Satellites, Coverage maps satellite

Coverage Map gives a graphical projection of the satellite signal is distributed antennas to the territory of land, and because the characteristics of the emitted signal is not linear, then the characteristics of the signal and its level should be studied on the map to cover a particular satellite. These maps are also gradations of signal in areas away from the center of radiation. Choosing diameter satellite dish installation, you need to follow coverage map for the desired satellite, determine the coverage and coverage area for your antenna diameter. Since the signal is represented in decibels, then you must use the tables to determine the appropriate diameter of the antenna, which will provide confidence, and it would be uncomfortable to watch TV programs. The table below zavisimotsey diameter satellite antenna on the signal strength in dB, providing reliable reception of satellite broadcasts for Ku-band (left) and C-band (right). Convectors reception with different characteristics ratio, it should be taken from the passport convector
