The curved dish focuses incoming radio waves onto
feed horn. The feed horn then passes
signal onto
receiving equipment. Ideally, there will be no obstructions, such as trees to interfere with
signal from
satellite to
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 new dish design uses two or more horns to pick up different satellite signals. As
beams from different satellites hit
curved dish, they reflect at different angles so that one beam hits one of
horns and another beam hits a different horn.
The central element in
feed horn is
LNB (low noise blockdown converter) The LNB amplifies
radio signal bouncing off
dish and filters out
noise (radio signals not carrying programming). The LNB passes
amplified, filtered signal to
satellite receiver inside
viewer's house.
A cable is run from
satellite dish into
house and then connects to
satellite TV receiver (black box) thus completing
connection.
