Satellite TV provides an opportunity to view many Russian and foreign TV channels in high quality. The digital format, ahead of the usual analog broadcasting in all respects, guarantees excellent picture and sound. The basic set of satellite television consists of an antenna, a connecting cable, a converter and a receiver.
There are two types of satellite dishes: offset and direct focus. The antenna diameter, which can range from 60 centimeters to 3 meters, determines its capabilities, such as the quality of the received signal, the number of channels, and the ability to receive a signal from several satellites. A large-diameter antenna will need to be purchased for those who live in areas with poor satellite coverage, unable to provide a signal of the required power. The satellite dish should face south, so if your apartment windows face south, you can place the dish directly next to the window. Everyone else will have to place the antenna on the roof of the house. In addition, in the direction of reception of the signal, the antenna should not be interfered with by any obstacles such as tree branches.
The converter is a receiver that converts the satellite signal and transmits it to the receiver through a cable. The converter, which includes a highly stable local oscillator and a signal preamplifier, is installed on an external bracket focused by a satellite antenna. Receiver devices differ depending on the input frequency range, the type of polarization received, the number of outputs, and the noise figure.
The main functional component of a satellite TV set is a receiver - a device that decodes a satellite signal and transmits it to a television device for display. To watch free channels, the simplest inexpensive receiver will be enough. More expensive models with card readers and a hard disk are intended for viewing paid packages and recording the programs being viewed.
In addition to the above devices, you will need to purchase a connecting cable through which the satellite signal received by the antenna will be transmitted to the receiver. If the distance between the antenna and the tuner does not exceed 15 meters, any RG-6 cable will work for you.
