Description
Antenna for Citroën C4 II B7 and DS4. Includes antenna mast.
This roof-mounted antenna assembly is a practical replacement part for Citroën C4 II (B7) and DS4 models. Supplied with the antenna mast, it restores reliable radio reception and maintains the vehicle’s exterior appearance. The part is commonly searched by its product numbers, making it easy to locate in parts catalogs or online searches.
How It Works
The antenna assembly receives AM/FM radio signals and, depending on the vehicle’s equipment, can be part of combined systems that support additional services. The mast and base transfer RF signals via a coaxial cable to the car radio. Proper mechanical and electrical connection is essential for good reception.
Technical Information
- Manufacturer: Stellantis (Citroën/Peugeot)
- Model: Citroën C4 II (B7), DS4
- Product Codes: 9665363880, 658770
- Other Numbers: 658772, 6561A0
Installation Recommendations
- Inspect the new part visually before fitment and compare with the removed unit to ensure correct version.
- Remove The Old Mast: Many mast types unscrew by hand. If the base must be replaced, remove the interior trim/headliner section to access the securing nut and coax connector.
- Disconnect And Reconnect The Coax Carefully: Avoid kinking the cable; ensure a clean contact at the connector to prevent signal loss.
- Sealing: Check And Replace Any Gaskets Or Seals To Prevent Water Ingress Around The Base.
- Tightening: Secure The Base And Mast Firmly But Do Not Over-Torque To Avoid Damaging Threads Or The Roof Surface.
- Check Reception: After Installation, Test Radio Reception Across Bands And Inspect For Intermittent Signal Caused By Loose Connections.
- Tools: Basic hand tools and trim removal tools are usually sufficient. For base replacements access from interior is typically required.
Reason For Failure
- Mechanical Damage: Breakage Of The Mast Due To Car Washes, Falling Debris, Ice, Or Vandalism/Theft.
- Corrosion And Water Ingress: Moisture Penetration At The Base Can Corrode The Coax Connector Or Cause Poor Grounding, Leading To Weak Or Intermittent Reception.
- Cable Wear Or Connector Failure: Flexing And Age Can Degrade The Coaxial Cable Or Its Connector, Resulting In Signal Loss.
- Poor Sealing After Previous Repairs: Improper Resealing Allows Water Entry And Accelerates Electrical Failures.
Practical Tips For Mechanics And DIY
- When Replacing The Antenna, Inspect The Coax Cable Continuity With A Multimeter To Confirm Signal Path.
- Clean Contact Surfaces And Use Dielectric Grease On Exposed Connectors To Reduce Corrosion.
- Keep The Old Unit Until Final Verification Of Reception; This Helps Troubleshoot If Reception Issues Persist.
- Search By Product Number (9665363880, 658770, 658772, 6561A0) For Fast Identification And Compatibility Checks.
