Is your Mercedes S320’s power antenna giving you trouble? Power antennas, while convenient, are prone to malfunctions over time. Many S320 owners opt to convert to a fixed antenna for a more reliable and often more aesthetically pleasing solution. This guide will walk you through the process, answering common questions and providing detailed instructions.
Understanding the Issue: Why Convert?
Power antennas on older Mercedes models, like the S320, are known to have a few common problems:
- Motor Failure: The antenna mast is raised and lowered by a motor that can wear out, leading to a stuck antenna.
- Bent Mast: Accidents or even automated car washes can bend the delicate antenna mast, hindering its operation.
- Electrical Issues: Wiring problems or a faulty antenna switch can also cause the power antenna to malfunction.

Identifying the Problem: Is Conversion Necessary?
Before converting, it’s helpful to try and diagnose the specific issue with your power antenna:
- Check the Fuse: Start with the basics. Locate the fuse for the power antenna in your S320’s fuse box and ensure it hasn’t blown.
- Listen Carefully: When activating the antenna, listen for any unusual sounds coming from the antenna motor. Grinding or clicking noises indicate a mechanical problem.
- Inspect the Mast: Visually inspect the antenna mast for any visible bends or damage.
If you’ve ruled out a simple fix like a blown fuse, converting to a fixed antenna might be the most cost-effective and reliable solution.
Gathering Your Supplies: What You’ll Need
Converting to a fixed antenna is a relatively straightforward process. Here are the tools and materials you’ll need:
- Fixed Antenna: Choose a fixed antenna that’s compatible with your Mercedes S320. Ensure it provides good reception and matches your car’s aesthetic.
- Tools: Basic hand tools like a socket set, wrench, and screwdriver should suffice.
- Electrical Tape: Used to insulate any exposed wires.
- Panel Removal Tool: (Optional) To help pry off interior trim panels without causing damage.
