How Does Digital Satellite System
TV Work?
Satellite programming originates from an “uplink”
facility on Earth — the facility receives many signals
from different sources, combines the signals digitally
and transmits to the satellites. The satellites (22,300
miles above Earth) receive the uplink signal, amplify
it and then transmit it back to earth in the Ku fre-
quency band. This signal is received by your
satellite antenna whose shape reflects and concen-
trates the signal to the LNBF*
attached to the antenna. The
LNBF is located at the “focal
point” of signal reflection, that is,
the point at which the maximum
amount of signal is effectively
concentrated. The LNBF amplifies and
converts the signal to the 950 to 1450
MHz range. The signal is then passed
through a coaxial cable to the elec-
tronics box, then to the receiver where
individual channel selection and pro-
cessing take place.
