Purpose and function of the component

The presented BMW roof antenna housing is an "empty housing," meaning it is an outer shell without internal electronics. Its purpose is to cover the actual antenna module and provide the aerodynamic, factory-standard shape characteristic of BMW F-series models. Its placement at the rear of the roof promotes even signal distribution and maintains the original body lines.

This component is suitable for cases where the factory housing has suffered mechanical damage or cracking, while the antenna module remains functional. By using an original design, it is possible to transfer the existing electronics to the new shell without interfering with the vehicle's wiring.

Color and visual fit

The housing is finished in Seaside Blue Metallic (C1R), which allows for consistency with the vehicle's factory paint in this color. The metallic blue paint provides a characteristic shine and blends well with the roofline and the rear part of the body.

Thanks to the factory finish, the component does not require additional painting if installed on a car with the same color code. This solution reduces repair time and allows for the quick restoration of the roof's aesthetics after the original housing has been damaged.

Installation on the rear roof section

The housing is designed for installation in the rear roof area, in place of the factory shark-fin antenna. The shell construction is adapted to the standard mounting hole and the shape of the antenna base used in BMW F-series vehicles. This ensures:

• proper adhesion to the roof panel,
• adequate sealing when using the correct gaskets,
• original antenna geometry relative to the body lines.

This item is used, which in practice means it has been removed from a vehicle and may show signs of wear typical of aftermarket parts, while maintaining its structural functionality.

Application in BMW vehicles

The roof antenna housing in Seaside Blue Metallic is dedicated to selected BMW F-series models, particularly the F20/F21 compact hatchbacks and the F31 touring. Using an original housing allows you to maintain stylistic consistency with other body components and avoid fitment issues that often arise with low-quality replacements.

This solution is particularly beneficial for accident repairs, bodywork and paint corrections, or restoring a vehicle to a near-factory state when maintaining the characteristic look of the BMW roof antenna is a priority.

Benefits of choosing an original housing

By choosing this roof antenna housing, you gain:

• original shape and fit for the BMW F-series roof,
• Seaside Blue Metallic paint matching the factory color,
• the ability to reuse the existing antenna module,
• aesthetic restoration of the rear roof section after damage.

This is a practical solution for users who want to maintain the original character of the car while optimizing repair costs by using a pre-owned body component.
