Purpose and function of the roof antenna

The shark fin roof antenna is responsible for handling radio signals and onboard systems, depending on the specific vehicle configuration. Mounted centrally on the roof, it operates under optimal wave propagation conditions, which promotes stable reception. Using an original component allows for maintaining the factory geometry and the tightness of the connection with the roof panel.

Cosmos Black Metallic - 303 paint finish

The surface of the antenna is finished in Cosmos Black Metallic - 303, characteristic of many E-Class units. The metallic structure of the paint harmonizes well with the body lines, reducing the need for additional painting after installation, provided the car has the same color code. As a result, the element can be used both as a replacement part after damage and for visually retrofitting the roof with an original antenna module.

Installation characteristics

The "shark" type roof antenna is designed for the specific contours and mounting holes of the S212 roof, which facilitates proper seating and sealing. Using the original design allows for:

• maintaining the correct aerodynamic profile in the rear part of the roof,
• proper routing of cables inside the headliner,
• maintaining the tightness of the connection with the roof panel.

Thanks to this, after replacing the antenna, it is not necessary to make sheet metal modifications or interfere with the roof structure beyond standard disassembly and assembly.

Component condition and service application

The offered antenna comes from a used vehicle, which makes it an attractive alternative to new components for post-accident repairs or replacement after mechanical damage. This type of element is often used in:

• repairs after interference with the roof (e.g., after installing accessories or roof racks),
• restoring the original look after unsuccessful styling modifications,
• replacing missing elements after dismantling the antenna installation.

Integration with other Mercedes body components

If you are planning a comprehensive repair or modernization of the roof area in your Mercedes and need other elements from the same group, such as roof moldings, covers, or additional modules mounted in the roof area, check the available parts in the Other Mercedes category.
