I purchased a SiriusXM vehicle tuner for my Class A. I was able to connect the tuner to my in-dash radio with no problem, however, I am having a problem installing my antenna. They suggest mounting it on the roof and running the wire down the walls and under the dash to the radio. I really don't want to put a hole in my roof. Has anyone installed one of these in your Class A, and if so, where did you mount the antenna? Can I mount it on the windshield inside and still get good reception?Rich

You should be good as long as the disc (antenna) is facing up toward the sky.I have one in my house and it gets pretty good , but not perfect, reception through my roof

The radio shop that mounted my XM ran the wire out through a marker light along the front roof-line. It was easily (for some people) accessible through the front TV cabinet. The wire is exposed for about 8 inches above the top light and the antenna is fixed to the roof with silicon adhesive. It has worked well for 6 years.With the silver full-body-paint the black wire is not noticeable. The wire could be tinted to match the RV.

I put the antennae for my XM radio on the roof of my 5'er. I ran the cable under the 5'er then up the rear outside corner molding. It's the molding that has the plastic insert that covers the screws. I then applied a big puddle of Dicor and set the antennae in it. Been there for a couple months and no probs. I had to buy a 25' XM extension cable to do it.

My antenna sits on my dash. And I don't have problems.

You will likely do ok if you have a southern facing campsite with it in your window. If not, you might struggle. If it were me, I'd try to mount close to a radio antenna or TV/Sat antenna use the same hole since your likely going to the same place. Remove the dicor around it, run your wire, tape up with eternabond and then cover with dicor self leveling. Screw the antenna through the roof into a truss and cover the same way. Eternabond covered with dicor seems to be pretty much leak proof from everything I have read about re-roofing or adding/replacing anything on a roof.

Update: To my surprise, I located an antenna already installed in the motor home above the cab. It was well hidden. I located the connector on the end of the cord under the dash and connected it to my tuner. Works great. No drilling. No cutting. Only hard part was locating the connector under the dash. It, too, was well hidden. Activated my SiriusXM and I ready for the road.

Is that the prewired CB antenna? I just ordered my XM radio should get it next week. If the CB antenna works I,ll use the one on my rig since I don,t have a CB.
