To install a satellite dish without involving specialists from the outside is quite feasible, but you need to figure something out. It should be understood that the satellite antenna receives television signals that "pass" the following way( in rough approximation): the transmitting antenna of the telecentre-the satellite in orbit-is our receiving satellite dish. In this case, we will make a reservation that the conversation will be about the independent installation of the simplest, and, perhaps, the most common antenna - an offset non-rotating "plate".That is, the antenna, the mirror of which is fixed and does not rotate. Such antennas are supplied by "Tricolor TV" and "Telecard", and many others.
Antenna installation site and mounting
The orbits of all satellites pass above the equator, so that they will be in the south direction( from South to South) to the territory of our country( and we are in the northern hemisphere, as we know).Therefore, the antenna should be directed precisely there. On the Internet there are articles that say that if the windows of the house are located in the direction to the south, then the antenna can be put in the apartment.
This is wrong. We will not pay attention to the dimensions of the antenna. There are apartments, as several antennas will fit, here it is in another. A high-frequency range is used to transmit satellite signals. For example, even the usual window glass "extinguishes" several times. And if there are plastic windows with double-glazed windows? What is the high quality of the image you can talk about?
installation principle
Therefore, to install the antenna yourself, you need to correctly determine the location. It can be a house wall, a roof, a specially prepared, rigidly fixed mast. Can be installed on the balcony. The main thing is that there are no visible obstacles to the passage of the signal from the satellite( high-rise buildings, for example).It is necessary to fix the antenna so that it does not "walk" with strong gusts of wind, otherwise there will be systematic distortions of sound and images. Usually the antenna is attached to metal brackets.
It is necessary to foresee the necessity of some adjustment of the antenna( for better signal reception) during operation. Therefore, the place chosen for antenna mounting should provide not only convenience of approach to the mirror, but also the possibility of setting up works. Be sure to support the antenna( or brackets) so that it occupies a strictly vertical position, so use a level that is better than laser. This is due to the requirements for fine tuning to receive signals. The converter feeder should be placed in the focus of the antenna, accuracy is also important here.
When adjusting the antenna to receive signals, you need extreme care and attention. In this article, I will not give formulas for calculating the azimuth and elevation angle. A person who does not know the basics of radio engineering and radar can not understand this. It is enough only to understand that there are several satellites in orbit, and on each one there are several transceivers( transponders).Signals from different channels have different polarizations: linear( vertical or horizontal) and circular( left or right).
Therefore, when buying an antenna, you should consult the seller, which features of the settings will need to be kept in mind. He will also prompt the required diameter of the antenna, which will be sufficient for a particular point of reception of signals. It takes no more sense to acquire an antenna than necessary. In addition, the larger the mirror, the more "sail".
Read carefully the instructions on the purchased antenna and strictly follow all recommendations. Now that there is a general understanding of the installation process, it will not be difficult to do this. But the direct tuning to a high-quality signal reception is the next stage of work. Therefore, we will talk about the adjustment process a little later - subscribe to the news so as not to miss it.
