How a Satellite Dish Works

By: John Crowe

Are you thinking about getting Dish Network or another satellite TV supplier but are unclear how a satellite dish works? Here’s your answer.

A Satellite Dish is an antenna designed to target a particular broadcast source and could be a main component of satellite TV providers, like Dish Network. The quality satellite Dish Network dish consists of a parabolic (bowl-formed) surface and a central feed horn. A controller sends it through the horn, and therefore the Dish Network satellite dish focuses the signal into a comparatively slender beam. A narrow beam is generated as the dish reflects energy from the feed horn. The Dish Network satellite dish on the receiving finish will only receive data; it cannot transmit information. The receiving dish works in the precise opposite approach of the transmitter. When a beam hits the curved dish, the parabola form reflects the radio signal inward onto a particular point, just sort of a concave mirror focuses light onto a explicit point. The curved dish focuses incoming radio waves onto the feed horn.

The feed horn then passes the signal onto the receiving equipment. Ideally, there will be no obstructions, like trees to interfere with the signal from the satellite to the Dish Network satellite dish. With no obstructions you receive a much clearer signal.

Some systems are set up to receive signals from more than one satellite. A replacement dish style uses 2 or more horns to pick up totally different satellite signals. As the beams from different satellites hit the curved dish, they mirror at totally different angles therefore that one beam hits one of the horns and another beam hits a different horn.

The central component within the feed horn is the LNB (low noise blockdown converter) The LNB amplifies the radio signal bouncing off the dish and filters out the noise (radio signals not carrying programming). The LNB passes the amplified, filtered signal to the satellite TV receiver inside the viewer's house.

A cable is run from the Dish Network satellite dish into the house and then connects to the satellite TV receiver (black box) therefore completing the connection.
