Siren Marine GPS, Cellular & WiFi Antennas

Siren Marine Antennas: Keeping Your Connected Boat® Online

Siren Marine has built its reputation around one powerful idea: your boat should be as connected as your smartphone. Central to that vision are the brand’s purpose-engineered GPS, Cellular & WiFi antennas — components that serve as the critical communication link between your vessel and the Siren Connected Boat® system. Whether your boat is docked, moored offshore, or sitting in a storage yard, these antennas ensure your monitoring data flows reliably to the Siren app in your pocket.

Combination Antennas: Two Functions, One Clean Install

Siren Marine’s standout antenna offering for the Siren 3 Pro platform is the Remote Cellular & GPS Combination Antenna — available in two mounting styles to suit different vessel layouts. The Remote GPS and Cell Antenna Adhesive-Mount Puck is easy to mount and will extend the GPS and cellular range capabilities of your Connected Boat System, strengthening the connection to your boat. For boaters who prefer a more traditional marine hardware look, the Remote GPS & Cell Antenna Threaded-Mount Dome extends the tracking capabilities of your Connected Boat® system, extending GPS and cellular range for the ultimate peace of mind.

Both combo antennas feature a 9.8 ft (3 m) cable length , giving installers enough reach to position the antenna in an optimal location — away from obstructions, fiberglass hulls, or electronics that may interfere with signal acquisition. The dome version measures 2 x 1.9 in (50 x 48 mm) and is compatible with the Siren 3 Pro only.

External GPS Antenna: Maximum Location Precision

For boaters who want to prioritize GPS accuracy above all else, Siren Marine also offers a dedicated External GPS Antenna. Designed to optimize GPS tracking of your boat, when remotely mounted, the External GPS Antenna causes the Siren 3 Pro to override the use of the internal GPS antenna — giving the system the best possible sky view for precise, real-time position data.

Going Beyond Cellular: The SirenSat Offshore Antenna

For vessels that venture beyond reliable cellular coverage, Siren Marine takes connectivity a step further. The SirenSat Offshore Antenna allows users to track their boat even after it leaves cellular coverage — a perfect solution for boat owners who keep their boats in theft-prone areas. It satisfies most insurance requirements for boats with multiple outboard engines, checks in every 15–30 minutes, and features geo-fencing capability with global coverage, non-dependent on cellular connection.

Built for the Siren 3 Pro Ecosystem

The Siren 3 Pro is the most advanced main device Siren Marine offers. Together with the Siren Marine Mobile App, the Smart Boat Monitoring System puts your boat in the palm of your hand 24/7, allowing you to monitor battery levels, bilge pump activity, water levels, shore power status, engine performance, temperature, location, and more. Advanced features include Global LTE (4G/5G), built-in NMEA 2000 connectivity, satellite readiness, and digital switching integration. The antenna lineup is engineered specifically to amplify and extend these capabilities — so whether you’re upgrading signal strength in a dense marina or tracking a vessel far offshore, there’s a Siren Marine antenna solution designed for the job.
