Siren Marine SirenSat Offshore Satellite Antenna

The Siren Marine SirenSat Offshore Antenna extends compatible vessel monitoring beyond ordinary cellular coverage. It communicates using the Globalstar Simplex satellite data network. This makes it useful for tracking a boat in locations where a cellular connection is unavailable.

With an active SirenSat service, the antenna supports vessel location check-ins about every 15-30 minutes. A 2 m power harness is included for connection to a 12V supply. It is compatible with Siren MTC and Siren 3 Pro installations. Satellite communication is separate from the cellular connection used by standard nearshore monitoring. Geo-fencing adds another way to monitor an unattended vessel when paired with a compatible Siren system.

A separately purchased SirenSat Offshore subscription is required for satellite operation. This accessory is not a stand-alone vessel-monitoring system. Plan antenna placement, power routing, and service activation together before relying on offshore notifications. Find more power system monitoring & control for connected vessel systems.
