Selecting an antenna cable
The antenna requirements for good color
television reception are more important than
those for black and white television reception.
For this reason, a good quality outdoor antenna
is strongly recommended.
The following types of connectors are used with
various antenna systems:
• A 75-ohm system is generally a round cable
with F-type connector that can easily be
attached to a terminal without tools.
• A 300-ohm system is a flat twin-lead cable
that can be attached to a 75-ohm terminal
through a 300-75-ohm adapter.
Connecting to an antenna or cable
television
Connecting without a cable or satellite box
A 75-ohm coaxial cable connector is built into
your television for easy hookup. When
connecting the 75-ohm coaxial cable to the set,
screw the 75-ohm cable to the antenna jack.
Connecting with a cable or satellite box
For subscribers to scrambled cable TV
service
If you subscribe to a cable service which
requires the use of a converter/descrambler box,
connect the incoming cable to the converter/
descrambler box and connect the output of the
box to the antenna jack on the back of your
television. Follow the connections shown in the
following diagram. Set your television to the
output of the converter/descrambler box (usually
channel 3 or 4)and use the converter/
descrambler box remote control to select
channels.
For subscribers to unscrambled basic cable
with scrambled premium channels
If you subscribe to a cable service in which basic
cable channels are unscrambled and premium
channels require the use of a converter/
descrambled box, you may want to use a two-set
signal splitter (sometimes called two set coupler)
and an A/B Switch box from the cable installer or
an electronics supply store.
