The MB-BA197 fixed antenna base is a rigid, one-piece mounting bracket specifically designed for permanent and secure installation of maritime communication antennas. It is distributed by Icom and ensures stable anchoring on flat surfaces of the vessel.

The main feature of the MB-BA197 strut is its fixed, one-piece design with no moving parts. Unlike adjustable or tiltable gimbal mounts, it eliminates any risk of loosening due to vibrations or marine stresses, providing absolute reliability and optimal compactness.

This thru-hull fitting is specifically designed for boats with perfectly horizontal mounting surfaces. Its design ensures superior mechanical resistance to vibrations, shocks, and extreme weather conditions encountered at sea, making it ideal for rigorous marine use.

The long-term reliability of the fixed MB-BA197 base is ensured by several aspects of its design and construction:

One-piece design: This integrated structure guarantees superior mechanical strength, capable of effectively withstanding vibrations, shocks, and extreme weather conditions typical of the marine environment.No moving parts: Unlike adjustable gimbal mounts, the MB-BA197 base has no moving parts. This eliminates any risk of loosening of the clamping handle, a potential failure point under marine stresses or engine vibrations.Permanent and secure anchoring: Its installation by direct screwing onto the deck ensures permanent and highly secure anchoring, contributing to the overall stability of the antenna.Maintaining vertical alignment: It keeps the antenna in a strict vertical axis, which is essential to preserve the transmission and reception performance of signals over time.These combined features prioritize robustness and stability, essential for reliable and long-lasting use at sea.

The advantages of a fixed base are numerous. It offers absolute reliability by eliminating any risk of loosening of the clamping handle due to marine stresses or engine vibrations. Its one-piece design ensures superior mechanical strength and greater compactness, prioritizing stability and durability.

The fixed MB-BA197 mount is designed to optimize the performance and reliability of your marine communication system in several ways:

Maintains a strict vertical axis: It ensures the antenna is held in a perfectly vertical position. This stability is essential for optimal VHF, ASN, and AIS signal transmission and reception, particularly for fixed stations transmitting at 25 W.Superior mechanical resistance: Its one-piece design provides exceptional robustness. It effectively withstands vibrations, shocks, and extreme weather conditions encountered at sea, protecting the antenna's integrity.Reliability: The complete absence of moving parts, unlike adjustable mounts, eliminates any risk of loosening due to marine stresses or engine vibrations. This guarantees a permanent and secure antenna attachment, reducing the risk of failure or signal loss.Secure anchoring: Direct screwing onto flat surfaces of the vessel (deck, console, helm roof) ensures a permanent and reliable anchor point, essential for long-term installation durability and consistent communications.

Yes, the MB-BA197 fixed antenna base is an accessory distributed by Icom, a brand recognized in the field of marine communication equipment.

The MB-BA197 thru-hull fitting is installed by screwing it directly onto a flat surface of the boat. This method ensures permanent and secure anchoring.

The transducer can be mounted on various flat surfaces of the vessel, such as the deck, console, or coachroof, provided these surfaces are perfectly level.

Yes, the MB-BA197 base must be installed on a perfectly level surface. Its fixed design does not allow for antenna angle adjustment. For sloped surfaces, a swivel base should be considered.

When installing the fixed base MB-BA197, the coaxial cable is routed and secured thanks to its design for direct screwing onto a flat surface of the vessel, such as the deck. The coaxial cable, with an impedance of 50 Ω, is typically routed through the deck. Once firmly screwed in place, the base helps keep the cable in position and protects its entry point, ensuring a stable and reliable connection to communication equipment or an AIS transponder.

Yes, the MB-BA197 base is designed for permanent installation. Its direct screw-fixing and robust design ensure a durable and secure mounting of the antenna on the vessel.

The MB-BA197 fixed antenna base is designed to be installed by direct screwing onto a flat and horizontal surface of the vessel, such as the deck, console, or helm roof. For correct and secure fastening, you will need fasteners suitable for the material of your mounting support (e.g., stainless steel screws for the marine environment).

It is essential to select screws of appropriate length and diameter to ensure optimal mechanical holding. Additionally, it is strongly recommended to use a marine-grade sealant at the fastening points to ensure waterproofing and protect against water infiltration.

The MB-BA197 mount is sized to accommodate antenna whips operating on standard maritime frequency bands. It is compatible with marine communication antennas requiring a fixed and vertical support.

This deck plate is designed to support antenna whips operating on standard maritime frequency bands, such as those used for VHF transmission and reception (156.025 – 161.425 MHz), ASN (156.525 MHz) or AIS.

Yes, the MB-BA197 base is designed to accommodate the antenna whips required for VHF communications, ASN (Digital Selective Calling) systems, and AIS (Automatic Identification System) transponders.

The MB-BA197 fixed antenna base is designed to simplify the routing and installation of an antenna using a coaxial cable with an impedance of 50 Ω. This impedance is the standard for VHF, ASN, and AIS maritime communication systems, ensuring optimal compatibility with most communication equipment and AIS transponders.

The MB-BA197 fixed mount is designed to secure the coaxial cable (with 50 Ω impedance) from an antenna to various marine communication devices. It is compatible with antennas used for VHF, DSC (Digital Selective Calling), and AIS (Automatic Identification System) signal transmission and reception.

This means an antenna mounted on this mount can be connected to:

Fixed VHF stations, such as the Icom IC-M510E EVO, for voice communications and DSC functions.

Class B AIS transponders, such as the MA-510TR, for receiving and transmitting ship identification and position data.

More generally, any marine communication equipment requiring an antenna for standard maritime frequency bands (156.025–161.425 MHz for transmission and 156.500–162.000 MHz for reception).

The mount itself provides mechanical support and cable routing, while the antenna and connected devices handle the specific signals.

The MB-BA197 fixed base is designed to accommodate standard marine antenna whips. It features a standard 1-inch - 14 TPI (threads per inch) thread. This thread type is universally used in the marine industry, ensuring mechanical compatibility with the vast majority of VHF, ASN, and AIS antennas available on the market.

No, the MB-BA197 base is a fixed model that keeps the antenna in a strictly vertical axis. If your installation requires angle adjustment on a sloped surface, consider using a 4-axis articulated ball joint from the same range.
