Is this thing close to XM's bird? The reason I ask is because I had no problems listening to my XM at work. Always had a strong signal all day and night. It even worked when I closed my mini blind on my way out of my office. Now that I have Sirius. This thing only works minutes at a time and sometimes takes an hour to find a signal back. The window in my office faces north. I just have the antenna sitting on top if my computer tower that is level with the bottom of the window. There is a good clear view. I never had a signal problem with the XM antenna.
