Quick And Easy

The Sailor 800 VSAT can be used on vessels that otherwise would not consider VSAT because of the size and weight of suitable antennas.

A Top Performer

The focus of the new SAILOR 800 VSAT is on RF performance, G/T, which is >18 dB/K - a value equal to or higher than most other 1m maritime VSAT antennae performance claims - yet it's much smaller and lighter. This performance makes the new 83cm antenna suitable for vessels that would normally specify a 1m antenna. The unique, class-leading performance of SAILOR 800 VSAT also opens up a world of high quality, reliable communications for a wider number of vessels including workboats, fishing vessels, inland waterways and yachts, whilst providing installation flexibility for vessels of all types and size.

Tried And Tested

If you know SAILOR 900 VSAT, you already know SAILOR 800 VSAT. It uses the same tried & tested features including antenna controller, software, electronics, web MMI, modem and network compatibility to provide reliability and stunning performance.

Lower Cost And Increased Up Time

The new SAILOR 800 leaves the factory fully tested and configured, with all RF equipment pre-configured and installed. This reduces the time needed on board for installation, resulting in lower start-up costs for users, whilst the SAILOR build quality ensures reliability and increased up time.

Smaller Form Factor

Customers who would previously have specified a 1m antenna or who may have considered VSAT too 'big' for their vessel, can now install a SAILOR 800 VSAT and enjoy the benefits of a 20% smaller form factor with the performance of a much larger antenna.

Two Antennas - One Modem

The SAILOR VSAT range enables you to operate two antenna systems on a single modem without the need for extra hardware to manage the feature; the integrated SAILOR VSAT antenna controllers manage the connection between satellite and modem. This simple dual antenna configuration ensures your vessel has a satellite connection even when there are obstructions in the way.
