VMHU mastkabeļa kabelis, 36 m

This cable, part number BGH030006, is specifically designed to connect a VMHU (Vertical Masthead Unit) wind transducer from B&G to the boat's navigation system. It ensures the transmission of wind data (speed and angle) from the masthead sensor to the instruments.

This cable is exclusively compatible with B&G vertical masthead units (VMHU). It is not designed for use with other B&G sensor types (such as standard MHU units) or sensors from other brands, as the connectors and electrical specifications may differ.

The length of this mast cable is 36 meters (approximately 118 feet). This long length is designed for sailboats with tall masts, allowing direct connection without a splice.

It is strongly discouraged to cut this cable. Trimming its length by cutting would require a splice that could compromise waterproofing and signal quality. One of the main advantages of this cable is precisely to provide a continuous and reliable connection, without any weak point.

VMHU stands for Vertical Masthead Unit. This is a type of wind sensor (vane anemometer) designed by B&G, mounted vertically at the top of the mast and renowned for its high accuracy.

Using a single-piece 36-meter cable offers several major advantages:

Increased reliability: It eliminates intermediate junctions and connectors, which are potential sources of failures, corrosion, and signal loss.Signal quality: A continuous connection ensures more stable and accurate data transmission.Simplified installation: No need to perform splices or mid-span waterproof connections.

For optimal installation, it is recommended to:

Use a conduit or cable gland if the mast is equipped with one to protect the cable. Secure the cable to prevent it from slapping against the mast wall (chafing) and generating noise. Avoid sharp bends and contact with moving sheets. Leave a service loop (some slack) at the base of the mast to facilitate future maintenance.

Yes, as an official B&G product designed for masthead installation, this cable is made with high-quality materials engineered to withstand harsh marine conditions, including UV exposure, salt, humidity, and temperature fluctuations.

No, this cable does not connect directly to a display. It plugs into an interface or central processor (such as a B&G H5000 processor or a dedicated junction box) that processes the sensor’s raw data before distributing it over the NMEA 2000 or NMEA 0183 network to the various displays.

While technically possible with a watertight junction box and proper connections, it is not recommended to extend this cable. The purpose of this long length is precisely to avoid junctions. If a longer length is required, it is better to consult B&G for alternative solutions.

Yes, cable with reference BGH030006 is an official B&G product and genuine manufacturer part, ensuring compatibility and optimal quality with B&G equipment.

No, this cable is not compatible. The 213 is an MHU (Masthead Unit), not a VMHU (Vertical Masthead Unit). They use different connectors and potentially different internal wiring. You must use the cable specified for your sensor model.

A service loop is an extra length of cable deliberately left at the base of the mast. It is very important because it allows you to unstep the mast or perform maintenance on connections at the base of the mast without having to pull on the cable or disconnect it at the masthead.

Yes, data cables for navigation instruments like this one are always shielded. The shielding protects sensitive data signals from electromagnetic interference (e.g., from VHF, radar, or power cables), ensuring accurate wind readings.

This cable is fitted with a molded connector at one end, designed to plug directly and waterproof onto the VMHU sensor at the masthead. The other end is typically prepared for connection to a junction box or a B&G processor.

Installing a mast cable involves working at height and making critical electrical connections for your navigation system. For safety and reliability reasons, it is strongly recommended to hire a professional installer or a qualified marine technician.

Yes, this cable’s function is to transmit the analog or digital signals generated by the VMHU wind transducer / vane anemometer. These signals correspond to apparent wind speed and direction. They are then processed by your navigation system’s processor.

Yes, this cable is designed to integrate seamlessly with B&G systems, including the H5000 processor range. It connects to the dedicated wind sensor input on the processor or via a system junction box.

This depends on the existing installation. If an old cable is already in place and can be used as a pull-wire (messenger), it is sometimes possible to replace it without unstepping the mast. However, for a new, clean, and secure installation, unstepping the mast is often the simplest and safest method.
