Technical information
- Manufacturer: Stellantis (Citroën/Peugeot)

Function
The antenna provides radio reception for AM/FM bands and is the primary aerial for the vehicle’s radio system. The mast transmits collected signals down to the antenna base and coax cable into the head unit. Properly mounted and sealed, it maintains consistent reception and prevents water ingress at the roof feed-through.
Replacement And Fitting Instructions
Removal and installation are straightforward for experienced technicians and competent DIYers. Typical procedure:
- Park the vehicle on level ground and switch off the ignition.
- Carefully remove the interior roof lining or access trim to reach the antenna nut if required.
- Unscrew the antenna mast from the base (often by hand or with an appropriate socket) and disconnect the coax connector.
- Remove the antenna base fixing nut and lift the old unit away, taking care to preserve any sealing gasket.
- Clean the mounting area, fit the new seal/gasket, position the new antenna base, tighten to the manufacturer’s torque specification, reconnect the coax and fit the mast.
- Test radio reception and check for water tightness after installation. Refit interior trims.
Installation Recommendations
- Perform installation in a dry, sheltered environment to ensure correct sealing.
- Use the correct size tools and do not overtighten plastic components to avoid cracking the base.
- Inspect the coax connector for corrosion or damage and replace the cable if degraded to restore optimal reception.
- After fitting, verify reception across AM/FM bands and drive-test to confirm signal stability.
Why The Part Most Commonly Fails
Roof antenna masts typically fail due to mechanical damage (car washes, vandalism, impact) or progressive corrosion at the mast or connector. Water ingress from a damaged or aged gasket can lead to poor reception and, in some cases, electrical corrosion at the coax connector. Fatigue or loosening of the base fixing may also cause intermittent reception or rattling noises.
Durability And Maintenance
There is no fixed replacement interval—these parts commonly last many years under normal use. Inspect the mast and base periodically for physical damage, ensure the sealing gasket remains intact, and clean connectors if reception degrades. Prompt replacement after visible damage will prevent water leaks and preserve the vehicle’s interior and electronics.
