Installation Recommendation

Intended for fitment by trained mechanics or experienced DIYers. Typical installation steps:

• Gather tools: adjustable wrench or suitable socket, trim removal tools, cleaning cloth, dielectric grease or anti-seize.
• Access the antenna base from inside the roof lining if required (some models allow external unscrewing of the mast). Remove any interior trim carefully to reach the mounting nut.
• Unscrew the old mast from the base or remove the securing nut underneath the roof liner. Inspect the base, cable connector and seal.
• Clean mating surfaces and cable contacts. Apply a small amount of dielectric grease to the connector to prevent corrosion.
• Fit new sealing washer or gasket if available, screw the new mast into the base or secure the base with the nut. Do not overtighten—ensure a firm, watertight fit.
• Reinstall interior trim, test radio reception and check for water ingress after a wash or rain.

Why The Part Commonly Fails

• Mechanical Damage: Mast frequently bent or broken by automated car washes, low garage entrances, branches or vandalism.
• Corrosion: Thread and connector corrosion from long-term exposure to moisture reduces electrical contact and makes removal difficult.
• Seal Degradation: Deteriorated rubber gasket allows water ingress, leading to connector corrosion and poor reception.
• Poor Contact: Loose or oxidised connector at the base causes intermittent or weak signal.

Notes: When replacing the antenna, always check the condition of the base, cable and sealing washer. Replacing the gasket when fitting a new mast prevents future water leaks. After installation verify radio reception across AM and FM bands and ensure the mount is secure to avoid vibration noise.
