If you mean the home antenna, make sure you got the clear angle for the signal. Or if you are in a relatively populous, urban area, there might be land based repeaters and you would be good. I bought the home antenna and I can't get a steady signal. Not that the $35 is all that much but I sure was disappointed. The ambitious person could pull the antennae out of the car and give that a shot to check for signal when near the house. Good luck with the antenna.
Also could try to sign up for the Internet account. I had that working a few times. Got a nice Ratdog show a couple years back but I butchered a few songs by fumbling with my deck. My wife is still unhappy with me. Seems every time I use the Internet account for Sirius, it is disabled the next time I try. They tell me it is included in the subscription and support usually gets it set up again. Always with a different username/password
Best of luck getting shows whatever you do.
