Multiple mounting options available. The most common mount is the mirror mount designed just for your truck. Mounts now available for the all new P4 series 2018 - 2021+ model years that use the 3-bolt mirror arm design.
Spot mirror brackets are another location that provide an easy install path for your CB antenna, Cell Phone Antenna, or Sirius/XM Antenna.
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.
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.
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>
Attaches behind a spot mirror and provides you with a good mounting location for a satellite, cellphone, or CB antenna setup. Especially handy on vehicles with fiberglass bodies or mount locations lacking a ground plane.
Attaches to the spot mirror bolts and allows you to use a satellite radio antenna as well as a CB or AM/FM antenna on the same mount. Fits on any spot mirror attached to a vertical surface. Simply remove the mirror bolts, put the bracket in place, and reinstall the bolts.
