The MobileSpec Universal Satellite Radio Antenna (MSTRSAT) works with all satellite radio services (including SiriusXM, Sirius, and XM). This is for satellite radio reception use only and will not work with the Inmarsat IsatPhone 2 sadly, Mario.

I'm a truck driver and I need to know if this will work on a dash mounted Sirius XM car stereo? I am tired of the portable ones always have trouble with them and I'm getting a stereo
