-up time. Thanks to its Instant On™ technology and the absence of a magnetron (design using only semiconductors), the radar is operational immediately after power-on. This is a significant advantage over traditional magnetron radars, which may require several minutes of preheating before emitting.

Yes, the HALO20 radar has an IPX6 waterproof rating. This means it is protected against powerful water jets and breaking waves, making it perfectly suited for marine environments. It can withstand heavy rain and spray without damage. Its operating temperature range is from -25 °C to +55 °C.

Installation of the HALO20 radar can be carried out by an experienced boat owner, but it requires marine electrical and mechanical mounting skills. The SIMRAD installation manual details the steps: mounting on mast or pedestal, connection of the interconnection cable (Ethernet 100Base-T), power supply connection (12/24 V DC), and the yellow control wire. It is imperative to respect safety distances (0 m for the public) and ensure the radar has a clear 360° view. If in doubt, it is recommended to use a professional installer.

Yes, but a minimum distance of 0.7 metres (2.3 feet) must be maintained between the HALO20 radar and the vessel’s compass instruments. This distance is required to prevent magnetic interference that could affect compass accuracy. During installation, ensure this safety distance is respected to guarantee proper operation of your navigation instruments.

The HALO20 radar uses a standard 100Base-T Ethernet protocol, making it potentially compatible with other navigation systems using the same network, such as Lowrance and B&G displays (Navico group brands). However, for full integration and access to all features (such as range and mode control), it is best used with a SIMRAD display. Check specific compatibility with your display manufacturer.

The HALO20 radar is typically supplied with a standard-length interconnect cable. However, the included cable length may vary depending on configurations and dealers. The technical documentation states that the maximum interconnect cable length is 30 meters (98.5 feet) and that longer cables are available as an option. We recommend checking the included accessories at the time of purchase or contacting our customer service for further details.

The HALO20 radar primarily connects via an Ethernet network (100Base-T) for radar data transfer (video and control). It is not directly compatible with the NMEA 2000 protocol for radar image transmission. However, the display it is connected to (e.g., a SIMRAD NSS) may itself be connected to an NMEA 2000 network to share position, speed, and heading data with the radar. The radar can then use this information to enhance target display and tracking.

Yes, the HALO20 radar can be installed on a tilted mast. The SIMRAD documentation even recommends, for powerboats with a strongly sloped roof, tilting the antenna nose forward to compensate for the vessel’s trim. The goal is to ensure a 360° view as clear as possible and to optimize target detection. It is important to choose a mounting location with an unobstructed view of any obstacles.
