Sirius XM Antenna

depending on time of day,the satellite is in different positions as it rotates in orbit with the earth.

i have the antenna on the cab visor of my semi truck,certain times of day(usually very early am and very early pm) i get intermittent reception depending on the direction of travel,this is because the cab visor is lower than the roof line and trailer roof line.they end up blocking the signal when the satellite is closer to the horizon and not high in the sky

the best location for the antenna is any where it has clear view of the sky

when we had a portable receiver we used a magnetic hockey puck style antenna that we placed on top of our CD-changer which was mounted in an overhead cabinet in front of and above the driver's seat. we would occasionally lose the signal going thru mountain passes but otherwise it worked fine.

Sirius XM's two satellites are in geosynchronous orbit. They are always in the same position in the sky.

I have trouble going south...or is it east,....or maybe west. In short, xm has crappy reception in all directions, especially in mountains where there are any trees. It is almost worthless here in most of Oregon. If you think it should work as good as GPS, you right, but it don't, and never will.
I paid for a 1 yr subsciption, and shouldn't have. It really is crappy reception. Never again

I have my portable unit antenna just laying on the dash. Driving North, I get interruptions occasionally. I also get interruptions if driving thru a tree-lined area where the trees are on the south side of the road.

mag mount on roof... 2 sided tape if needed... cord thru the door jam...

you can get extra mag mount type on e-bay.. even extra long cord.

I put my antenna on the metal bar where the old tv was- it works fantastic. In our class A the tv was mounted in an overhead cabinet between the driver and passenger seats. Apparently it transmits right through the fiberglass roof.

I used to use XM a lot. I rode a Goldwing and had the XM docking moduale mounted on the Wing. Worked great until I hit the north side of a tree or mountain.
I continued to use it after we sold the Wing and got into RV'ing. I used to just throw the antenea on the dash. Always worked well. I have several docking pods. I had one mounted in the trailer so I could use the same XM radio between them. I also had the Boombox too. It worked great around the camp spot.
Now we just use Pandora and a JBL flip. It's cheaper and has a way better music variety IMO.
It doesn't cut out unless I don't have a Verizon signal. 95%+ of the time I have music.
Not sure if your're tied into XM or what you have for a smartphone but Pandora is way better.

I was just about to say the same.

i had the same problem when placing the antenna on the dash. Had XM on the way to Florida but not headed back. Finally mounted it on the roof air horn. That was the only thing on my roof that was magnetic. Taped it down to the horn and have to retape about ever 3 months.
