Satellite radio for your boat just got easier. And smaller! Specially designed for smaller boats that ply inland waters, SRA-25 Digital Satellite Radio Antenna sports an ultra-low-profile. Tiny as it is, it delivers plenty: weather, news, music, sports, and entertainment from Sirius Satellite Radio. The versatile SRA-25 accommodates a variety of mounting methods, with or without running its cable through the mounting surface.
