Purpose and compatibility

The "shark fin" antenna housing has been designed for BMW F-series models, such as the F20, F21, F31, and F34. The OEM construction ensures a proper fit to the roof contours and correct seating on the antenna base, which reduces the risk of leaks and unwanted vibrations while driving.

Thanks to the factory geometry, installation is predictable and repeatable, without the need for bodywork modifications. This is particularly important during post-accident repairs or when replacing a damaged housing after roof work, such as body and paint repairs.

Estoril Blue Metallic – B45 color

The finish in Estoril Blue Metallic – B45 is characteristic of dynamic BMW configurations, often found in sport-oriented versions. Using this housing allows you to:

• maintain color consistency between the roof and the rest of the body,
• minimize the need for additional painting if the car has the same paint code,
• preserve the original, factory character of the vehicle.

The metallic paint structure works well with the roof line, emphasizing the sleek shape of the "shark fin" antenna and improving the overall appearance of the vehicle.

Construction and function of the antenna housing

The housing from the Car Antennas category serves primarily a protective and aesthetic function. It shields the actual antenna module from atmospheric factors, such as water, UV radiation, or road debris, while simultaneously streamlining airflow over the roof.

The "shark fin" profile has been developed to reduce air turbulence and noise at higher speeds. A properly selected housing helps maintain the stability of the antenna, which is important for the quality of radio signal reception or communication systems, depending on the vehicle configuration.

Characteristics of the used component

As a used part, the antenna housing represents a reasonable compromise between repair costs and maintaining original BMW specifications. Such components are frequently chosen for repairs of several-year-old vehicles, where visual and structural fit is key, while also keeping the service budget under control.

A used OEM antenna housing is also a way to reduce the risks associated with non-original replacements, which may differ in shape, material quality, or the precision of the fit to the roof.

Why choose used original BMW parts

The market for premium brand parts is increasingly turning toward proven components from dismantling.
