This is a SiriusXM satellite radio antenna. It operates on the XM network and should be compatible with any XM or SiriusXM satellite tuner that requires the antenna connector pictured. (Your plug has to be about 1/8", made of metal, with a plastic lining inside and a small pin in the center.) That is just about everything from the last couple years that has a SirusXM or XM logo. It will not work on tuners with the Sirius logo only because those use a different network.

It has a magnetic base. It was designed to be mounted on a vehicle. If you're wanting to use it indoors you should check to make sure others have done this. However, we do not guarantee it for indoor use, even if others say it works fine.

It has been unwound but has not been used on a vehicle. Since it is obvious it has been unwound, it cannot be sold as new. Our loss is your gain.

This is a clearance item. Returns are not accepted for any reason other than functional defect. Even then, your only option will be an exchange for the exact same thing.
