Receives and amplifies the satellite signal. At a tiny 3.5-inch diameter, it’s ideal for smaller vessels. The low profile, white plastic housing mounts in a variety of ways with or without the included pedestal mount (pictured). When mounted directly to the surface, the antenna accommodates surfaces up to 1 inch thick. Even the included 25-foot cable is designed especially for marine use. Connects to any Sirius Satellite Radio receiver (works with both Sirius and XM satellite radio).
