Purpose and compatibility with BMW models

The presented "shark" housing is an original BMW component, designed for modern G-series models such as the G20, G21, G30, or G11. Thanks to its factory-spec geometry, it ensures a perfect fit to the roof surface and correct positioning in the rear zone of the vehicle. This solution is particularly useful when replacing a damaged cover or restoring a car to the manufacturer's original specifications.

Portimao Blue Metallic C31 color and aesthetic value

The Portimao Blue Metallic C31 color is a distinctive, dynamic shade of blue used in current BMW generations, often found on versions with a sportier character. Using a factory-painted antenna cover in this color allows you to:

• maintain color consistency across the entire roof and pillars,
• minimize shade differences compared to the original body paint,
• preserve the modern, characteristic look of the roofline.

For users who pay attention to body details, a color-matched antenna cover is an important visual element that influences the overall perception of the vehicle.

Technical function and role in the antenna system

The roof antenna cover primarily serves a protective and aerodynamic function. It shields the antenna module from external factors such as moisture or dirt, while its shape, matched to the roof, reduces air turbulence. Proper placement in the rear part of the vehicle promotes stable antenna performance and maintains correct signal reception parameters.

Thanks to a design compliant with factory BMW standards, the housing allows for installation in place of the original part without the need for modifications to the roof or antenna base. This is a beneficial solution for both post-accident repairs and replacing the component for aesthetic reasons.

Characteristics of the used component

As a used part, the roof antenna housing offers a favorable price-to-functionality ratio while maintaining the manufacturer's original specifications. Such components are popular choices for body repairs when the priority is compliance with the factory design and cost reduction compared to new components. Original origin ensures proper fitment with the roof and durability of the mounting.
