VHF antenna Location | Furuno FA-100 guide

1.1.2VHF antenna Location

Location of the mandatory AIS VHF-antenna should be carefully considered. Digital communication is more sensitive than analog/voice communication to interference created by reflections in obstructions like masts and booms. It may be necessary to relocate the VHF radiotelephone antenna to minimize interference effects.

To minimise interference effects, the following guidelines apply:

•The AIS VHF antenna should be placed in an elevated position that is as free as possible with a minimum of 0.5 meters in the horizontal direction from constructions made of conductive materials. The antenna should not be installed close to any large vertical obstruction. The objective for the AIS VHF antenna is to see the horizon freely through 360 degrees.

•The AIS VHF antenna should be installed safely away from interfering high-power energy sources like radar and other transmitting radio antennas, preferably at least 3 meters away from and out of the transmitting beam.

•There should not be more than one antenna on the same plane. The AIS VHF antenna should be mounted directly above or below the ship’s primary VHF radiotelephone antenna, with no horizontal separation and with a minimum of 2.8 meters vertical separation. If it is located on the same plane as other antennas, the distance apart should be at least 10 meters.

Cabling

•The cable should be kept as short as possible to minimize signal attenuation. Coaxial cables equal to or better than RG10U/Y are recommended.

•All outdoor installed connectors on coaxial cables should be fitted with preventive isolation such as vulcanizing tape to protect against water penetration into the antenna cable.

•Coaxial cables should be installed in separate signal cable channels/tubes and at least 10 cm away from power supply cables. Crossing of cables should be done at right angles (90°). The minimum bend radius of the coaxial cable should be 5 times the cable's outer diameter.

•Install the VHF whip antenna referring to the outline drawing at the back of this manual. Separate this antenna from other VHF radiotelephone antennas as shown on the next page to prevent interference to the FA-100.

FA-100 specifications

The Furuno FA-100 is a sophisticated maritime communication and navigation technology designed to enhance safety and situational awareness for vessels operating in both commercial and recreational capacities. The device is particularly popular among the fishing, cargo, and passenger transport industries, where precise navigation and reliable communication are paramount.

One of the standout features of the FA-100 is its AIS (Automatic Identification System) capabilities. This technology enables vessels to automatically send and receive information about their position, course, and speed, significantly improving situational awareness by allowing ships to detect and track nearby vessels. With its dual-channel AIS receiver, the FA-100 can monitor a wide range of traffic in busy shipping lanes, making it easier for operators to avoid potential collisions and navigate safely.

The FA-100 boasts robust GPS functionality, providing accurate position data that is critical for navigation. This positioning system is enhanced by the use of advanced satellite technology, ensuring reliable location tracking even in challenging environments such as dense urban areas or adverse weather conditions. With its high update rate, navigators receive timely information, allowing for informed decision-making.

Additionally, the Furuno FA-100 includes various interface options, facilitating the integration with other onboard systems. The device can connect seamlessly with radar, chart plotters, and other navigation equipment, creating a cohesive and comprehensive navigational network. This interoperability enhances overall situational awareness and simplifies vessel operation by providing a unified interface for monitoring and controlling different systems.

Durability is another essential aspect of the FA-100, as it is built to withstand harsh marine environments. Its weatherproof design ensures reliable performance even under extreme conditions, while the user-friendly interface allows operators to access and interpret data quickly and efficiently. The intuitive display is designed to provide clear and concise information, making it suitable for users of varying experience levels.

Overall, the Furuno FA-100 is a highly effective tool for marine navigation and communication. With its advanced AIS capabilities, reliable GPS, extensive interfacing options, and rugged design, it stands out as an essential device for enhancing the safety and efficiency of maritime operations.
