Purpose and BMW fitment

The shark fin roof antenna housing has been designed specifically for BMW models from the F-family, where the antenna is located in the rear part of the roof. The housing design is adapted to the factory shape of the antenna base, which facilitates installation and allows for maintaining the body line consistent with the manufacturer's design.

The item belongs to the Car Antennas group, making it compatible with standard antenna installations used in these models. The housing serves a protective function for the antenna module and contributes to proper signal routing, reducing the risk of mechanical damage and the negative impact of weather conditions.

Color and body aesthetics

The finish in Midnight Blue Metallic - B38 allows for a consistent match to the body paint in the same color, without the need for additional painting. This is particularly important during post-accident repairs or when replacing worn components, where maintaining a uniform paint surface is essential.

Thanks to the factory shade, the housing integrates well with the roof line without introducing accidental contrasts. Replacing a damaged housing with this component helps restore the aesthetics of the rear part of the vehicle and maintain the characteristic, dynamic "shark fin" profile typical of modern BMW models.

Protective function and rear vehicle mounting

The placement of the antenna in the rear roof zone requires a housing resistant to wind, precipitation, and temperature changes. The applied construction ensures a stable fit on the antenna base, which reduces the risk of looseness and unwanted vibrations when driving at higher speeds.

The housing is prepared for mounting in the rear position, in accordance with the factory body layout. With proper installation, the seal of the connection with the roof is maintained, which helps protect the vehicle interior and the antenna module itself from moisture and contaminants.

Characteristics of the used component

The presented antenna housing belongs to the group of used parts, which allows for an economical replacement of the element while maintaining the original manufacturer's specifications. Such components are often chosen for maintenance repairs when the priority is compliance with factory geometry and color, rather than purchasing a new sub-assembly.

Using an original, used housing from the same model series reduces the risk of fitment issues and eliminates the need for modifications to the roof or antenna base. It is a practical solution for users who want to restore the correct appearance and function of the antenna at reasonable costs.
