Based on the popular 4003 antenna, the new system makes further improvements including higher efficiency and increased operating ranges.
When a ship at-sea needs broadband internet or maritime VSAT, it needs an antenna that can point accurately in all sea states.
To avoid interference from signals meant for nearby satellites, communications regulators impose strict limits on antenna performance and beam widths.
For smaller antennas compliance can be difficult, so that previously, only larger systems on bigger vessels have had access to marine broadband speeds at sea. The 4006s remarkable performance changes that.
With a generous -20° to +115° range of elevation, the antenna is able to track low and high elevation satellites even when rolling and pitching. This effectively increases the useable coverage area for marine mobile VSAT, especially useful in areas such as Asia Pacific.
In addition, the new system uses an improved and highly efficient satellite dish and feed arrangement (>70%). All of these factors can equate to lower air-time costs, higher speed and fewer errors.
Sea Tel offers a range of maritime VSAT broadband internet and private network antennas, sized from 1m all the way up to systems with 3.7m diameter reflectors.
Acutec is an Australian company specialising in the application of marine satellite technology and works closely with Sea Tel.
With 28 years in the business and more than 20,000 systems installed on ships and yachts worldwide, Sea Tel is the worlds leading manufacturer of marine satellite TV and communications antennas.
