Purpose and compatibility

The shark fin antenna housing is designed for the roofs of BMW F-series models, such as the F20, F21, F31, and F34. The construction is tailored to the factory roof contour and antenna mounting point, which facilitates proper seating of the component and ensures a tight seal around the mounting hole. As a result, the housing serves as a functional addition to the existing antenna module without the need for any structural modifications to the bodywork.

Color and finish Estoril Blau Metallic – B45

The finish in Estoril Blau Metallic – B45 is characteristic of sport-configured BMW units, especially in trim lines with a dynamic character. The metallic paint coating ensures:

• color consistency with the factory body paint,
• aesthetic alignment with the roofline and glazing,
• a modern, dynamic look characteristic of sporty BMW configurations.

Thanks to this, the antenna housing does not look like an aftermarket add-on, but rather an integral part of the body design.

Design characteristics and installation

The shark fin antenna housing acts as an external cover for the antenna module, protecting it from weather conditions and mechanical damage. The shape, optimized for airflow, reduces turbulence on the roof and fits into the vehicle's aerodynamic line. Installation involves seating the housing onto the existing antenna base, maintaining the correct alignment relative to the vehicle's axis.

The item is used, which in practice means it comes from disassembly and may show signs of wear typical of aftermarket components. For many users, this is a cost-effective solution that allows for maintaining the original look of the car on a reasonable budget, especially in the case of post-accident repairs or replacing a damaged housing.

Practical application and benefits

Using this antenna housing in Estoril Blau Metallic – B45 is particularly beneficial when:

• it is necessary to replace a damaged or cracked roof antenna housing,
• after body and paint repairs, it is necessary to restore a consistent roof appearance,
• the user wants to maintain the original character of BMW equipment without using universal replacements.

The original form and fit to the roofline translate into an aesthetic final result, which is particularly important in premium class vehicles, where body details have a significant impact on the overall perception of the car.

Configuration expansion and component selection

If you are planning a comprehensive repair or upgrade of the roof area in your BMW and need other components from the same group, such as additional covers, roof moldings, or other accessories mounted on the upper part of the body, check the available parts in the Other BMW category.

When planning upgrades or repairs to the bodywork and retrofitting the car with elements similar to sports versions, it is also worth expanding your knowledge about the structural differences between standard variants and more advanced ones.
