How a Satellite Dish Works
New Product 2009 ! www.ICPC.TV
Are you planning on purchasing a Satellite reception system from Dish Network or another satellite TV seller but are doubtful about the way a satellite dish is working? Here is your answer.
A Satellite Dish is an antenna designed to accept the broadcast and is a main component of satellite TV providers, such as Dish Network. The usual satellite dish of Dish Network and other providers is made of a parabolic (bowl-shaped) surface and a middle feed horn. A regulator sends the received Radio or TV signal from the satellite via the horn, and the dish focuses the signal into a rather thin beam. The narrow beam is generated as the dish reflects energy from the feed horn. The dish antenna at the receiving (in which the customer or the TV is situated ) end may only receive information like TV programs , it cannot send out information. The receiving satellite dish works in the precise opposite method of the Dish on the transmitter side. When a beam hits the rounded dish, the parabola mold reflects the radio signal inwardly onto a specific point, just like a concave mirror focuses light onto a precise position. The curved satellite dish adjusts the received radio waves onto the feed horn.

The feed horn then passes the signal onto the receiving equipment. Ideally, there will be no obstructions, such as trees to interfere with the signal from the satellite to the Dish Network satellite dish. With no obstructions you receive a much clearer picture or Radio .
Some systems are set up to receive signals from more than one satellite. A new dish invention uses two or additional horns to pick up various satellite signals, from various directions . As the beams from various satellites hit the curved dish, they reflect at diverse angles so that one beam hits one of the horns and another beam hits a different horn.
The vital part in the feed horn is the LNB (low noise block down converter) The LNB amplifies the radio signal reflecting off the dish and filters out the noise (radio signals not carrying programming). The LNB transfers the amplified, filtered signal to the satellite TV receiver within the viewer's house.
A cable called coax is running from the Dish Network satellite dish into the home and then links to the satellite TV receiver (black box) thus finishing the connection.
