36m VMHU mast cable

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

This cable is exclusively compatible with B&G VMHU (Vertical Masthead Units). It is not designed for use with other types of B&G sensors (like classic MHUs) or sensors from other brands, as connectors and electrical specifications may differ.

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

It is strongly advised not to cut this cable. Modifying 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 offer a continuous and reliable connection, without weak points.

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

Using a single, continuous 36-meter cable offers several key advantages:

Increased reliability: It eliminates intermediate splices and connectors, which are potential sources of failure, corrosion, and signal loss.Signal quality: A continuous connection ensures more stable and accurate data transmission.Simplified installation: There is no need to make mid-run splices or waterproof connections.

For optimal installation, it is recommended to:

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

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

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

Although technically possible with a waterproof junction box and appropriate connections, it is not recommended to extend this cable. The purpose of this great length is precisely to avoid splices. If a longer length is necessary, it is best to consult B&G for alternative solutions.

Yes, the cable with reference BGH030006 is an official product and an original part from the B&G brand, ensuring optimal compatibility and quality with the brand's equipment.

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

A service loop is an extra length of cable that is deliberately left at the base of the mast. It is very important because it allows for de-masting or maintenance operations on the 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 systematically shielded. The shielding protects sensitive data signals from electromagnetic interference (coming from, for example, VHF, radar, or power cables), which ensures the accuracy of wind readings.

This cable is equipped with a specific molded connector at one end, designed to plug watertight directly into the VMHU sensor at the masthead. The other end is usually prepared to be connected 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 use a professional installer or a qualified marine technician.

Yes, the function of this cable is to transmit the analog or digital signals generated by the VMHU wind sensor. These signals correspond to the apparent wind speed and direction. They are then interpreted by the processor of your navigation system.

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 puller (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.
