How is it used? The Universal Screw-in Aerial is used to capture AM and FM radio broadcast signals for a vehicle's audio system. It installs easily by unscrewing the existing aerial mast from the base on the car's roof or fender and then screwing the new universal aerial mast into place, using the correct thread adapter if necessary. Once installed, it allows the car radio to tune into and play AM/FM stations.

Compatibility: This aerial is designed as a "universal" replacement, meaning it aims to fit a wide variety of vehicles equipped with a screw-in type antenna base located on the roof or fender. Compatibility primarily depends on the screw thread size of the vehicle's existing antenna base. This product includes adapters for the most common M5 and M6 thread sizes, which cover a large percentage of vehicles found in New Zealand, including popular makes like Toyota, Ford, Holden, Mazda, Nissan, Mitsubishi, Hyundai, Kia, and Subaru.

However, "universal" does not guarantee a fit for every single vehicle model. Some vehicles may use unique or proprietary fittings, different thread types, or require powered/amplified antennas, which this passive mast cannot replace directly. It is highly recommended to check the thread size of your current antenna mast or base before ordering. Simply unscrew your existing mast (if possible) and compare the thread size. While unfamiliar with your specific vehicle or devices, we offer a 14-day 'trial and return for refund less shipping fee' service to enable testing in your environment with your equipment.
