The Sternula Above Deck Unit is a maritime connectivity device in a protective casing, fit for the harsh maritime environment, that can be fitted on the vessel’s railing. The internal placement of the two diversity antennas ensures high environmental protection and robustness with good performance.

The unit has a lever in each corner of the box that fixes the lid to the casting thereby sealing and protecting the unit. Recognizing that water will condense on the inside of the box, due to fluctuating temperatures, the box has a flexible tube attached at the bottom that allows any water to escape the enclosure.

The main task of the Sternula Above Deck Unit is to provide mobile network data connectivity for ships in near-shore waters.
