CONNECTIONS FOR YOUR TV (CONTINUED)
ANTENNA REQUIREMENTS
Your TV contains the most advanced television
technology available today. We recommend that only an
outdoor all-channel antenna, Master TV antenna or
CA TV cable input be used.
If
an antenna is used, it
should be terminated in a 75 ohm lead-in to your TV.
OUTDOOR ANTENNAS
A TV antenna is really a "net" to catch waves transmitted
by a TV station. A good picture on your television set
depends on how well your antenna captures the waves
radiated by the TV stations.
Your Zenith TV
will
work in most locations on an
outdoor antenna. The quality of your picture may
·
depend on a) the proper antenna, in good working order,
b) how far you are from the television transmitters and,
c) the nearness of such obstructions as tall buildings,
towers, or mountains. An outdoor antenna pulls in more
signal to produce the best picture and reduces or
eliminates problems created by weak reception.
WHEN YOU NEED A NEW OUTDOOR ANTENNA
No matter what kind of TV roof antenna you have,
if
it is
several years old, it is probably oxidized, coated with
grime, and possibly wind-damaged. The result may be
somewhat fuzzy TV picture lacking in color and even
showing "ghosts." Also, antenna design improvements
since your old antenna was installed may have made it
obsolete.
SELECTING A NEW OUTDOOR ANTENNA
Local TV reception conditions vary greatly. Your best
source of advice about the most effective antenna for
your area is your Zenith dealer or Distributor-approved
Zenith Service Center representative, whose
recommendation
will
be based upon years of local
experience.
ANTENNA SIGNAL BOOSTERS (AMPLIFIERS)
If you have a severe fringe-area problem, the solution
may be a signal booster (amplifier). The signal booster is
installed between the antenna and the TV, usually next to
the antenna, in an attic. It magnifies incoming signals to
provide a better picture and is available as an optional
accessory from your local Zenith dealer.

Check your outdoor antenna from time to time to see
that it is not wind-damaged. Inspect the lead-in cable for
cracks, or other damage. Antennas with missing
elements or a poor lead-in cable are a prime cause of
poor picture reception. Replace the antenna or lead-in
cable
if
necessary. Professional installation of the
antenna or antenna components is recommended. As
described in the subsequent paragraphs on antenna
installation, it is hazardous work and can result in fatal or
crippling falls.
People who have owned a TV for several years shrug off
less-than-perfect pictures, blaming them on the age of
the TV. They are pleased to discover that a new outdoor
all-channel antenna suddenly brings their TV screen to
life with bright, sharp, colorful pictures. See your Zenith
dealer for a full line of 75 ohm antennas.
Generally, the more elements in the antenna array, the
more signal it can capture. Small VHF units may have
only 8 elements. Large units for deep fringe area
reception may have as many as 70 or more elements.
If
you use two or more TVs on the same antenna, its signal
must be divided between each TV with a signal splitter
( optional) available from your Zenith dealer.
If
you
operate more than one TV, the antenna may need to be a
little larger.
The signal booster is especially useful for motels, clubs
and other places operating a number of TVs from one
antenna, since it boosts signal strength sufficiently to
provide a good picture on each TV, and saves the
installation of additional antennas.
