Shakespeare SRA-40 SiriusXM Marine Antenna

Shakespeare SRA-40 Marine SiriusXM Satellite Radio Antenna (SRA-40)

The Shakespeare SRA-40 is a compact, ultra-low-profile marine satellite radio antenna engineered to capture and amplify Sirius, XM, and SiriusXM network signals (2320.0–2345.0 MHz) on powerboats, yachts, and commercial vessels. Operating with a high-gain internal LNA (36 dB nominal), it delivers crystal-clear audio reception even in challenging offshore conditions.

Enclosed in a durable, white UV-stabilized ASA plastic housing, the SRA-40 resists yellowing, cracking, and saltwater degradation. The included pedestal mount adapter features standard 1"-14 threads for attaching to standard marine antenna ratchets, extension masts, or deck mounts, while also allowing direct low-profile surface mounting through surfaces up to 1 inch thick.

Key Features

• High-Gain Signal Amplification: 36 dB nominal LNA gain boosts satellite radio reception over long distances from land base stations and satellites.

• Ultra-Low Profile Form Factor: Compact 3.5-inch diameter footprint minimizes windage and prevents line snags on open decks.

• Versatile Dual-Mount Options: Mounts directly flush through bulkheads/cabin roofs or attaches via the included 1"-14 threaded pedestal base.

• No Ground Plane Required: Built-in ground plane independence allows mounting on fiberglass, composite, wood, or metal surfaces.

• 25ft Marine Coaxial Cable: Supplied with low-loss RG-58 cable with SMB and TNC connectors for plug-and-play attachment to SiriusXM receivers.
