This shark fin antenna is designed to fit over the existing antenna base using a high-strength 3M adhesive tape. It contains a copper signal wire and a micro-circuit that enhances radio signal clarity in weak areas. The sleek low-profile design reduces wind noise and improves the overall silhouette of the vehicle. Made from high-quality ABS plastic with a UV-resistant paint finish to match your car’s color. It is a simple plug-and-play upgrade that requires no drilling or wire cutting.
