Sirius XM radio packaged as CB form?

I am guessing that you want to put an XM/Sirius head unit(tuner) above you instead of using the XM that is already built into your instrument panel AM/FM/XM exisiting radio.
You can put the XM tuner anywhere, it needs it's own special antenna and wiring, a CB antenna will not work. You need 12V power to it, and I would suggest the direct wired coax adapter that puts the output from the XM tuner directly into the AM/FM antenna input on your existing radio.
Running all of that from above your head down to instrument panel and hiding the wires will take some doing but not impossible. Depends on how clean you want the installation to look .

It's not built to be there. The cb antenna system is totally incompatible with xm radio.

I'd suggest using it for a cb/weather radio as it's designed.

We need better communication on the roads other than the middle finger. Hahahahaha

 

That allows you to extend the cable, does not allow use of the CB radio antenna. The XM/Sirius antenna has more than sufficient wire included to make it from the ideal mounting spot, which by the way is on the roof of the tractor, not on the mirrors. Mirror mounts will work, but not as well as a roof mount. Take a look at all the OEM antenna installations on new cars. All in the center of the roof.

 

i went thru this exact situation. and was going to run dual sat antenna until i found this out. first off what year is your truck because if its new enough (mines 2011 670) it will have built in sat radio antennas. the 2 antenna that are on the mirrors are mulit antenna and are cb/tv/sat radio. somewhere behind the dash radio area you will find a yellow square plug that looks like the pic below. that is the sat radio antenna plug. if you have an aftermarket deck that is sat ready you can get the sxv200 vehicle tuner or if you have an external sat radio then this yellow plug will plug into either BUT you will need this Sirius XM Radio FAKRA Antenna Adapter Connector Sirius XM Radio Factory Antenna Adapter: Amazon.ca: Electronics i found the signal way better with the 2 mirror antenna than just the one sat radio antenna. if you wanted to mount the sat radio up top in the cb area then you have to get the sat radio antenna wire extension to run from the yellow plug, up hte a pillar and across to the cb area, then run the audio out back down the deck and plug it into the aux on the radio. alot of work. personally id get a aftermarket deck and sat radio tuner. makes for a much cleaner install. if you have any questions just ask me.

 

the cb antenna are also the sat radio antennas.

 

The duplexer box is a half A approach Volvo used to match a antenna that is not actually resonant on most of the bands it operates.
