Recommended for yachts from 35 meters to 45 meters.

The MST 105 HT4 WW is a worldwide antenna with double LNB for linear and circular polarization. With a radome of 129 cm in diameter and a parabola of 105 cm with a 3-axis stabilization system, it guarantees viewing of the channels in HD and ensures signal reception even with very rough seas and adverse weather conditions.

It allows the reception of satellite TV and, with the special kit, it also allows the reception of meteosat live.

Main features :

  • The antenna with the simplest operating system in the world, without dozens of boxes and antenna connectors;
  • Italian manufacture: elegant, efficient, compact and light;
  • KU band with linear or circular polarization;
  • Interfacing with the on-board gyro is not essential;
  • “Compass Gyro Controlled” in the radome;
  • GPS “on board”;
  • Automatic polarizer;
  • Gyroscopes on three axes;
  • Three-axis inclinometers;
  • Non-magnetic kit against interference;
  • Navilink technology: a single cable between the antenna and the Control Unit;
  • Naviber technology to identify the chosen satellite;
  • Remote assistance for firmware updates and technical support;
  • 3-year warranty and worldwide service centers.

Wi-Fi kit

With this kit you can control all the tracking functions and change satellites, not only from the control unit, but also from your Smartphone or Tablet, at any time.

The Wi-Fi Kit includes: Sat 105 Wi-Fi control unit and Navisystem App for Smartphones and Tablets.

Switching kit

When there may be problems with obstacles between antenna and satellite, the kit for switching between two antennas ensures an uninterrupted vision, even if you want to receive two different satellites at the same time. The exchange between one antenna and the other takes place automatically as soon as one of the two loses the signal, but it is also possible to set the exchange in manual or priority mode in cases where you prefer.

Meteosat kit

The Meteosat kit allows you to receive live weather from the satellite to always be updated on the weather conditions.
