Wilson Antenna 305518 Overview
Heavy duty all aluminum CB antenna mount for the newer 2018+ Freghtliner Cascadia P4 series trucks. Unsure if this mount will work? Look at your mirror arm, if there are 3 bolts that hold your mirror onto your door - this is the CORRECT mount. If your truck is 2017 or older and uses FOUR bolts, use the CASP3 P3 Mount instead.
