Állandó antennaaljzat MB-BA197

The MB-BA197 fixed antenna base is a rigid, one-piece mounting bracket specifically designed for permanent and secure installation of marine 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 socket 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, impacts, 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 highly secure anchoring, contributing to the overall stability of the antenna.Maintenance of the vertical axis: It keeps the antenna in a strict vertical axis, which is essential to maintain 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 shaft coupling are numerous. It provides absolute reliability by eliminating any risk of the clamping handle loosening due to marine stresses or engine vibrations. Its one-piece design ensures superior mechanical strength and greater compactness, prioritizing stability and durability.

The MB-BA197 fixed base 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 axis. This stability is essential to guarantee optimal transmission and reception performance for 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, shocks, and extreme weather conditions encountered at sea, thus protecting the integrity of the antenna.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 attachment of the antenna, 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 thru-hull fitting is installed by screwing it directly onto a flat surface of the boat. This method ensures permanent and secure anchoring.

The mounting base can be installed on various flat surfaces of the vessel, such as the deck, console, or wheelhouse roof, provided these surfaces are perfectly level.

Yes, it is essential to install the MB-BA197 base on a perfectly level surface. Its fixed design does not allow for adjusting the antenna angle. For sloped surfaces, you would need to opt for a swivel base.

During installation of the fixed MB-BA197 base, 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 plane. 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 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 helm roof. For correct and secure mounting, you will need fasteners suitable for the material of your mounting surface (e.g., 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 antenna whips operating on standard maritime frequency bands. It is compatible with marine communication antennas requiring a fixed and vertical mount.

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

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 base is designed to secure the passage of the coaxial cable (with a 50 Ω impedance) from an antenna to various marine communication devices. It is compatible with antennas intended for transmitting and receiving VHF, DSC (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 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 base itself provides mechanical support and cable routing, while the antenna and connected equipment 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, we recommend using a 4-axis articulated ball joint from the same range.
