Püsiv alusantenn MB-BA197

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 pedestal is its fixed, one-piece design with no moving parts. Unlike adjustable or tiltable ball-joint mounts, it eliminates any risk of loosening due to vibrations or marine stresses, providing absolute reliability and optimal compactness.

This transom mount 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 MB-BA197 fixed base is ensured by several aspects of its design and construction:

One-piece design: This integrated structure guarantees superior mechanical resistance, 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 the effects of marine stresses or engine vibrations.Permanent and secure anchoring: Its installation by direct screwing onto the deck ensures permanent and very secure anchoring, contributing to the overall stability of the antenna.Maintenance of vertical axis: It keeps the antenna strictly vertical, which is essential to maintain signal transmission and reception performance over time.These combined features prioritize robustness and stability, essential for reliable and long-lasting use at sea.

The advantages of a fixed shaft bracket 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 base is designed to optimize the performance and reliability of your maritime communication system in several ways:

Strict vertical alignment: It ensures the antenna is held in a strict vertical axis. This stability is essential to guarantee optimal transmission and reception of VHF, ASN, and AIS signals, particularly for fixed stations transmitting at 25 W.Superior mechanical resistance: Its one-piece design provides exceptional robustness. It effectively resists vibrations, impacts, and extreme weather conditions encountered at sea, thus protecting the antenna's integrity.Absolute reliability: The complete absence of moving parts, unlike adjustable mounts, eliminates any risk of loosening due to marine stresses or engine vibrations. This ensures permanent and secure antenna mounting, reducing the risk of failure or signal loss.Secure anchoring: Installation by direct screwing onto flat surfaces of the vessel (deck, console, helm roof) ensures permanent and reliable anchoring, essential for the durability of the installation 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 fixed strut is installed by screwing it directly onto a flat surface of the boat. This method ensures permanent and secure anchoring.

The base can be mounted on various flat surfaces of the boat, such as the deck, the console, or the roof of the bridge, provided these surfaces are perfectly level.

Yes, it is imperative to install the MB-BA197 mount on a perfectly horizontal surface. Its fixed design does not allow adjusting the antenna angle. For sloped surfaces, a swivel mount would be required.

During installation of the fixed base MB-BA197, the coaxial cable is routed and secured by 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 holds the cable securely 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 screwing fixation and robust design ensure a durable and secure anchoring 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 pilothouse roof. For correct and secure installation, you will need fasteners suitable for the material of your mounting support (for example, stainless steel screws for the marine environment).

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

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

This base is designed to support whip antennas 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 accept 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 fixed MB-BA197 base is designed to secure the passage of the coaxial cable (with an impedance of 50 Ω) from an antenna to various marine communication devices. It is compatible with antennas intended for transmitting and receiving VHF, ASN (Digital Selective Calling), and AIS (Automatic Identification System) signals.

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

Fixed VHF stations, such as the Icom IC-M510E EVO, for voice communications and ASN 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 base itself provides mechanical support and cable routing, while the antenna and connected devices handle the specific signals.

The fixed base MB-BA197 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 mount is a fixed model that holds the antenna in a strict vertical axis. If your installation requires angle adjustment on a sloped surface, it is recommended to opt for a 4-axis articulated ball joint from the same range.
