The main trends in the development of marine satellite dishes

The increase in the volume of data transmitted from ships to shore means for shipowners and managers the need to upgrade satellite communication antennas to more powerful ones. Today, VSAT marine antennas have low power supplies of about eight watts or less in order to maintain their low weight. This is enough to connect the VSAT equipment operating in the transmission mode of the standard downstream ship traffic, but not enough to increase the upstream traffic transmitted from the ship to the satellite.

In order to adapt the equipment to higher data rates on the uplink, antenna manufacturers can install high power supplies, which leads to an increase in the total weight and size of the antennas. However, Cobham Satcom has developed a 20-watt power supply with the same dimensions and weight as the 8-watt one. The device was included in the high-power version of the Cobham Satcom Sailor 900 VSAT equipment. Continue reading

What is an active antenna and passive antenna?

Thanks to the dynamic development of television broadcasting in the modern world, there is probably no person who does not encounter antennas. In order to watch their favorite TV shows in the best quality, the user needs to connect the antenna to his receiving equipment. And then the question arises: which antenna to choose, active or passive? In this article, we will consider in detail the features of each antenna, as well as the scope of their application. But first of all, it is necessary to give a detailed definition of the very term “antenna” and briefly describe the history of creation.

Heinrich HerzAntenna is a special device whose main task is to receive or emit radio waves. It converts the fluctuations of the electric current into a radio wave or vice versa. As can be seen from the definition, antennas can operate on reception, transmission, or transmission. The simplest antenna operation Continue reading

Famous Brand Satellite Television Equipment

Satellite TV is a high-tech service that offers the user a huge selection of television channels for every taste anywhere in the world. Satellite dishes mounted on the walls and roofs of houses have long been accompanying our lives, allowing you to watch satellite television at home. A dish connected to the receiver is installed stationary, is oriented to the satellite and works in one position for the entire service life.

Another thing is satellite TV equipment for mobile objects, for example, cars, buses, trains or ships. On a moving object, which is any vehicle, installing a satellite dish is useless, because without an accurate orientation to the satellite, the entire system is unsuitable for use and will be like a stopped clock showing the correct time only twice a day.
