Where to mount?

The Cascadia trucks usually come with a built-in RA-Miller antenna system that you can't see. In an effort to improve efficiency, Freightliner has moved the stock location for the antennas inside the cab. However, this causes massive performance issues. To get around this, use the CASP3 or CASP4 mount on the mirror, depending on your model year.

What type of antenna?

The lower mirror arm mounts work best with a top loaded fiberglass antenna, we suggest the 5 foot Firestik series or the 5 foot Thruster MAXX antennas for optimal performance. Alternatively, you can use your favorite bottom loaded antenna - Wilson 2000, Stryker SRA10, as long as you add a longer 22" Shaft or 36" shaft to your antenna.

Which radio should I use?

The older generation Freightliner Cascadia trucks have either an overhead compartment "cubby" system designed for Cobra 29 chassis radios, or an on-dash mount which doesn't limit the radio's size. The newer P4 generation has a larger cubby that can accept much larger radios. In either case the Stryker SR447HPC2 is an extremely popular, high powered 10 meter radio that would fit, or the Ranger RCI39VHP 90 Watt 10 Meter Radio is another popular option that will work no matter the year of your truck.,/p>
