MOUNTING

1.1 Scanner Unit

Mounting considerations

•The scanner unit is generally installed either on top of the wheelhouse or on the radar mast, on a suitable platform. Locate the scanner unit where there is a good all-round view.

•No funnel, mast or derrick should be within the vertical beamwidth of the scan- ner in the bow direction, especially zero degrees ± 5° , to prevent blind sectors and false echoes on the radar picture.

•It is rarely possible to place the scanner unit where a completely clear view in all directions is available. Thus, you should determine the angular width and relative bearing of any shadow sectors for their influence on the radar at the first opportunity after fitting.

•Locate the antenna of a direction finder clear of the scanner unit to prevent interference to the direction finder. A separation of more than two meters is recommended.

•To lessen the chance of picking up electrical interference, avoid where possible routing the signal cable near other onboard electrical equipment. Also avoid running the cable in parallel with power cables.

•A magnetic compass will be affected if placed too close to the scanner unit. Observe the following minimum compass safe distances to prevent deviation of a magnetic compass: Standard compass, 3.90 m, Steering compass, 2.30 m.

•Do not paint the radiator aperture, to ensure proper emission of the radar waves.

•The signal cable run between the scanner and the display is available in lengths of 15 m (standard), 20 m, 30 m and 60 m. Whatever length is used it must be unbroken; namely, no splicing allowed.

•Deposits and fumes from a funnel or other exhaust vent can adversely affect

the aerial performance and hot gases may distort the radiator portion. The scan- ner unit must not be mounted where the temperature is more than 70° C.

•The scanner base is made of cast aluminum. To prevent electrolytic corrosion of the scanner base, use the seal washers and corrosion-proof rubber mat and ground the unit with the ground wire (supplied).

•Leave sufficient space around the unit for maintenance and servicing. See the scanner unit outline drawing for recommended maintenance space.

FR-2155 specifications

The Furuno FR-2155 is a state-of-the-art marine radar system known for its reliability, exceptional performance, and user-friendly interface. This long-range radar is specifically designed for commercial and recreational vessels, providing operators with crucial situational awareness on the water. With its robust features and advanced technology, the FR-2155 ensures maritime safety and efficiency, making it a preferred choice among navigators and fleet operators.

One of the standout features of the FR-2155 is its high-definition display, which offers a crystal-clear view of radar images. The 15-inch LCD screen provides an easy-to-read presentation of targets, weather conditions, and navigational information. The display is designed to be sunlight-readable, ensuring clear visibility even in bright conditions.

The radar utilizes Furuno's advanced Doppler technology, which allows users to track moving targets accurately. This feature enhances collision avoidance efforts by providing real-time information on the speed and direction of approaching vessels, making it easier to assess potential risks. Moreover, the FR-2155 incorporates an Automatic Radar Plotting Aid (ARPA) function that automatically tracks up to 50 targets, allowing operators to concentrate on navigating rather than manually monitoring multiple targets.

Another remarkable characteristic of the Furuno FR-2155 is its ability to operate in various weather conditions. The radar system can filter out rain, sea clutter, and other interference, ensuring a clear image of surrounding objects. This feature is especially beneficial in adverse weather, where visibility is often compromised, thereby enhancing safety during challenging navigation scenarios.

Connectivity is crucial in modern maritime operations, and the FR-2155 excels in this regard by offering various integration options for onboard systems. It can seamlessly connect with GPS, AIS, and other navigation systems, providing a comprehensive overview of the vessel's environment. Additionally, the radar is capable of outputting data to chart plotters and electronic displays, consolidating critical information for the crew.

In terms of installation, the Furuno FR-2155 is designed for versatility. Its compact design allows for flexible mounting options, accommodating different vessel layouts without compromising performance. The radar also features a powerful magnetron that ensures long-range detection capabilities, effectively covering vast areas of water.

In summary, the Furuno FR-2155 marine radar system stands out due to its high-definition display, Doppler technology, automatic target tracking, and excellent clutter rejection. Its ability to integrate seamlessly with other navigation tools and its user-friendly design make it an invaluable asset for any vessel, ensuring safety and efficiency on the water. For those looking for a reliable radar solution, the FR-2155 is certainly worth considering.
