Purpose and fitment

The "shark fin" housing has been designed specifically for selected Mercedes W212, W218, and W246 class models, ensuring it maintains the factory body lines and stylistic consistency. The component is mounted at the rear of the roof, which allows for optimal placement of the antenna installation and reduces the risk of mechanical damage during daily use.

The original design of the housing facilitates fitting to the factory mounting hole and seals, which helps maintain roof tightness and the proper operation of the electrical system responsible for signal reception.

Construction and technical function

The roof antenna housing serves a protective function for the antenna module, shielding it from atmospheric factors such as moisture, UV radiation, or road debris. The stable, refined geometry supports secure mounting on the rear of the roof, minimizing vibration and noise at higher speeds.

The "shark fin" profile was developed with the goal of maintaining favorable aerodynamic properties of the body. As a result, the element does not disrupt airflow, while simultaneously allowing for the aesthetic concealment of the antenna responsible for radio communication or other vehicle system functions.

Benefits of using an original housing

Using an original "shark fin" roof antenna housing allows you to:

• restore the consistent, factory look of the rear roof section,
• maintain the correct position and protection of the antenna module,
• reduce the risk of leaks at the mounting point,
• maintain stable operating conditions for the signal reception system.

For users who value original Mercedes solutions, this is a practical way to perform a technically correct repair after damage or wear of the previous housing, without the need to interfere with the roof structure.

Condition and service application

The item belongs to the Car Antennas category and is intended for service applications, such as replacing a damaged or leaking roof antenna housing. The used nature of the product makes it a cost-effective solution while maintaining the original geometry and fitment to the bodywork.

The housing will work well both for standard repairs after a collision or mechanical damage, as well as for restoring the completeness of the vehicle's equipment after previous modifications.
