Purpose and compatibility

The presented roof antenna is an original Mini component, dedicated to the Cooper One R55 and R56 series after the LCI modernization. The design is based on the factory mounting points in the roof, which allows for installation in place of a worn or damaged antenna without the need for bodywork or wiring modifications.

The precisely selected base geometry and body shape ensure proper adhesion to the roof panel, reducing the risk of leaks and unwanted vibrations at higher speeds.

Construction and function of the roof antenna

The Mini roof antenna acts as an external radio signal transducer, working in conjunction with the vehicle's factory audio system. The applied design:

• enables effective radio wave reception in the typical ranges used in automotive tuners,
• is optimized for operation in the Mini R55/R56 body,
• maintains the factory height and shape, which reduces aerodynamic noise.

Thanks to the preservation of the original form, the antenna does not disturb the characteristic silhouette of the Mini, and its installation does not negatively affect the functioning of other roof elements.

Condition and service application

The item comes from the category of used Mini parts, making it an attractive solution for accident repairs, replacing a damaged antenna, or restoring the car to factory condition after modifications. Choosing an original antenna from dismantling allows you to maintain compatibility with the vehicle's installation and avoid problems typical of universal replacements.

The antenna will work well both in workshops specializing in the Mini brand and in independent services that need a component matched to the factory wiring harness and mounting.

Benefits of installing an original Mini antenna

• Factory fit – compatibility with the roof structure and electrical installation of Cooper One R55/R56 LCI models.
• Stable radio signal reception – design engineered for the requirements of the Mini audio system.
• Visual consistency – maintaining the original look of the roof without stylistic compromises.
• Service solution – beneficial for accident repairs and restoring the car to OEM specifications.
