Nowadays efficient work on the Internet is no longer conceivable without high-speed communication channels. For many users, however, and especially for those connecting to the Internet via ordinary telephone lines such channels still remain a dream. Nevertheless, a relatively simple and rather cheap possibility to furnish oneself with a wideband access exists there. Considering the present-day prices for equipment and services the technology of satellite-based access to the Internet is in the strongest demand on the market. To make such a wideband access to Internet attainable several satellite systems are employed at present.
Satellite antennas enable not only quick files downloads from the Net; they also open access to numerous television and radio channels as well as to various media services engaged in transmission of multimedia data from information-, business- and entertainment-related channels.
Function
The antenna configuration is made of wire in central parabola shape. It is painted with anticorrosion powder paint. It provides access to satellite TV signals. The antenna is to be installed on industrial and house buildings.
