DTH receiver at the Subscriber's premises


The receiver consists of a parabolic dish antenna of 50 or 60 CM diameter. This dish is mounted on a wall such that it looks at the required satellite. There should not be any obstruction like building or trees in the path between the antenna and the satellite. The signal from the satellite is reflected by the parabolic dish towards a point called focus just like a concave mirror focuses the light. At the focus, if Eid hall is mountain that collects the forecast signal. At the feed on is mounted and equipment known as low noise block converter (LNBC). This amplifies the receive signal and converts the Ku band frequency to 950 megahertz to 2150 megahertz which is called the L-band. The dish antenna and feed horn with LNBC are outdoor units point the output of the LNBC is connected to the set-top box which is mounted inside the house through a cable.

The receiver decodes the encrypted signal. The digital MPEG - 2 are MPEG - 4 signal is converted to analogue format so that a standard television can recognise it. The video and audio output is connected to the AV Input and TV receiver.
