Introduction

If you are having issues with reception or choppy audio with your radio, you should always start by checking your radio antenna, since it is the most common point of failure for the radio.

The radio antenna is the link between your stereo and radio waves on the air. If it is damaged or dirty, you may have issues receiving audio.

This guide will show you how to replace the radio antenna on a 2012 Mazda CX-7, but many cars have similar antennas to the one shown in this tutorial. Some steps on this guide may apply to other vehicles.
