Shakespeare Galaxy SiriusXM Satellite Antennas: Marine-Grade Reception on the Water

When it comes to bringing satellite radio aboard your vessel, few names carry more credibility than Shakespeare Antennas. Sirius/XM satellite antennas demand reliability in tough, moisture-laden environments — and Shakespeare's deep roots in marine antenna engineering make them a natural choice for boaters who refuse to sacrifice their entertainment or connectivity on the open water.

Shakespeare's Galaxy series is the cornerstone of their SiriusXM antenna lineup. Shakespeare has built the Galaxy brand into what many consider an industry benchmark, and that same commitment to quality carries directly into their satellite radio offerings. The Galaxy SRA-50 and SRA-25 are the two flagship models, each purpose-built for marine environments while also working well in RV and other outdoor applications.

The Galaxy SRA-50: Versatile Installation for Any Vessel

The Galaxy SRA-50 is Shakespeare's most feature-rich SiriusXM antenna. Designed especially for marine applications, it is a SiriusXM® approved accessory that meets or exceeds the most recent specifications set forth by SiriusXM®. The antenna features a sleek, white ASA plastic housing that keeps a remarkably low profile — just 2.25" in diameter and 0.75" high in flush-mount configuration. One of its standout practical features is its four distinct mounting options: flush, low-profile, pedestal, and attachment to standard mounts, giving installers maximum flexibility regardless of boat layout. The package includes a 25-foot low-loss coaxial cable terminated with a quick-disconnect, gold-plated TNC connector at the antenna base — details that reflect Shakespeare's long-standing attention to signal integrity and corrosion resistance.

The Galaxy SRA-25: Compact Flush-Mount Simplicity

For boaters prioritizing a minimal footprint, the Galaxy SRA-25 offers a compact flush-mount solution. At just 3/4" high, it nearly disappears on deck or cabin-top installations. Like the SRA-50, it ships with a 25-foot low-loss cable and TNC connector, and it can be mounted directly to a flat surface with or without cable pass-through access underneath — a practical advantage for retrofit installations. The SRA-25 is also well suited for RVs and other outdoor platforms where weather resistance and corrosion protection matter.

Why Shakespeare Excels in SiriusXM Antennas

Shakespeare Antennas brings over a century of engineering heritage to this product category. The brand has long been recognized for milestones like the development of low-angle radiation techniques, fiberglass radomes, and hand-soldered connections with brass and copper elements — innovations that signal a level of manufacturing rigor uncommon in consumer-grade antenna products. For Sirius/XM satellite antenna buyers, this translates into antennas that are not just electronically compliant with the SiriusXM network, but also physically built to endure salt air, UV exposure, and the vibration stresses of a working vessel. Both the SRA-50 and SRA-25 are compatible with all Sirius, XM, and SiriusXM radios and docks that use a push-on style SMB connector, ensuring broad compatibility across virtually any receiver setup.
