"Install, Aim and Repair Your Satellite TV System"

tune up your dish, find the satellites, and get the best reception. It also
will help you diagnose any problems that come along, and tells you what to
replace or tweek to get your reception back on the beam. Lots of photographs
and diagrams, IDEAL for the beginner.

IN REFERENCE TO A SATELLITE COMMUNICATIONS SYSTEM, WHAT DOES A BACKHAUL MEAN,
AND WHAT DOES IT PHYSICALLY REPRESENT??
Backhauls are signals sent from a remote location back to a network operating
center. Usually, but not always on KU band, these are special events and
sports. Since the commercials are usually added by the network, the backhaul
has no commercials, and you get to hear the announcers talk and see them play
with the video effects when the signal is not being broadcast to the world
(before, after the event and during commercial breaks).
What is needed at the backhaul site are cameras, microphones, audio and video
mixing and effects equipment, and an uplink transmitter and small dish to
send the signal to the satellite.
At the network operating center, there is a downlink (receive) dish, and
a receiver to pick up the signal, and pipe it into the audio and video chain
of the network so that it can be sent to those unlucky people who don't have
satellite dishes and have to watch these broadcasts on regular TV or Cable
