Where is the CB antenna on a 2019 Freightliner Cascadia 218? This is a common question among new Cascadia owners and drivers looking to install or replace their CB radio system. The good news is that this truck model comes with several factory-designed mounting locations that make installation relatively straightforward.
Common CB Antenna Mounting Locations
The Freightliner Cascadia 218 features several manufacturer-designed locations for mounting CB antennas:
- Mirror Bracket Mount: The most popular location is the driver’s side mirror bracket, which comes with pre-drilled holes specifically designed for antenna mounting.
- Roof Mount: The aluminum roof has designated areas for antenna installation, typically toward the front of the cab.
- Hood Mount: Some drivers prefer mounting CB antennas on the hood, though this is less common than the mirror or roof options.
For most professional drivers, the mirror bracket mount provides the best balance of signal quality and ease of installation.
Installing Your CB Antenna on the Mirror Bracket
If you decide to go with the mirror bracket mount, here’s a step-by-step guide to help you through the process:
Required Tools and Materials
- CB antenna kit compatible with your truck
- Coaxial cable (typically RG-58 A/U)
- Wrench set
- Socket set
- Electrical tape
- Cable ties
- SWR meter
Installation Process
- Locate the mounting point on the driver’s side mirror bracket. You’ll find pre-drilled holes designed specifically for antenna mounting.
- Attach the antenna mount to the mirror bracket using the hardware provided with your antenna kit. Make sure to tighten securely as vibration can loosen the connection over time.
- Run the coaxial cable from the mirror mount into the cab. The Cascadia typically has a rubber grommet or access point near the door hinge for routing cables.
- Connect the coaxial cable to your CB radio unit inside the cab.
- Tune the antenna using an SWR meter to ensure optimal performance.

Roof Mount Installation
If you prefer installing your CB antenna on the roof, here’s what you need to know:
- Identify the proper location – The aluminum roof has reinforced areas designed for antenna mounting, typically near the front of the cab.
- Use the right mounting hardware – Since the Cascadia has an aluminum cab, you’ll need to use appropriate hardware that won’t cause corrosion between dissimilar metals.
- Create a proper ground plane – The aluminum roof may require additional grounding measures for optimal CB performance.
- Weatherproof the installation – Make sure to properly seal any holes drilled in the roof to prevent water intrusion.

Optimizing CB Performance
Once you’ve installed your CB antenna, follow these tips to maximize performance:
SWR Tuning
The unique metal composition and shape of the Cascadia can affect CB signal performance. To optimize your setup:
- Check the SWR reading across all channels (1, 19, and 40) to ensure balanced performance.
- Adjust antenna length according to the readings – shorter for high SWR on channel 1, longer for high SWR on channel 40.
- Verify ground connection quality between your antenna mount and the truck’s body.
Common CB Antenna Issues
Cascadia drivers occasionally report these common issues:
- Interference from LED lights – The truck’s LED lighting system can sometimes cause radio interference. Installing ferrite cores on the coaxial cable can help reduce this issue.
- Mounting stability – Due to the aerodynamic design of the Cascadia, antennas can experience significant wind resistance. Make sure all mounting hardware is secure.
- Cable routing damage – Improper cable routing can lead to pinched or damaged coaxial cables. Use grommets and protective sleeves at potential wear points.

Recommended CB Antennas
Based on extensive testing with the Freightliner Cascadia, these CB antennas offer superior performance:
- Firestik FS-4 – The fiberglass construction stands up well to highway speeds.
- Wilson 5000 – Provides excellent range and clarity when mounted on the mirror bracket.
- Francis Antenna FT-18 – Specifically designed for modern trucks, with tuning characteristics that match the truck’s electrical system.

Legal Considerations
When installing a CB antenna, be aware of these legal requirements:
- Height restrictions – Some states limit the total height of vehicles and their attachments. The standard height plus a roof-mounted antenna may exceed these limits.
- FCC regulations – All CB radio operations must comply with FCC Part 95 regulations.
- DOT inspections – Improperly secured antennas could be flagged during DOT inspections.
