Satellite dish antenna

Also called dish, dish antenna, tv antenna, sat dish or digital dish antenna

As soon as the signal, transponded by (for instance the Astra) satellite, reaches your home, mobile home, camper or boat, it will be captured by the satellite dish antenna. A satellite dish antenna, in short dish antenna, is an oval or circular reflector with has the form of a parabolic antenna. In the middle of the dish antenna a so called LNB (Low Noise Block-downconvertor) is mounted, which contains the actual antenna. By the dish antenna (reflector) the satellite signals are bundled and transponded to this LNB. The LNB transponds this signal to the satellite receiver by the mounted coax cable and f-connectors.

In some cases the dish antenna needs to receive the signals of multiple satellites at the same time. It's possible, when both satellites are close enough to each other, that both signals can be captured by one satellite dish antenna and only one single LNB. This may have however an (adverse) influence on the quality of the signal, because the satelite dish antenna is not directly focussed on one single satellite. This can be solved by placing multiple LNB's at the satellite dish antenna, in which each LNB is pointed at one single satellite.
