The Taking

That is your receiving system must have a margin of signal – a slightly larger antenna diameter than is minimally necessary for the satellite. Recently, there are many models of combined digital-analog receivers, permit the taking of digital and analog signals on one device. They usually have two separate inputs – digital and analog. In this case we can also recommend to use the divider by two. In addition to frequency, the digital receiver, you must configure two parameters – the speed of digital Flow SR (symbol rate) and setting FEC, which characterizes the level of error correction in the digital stream.

5. The final tuning the antenna. Tighten the screws to regulate the movement of the satellite antenna in azimuth and elevation directions so as to be able to move with some force the antenna up and down and side to side, and without making efforts antenna would have remained stationary. Then start to systematically scan the sky around chosen aiming point. If you use an analog receiver and completed all the previous paragraphs is true, then eventually you will be able to 'catch' on the TV screen noisy TV signal. Making sure that you hit your desired satellite, not one of the neighboring, spend "fine" adjustment, based on the quality of television pictures. There may be a useful signal level meter – the so-called 'satmetr. " However, if you do not, do not worry. In most cases, the most popular satellite dish is quite possible to qualitatively adjust without him.
