Description
Antenna Impedance Module, Impedance Adapter for Peugeot 307 CC
This antenna impedance module (antenna adapter) is designed to restore correct signal matching between the vehicle antenna and the factory radio in Peugeot 307 CC models. The part is identified by OE codes 9652016980 and 6561R5 and is intended for technicians and DIY enthusiasts who need a reliable replacement to recover radio reception quality and prevent signal loss or interference. Replacing a faulty impedance module often brings back clear FM/AM reception and improves DAB/auxiliary antenna performance where applicable.
Technical Information
Manufacturer: Stellantis / Citroën / Peugeot
Model: Peugeot 307 CC
Product Codes: 9652016980, 6561R5
Additional Numbers: 9652016980 / 6561R5 (Reference OE Identifiers)
Function
The Antenna Impedance Module Matches the Impedance Between The Antenna And The Radio Head Unit. By Adapting Impedance It Reduces Signal Reflection, Optimizes Signal Transfer And Helps Maintain Stable Radio Reception. Without A Proper Impedance Match, Reception Can Be Weak, Distorted Or Intermittent.
Typical Failure Modes
Most Failures Result From Water Ingress, Corrosion On Connectors, Mechanical Damage To The Aerial Or Cable, Or Degradation Of Internal Electronic Components Over Time. Symptoms Include Poor Or No Reception, Intermittent Signal, Or Complete Loss Of AM/FM Reception Despite A Sound Head Unit.
Why The Part Most Commonly Fails
Exposure To Moisture And Road Salt Leads To Corroded Connectors And Oxidation Of Contacts. Repeated Movement Or Accidental Impact To The Antenna Mast Or Coaxial Cable Can Break Internal Connections. Thermal Cycling And Age May Also Cause Component Drift Or Failure In The Impedance Adapter.
Replacement Procedure
1. Prepare Work Area: Park On A Level Surface And Ensure Ignition Is Off.
2. Disconnect Battery: For Safety And To Prevent Short Circuits, Disconnect The Negative Battery Terminal Before Working On The Radio Or Antenna Wiring.
3. Access Module: Depending On Vehicle Specification The Impedance Module May Be Located Near The Antenna Base, Under Interior Trim Panels Or In The Boot Area. Remove Relevant Trim Panels Carefully Using Trim Tools To Avoid Damage.
4. Disconnect Connectors: Unplug Antenna Coaxial Connectors And Any Electrical Plugs Securing The Module.
5. Replace Module: Remove The Old Module, Fit The Replacement In The Same Orientation, Reconnect All Connectors Securely And Route Cables As Original.
6. Reassemble And Test: Refit Trim Panels, Reconnect The Battery, Start The Vehicle And Test Radio Reception Across Bands To Confirm Proper Operation.
Installation Recommendations
Use Dielectric Grease On Coaxial Connectors To Minimize Future Corrosion. Inspect The Antenna Mast And Coaxial Cable For Damage And Replace Any Worn Sections To Avoid Repeated Failures. Ensure Connectors Are Fully Seated And Secured With Original Clips Or Fasteners. If Reception Issues Persist After Replacement, Check Antenna Grounding And Continuity Of The Coaxial Cable.
Why Choose This Replacement
This module Is A Direct-Fit Solution For Peugeot 307 CC Vehicles Using OE Codes 9652016980 / 6561R5. For Mechanics And Enthusiasts Looking To Restore Factory Radio Performance Quickly, Fitting A Correct Antenna Impedance Module Is A High-Value Repair That Directly Addresses Signal Matching Problems.
