VSAT DSi6 (60 cm)


Compact and light-weight marine satellite internet antenna

The EPAK DSi6 is a stabilized marine satellite internet antenna designed for operation at sea; this small system can provide fast internet to offshore platforms, inland waterway boats, workboats, yachts and any other kind of marine vessel. This VSAT antenna combines the advantage of small weight and dimensions with an astonishing tracking speed and reliability of the Ku-band for an always-on internet experience.
