Just curious how they wire the antenna cables in these trucks. Im currently in an '06 Century and cant figure out if both antenna mounts on the mirrors are both used for the CB. The reason for asking is some CB shop guy I talked to said that some trucks use the right-side antenna as the AM/FM radio antenna and the left side is for the CB. Well, my truck has its own dedicated antenna for the stereo on the driverside where the stacks would be if it had them. I figure in this case that both mirror-antenna mounts are for the CB since I am only using the right side for my CB. Reason being, I was having really bad results with my CB and found out that a possible reason was because the driver-side antenna mount was missing the little nylon washer that goes between the mount and the place on the mirror where it mounts to. I decided to unhook the coax underneath the bottom mirror mount and only use the right side. It seems to work a little better, but its still kinda poor. I thought about getting a sheap SWR meter and some aftermarket cable and antenna mount for better results but since Im getting a new truck, I figured why bother.
As for the Cascadia I might be getting, Ive noticed that the only antennas Ive seen are the two on the sides of the sleeper. Are these the ones that CB shop guy told me that the driver side is for the CB and the other for the stereo?

Where else can you put an antenna on a Cascadia since the mirrors dont really have a place to mount them to?
-
On the Cascadia there is a rail for supporting the airlines on the rear of the cab, this is where the guys in our company mount antennas. We pull tankers that are not high like a box, but I don't know of a lot of options. -
Now alot of newer trucks use what they call a multiplexer box. Both antennas serve as Cb antennas along with being AM/FM antennas. You have to have matching antennas on both sides for it to work properly. It does not matter what antenna you use with these multiplexer type systems. The AM/FM radio could careless what you are using for an antenna.
I don't care for the sleeper mounted setups on some of these trucks. The antenna mounts are so low on the sleeper that very little of the antenna is above the roof line and the antenna is so close to the side of the truck that you get a huge amount of reflect which messes with the SWR and performance of the radio. You can't hardly put a longer antenna on them to get the majority of the antenna above the roof line without fear of taking out low flying aircraft. -
I drive an 07 freightliner Columbia. The driver side cb antenna is snapped off , I have the passenger side stock one still on. I was wondering if I needed to use the same style antenna on the drivers side or if I could repair that one with a 3k watt coil antenna? Any help our advice would be great. Thank you in advance.

Go with 2 Francis or tunable tip Wilsons.....They are not that expensive.
No need for those 3000 watt antennas.......those are the oil filled ones? Not needed and a poor antenna.
Myself i would run my own coax to one mirror and use a Wilson 2000. Easy to tune and will work way better than the co-phased factory crap. -

The company I work for has Cascadias, both sleeper and daycabs and I slipseat. I mounted my antenna on the air hose hanger bar for awhile, it worked ok but there was signal loss behind the trailer(dry box). I got to thinking there has to be a better way. I made a bracket and bolted 1/2 of a mirror mount with antenna onto it and mounted this onto the passenger door where that worthless mirror is supposed to go. tuned the antenna to 1.2 1.1 and 1.6. gets out and receives better than where it was. I run the coax down the door rubber and through the grommet on the lower right of the firewall. Then it comes up between the dash and door frame to the radio. My antenna is a k40 trucker.

If wanting to stay with fiberglass then these work well.
