Satellite Radio In Trucks

Does anyone know if I were to buy a dash mount dock with satellite receiver for sirius xm would i have to have an outside antenna mounted on the truck?

Yes you would

Check out the radio already in your truck. It just may be Sirius compatible already. Just saved you some buck$.

I have my antenna inside, up high in the sleeper. It works fine

I ran the antenna on my dash, worked fine would cut off some, I've seen folks run the line thru the cab and engine out to one of the hood mirrors, saved the some $ :) I like the idea of running it high in the sleeper next to the Qualcomm reciever, on the Cascadia I'm in its on the passenger side top of the cabinet in a little cubby hole. Seems to get good reception

I ran my small cable under the passenger seat, notched out the sill plate front and back, running the cable through there. I then ran it up along the inside of my door seal. It tucks effortlessly in that location. I ran it to the top and between the door and window pillar. It doesn't contact metal anywhere or pinch. The antenna rests on the visor on top near where it curves. works perfectly
