Dual VSAT Antenna Switch

Acutec Dual Antenna Switch

A marine VSAT antenna requires an uninterrupted view of the satellite, known as line-of-sight. If any piece of superstructure, rigging or another antenna enters the line-of-sight as the ship turns, communications can be impaired or interrupted.

Acutec Dual Antenna Switch (DAS) allows a second terminal to be installed to cover any blind-spots of the first. Together, the two VSAT antennas with the DAS provide full-sky coverage. This facilitates uninterrupted connectivity on vessels where line-of-sight cannot be guaranteed with a single VSAT antenna.

Unlike other switches, the DAS senses modem signal-strength when determining the best antenna to select. This makes it ideal for vessels where blockage changes over time for example offshore construction vessels with cranes and other moveable structure. A unique alogrithm examines inputs from the Sea Tel antenna controller and from the connected satellite modems. All radio communications are automatically routed through the un-blocked and best-performing antenna. Switching happens instantaneously, so that users are unaware of the changeover.
