I received the answer below from XM Radio:
In most home applications in the US, the XM radio antenna will require placement in a window with a clear view of the Southern sky. The antenna features a weather-resitant design and can be mounted otdoors if that is the only way to obtain a clear Southern exposure.
Delphi is releasing a 50' antenna extension with improved design in an effort to mitigate any field issues that may arise from using the now out of stock design.
Approximate date of availability is the week of July 14th. And of course, we apologize for any inconvenience, but felt it important to release the new product without retired inventory remaining in the field. The new design should also address concerns about use in the boom box as well.
