- Ensure the connector is tight and free of corrosion; clean if necessary with electrical contact cleaner.

4. Test Antenna and Wiring

Tools Required: Multimeter
- Set the multimeter to continuity mode.
- Disconnect the antenna from the radio and test the continuity of the antenna cable from the antenna base to the radio.
- Check for any breaks or shorts in the wiring.

5. Replace Components (if necessary)

If any component is found damaged or defective:
- Replace the antenna with a compatible part.
- Repair or replace damaged wiring using solder and heat-shrink tubing or appropriate connectors.
