CONNECTING AN OUTDOOR
ANTENNA
The supplied antenna provides good reception
in most areas. But, for the best reception in all
areas, use a high-quality outdoor antenna, avail-
able at your local RadioShack store.
• If the antenna uses 75-ohm coaxial cable,
connect the antenna’s cable directly to the
Model 28’s
ANT.
terminal.
• If the antenna uses 300-ohm cable, use the
supplied 300-to-75-ohm matching trans-
former to make the connection.
• If you have separate VHF and UHF anten-
nas, connect the antenna cables to a split-
ter/combiner (such as RadioShack Cat. No.
15-1296). Then connect the splitter/com-
biner’s output to the
ANT.
terminal.
Refer to your antenna’s installation instructions
for additional information.
CONNECTING TO A CABLE
SYSTEM
Note to the CATV system installer:
This reminder is provided to call the CATV sys-
tem installer’s attention to Article 820-40 of the
National Electrical Code that provides guide-
lines for proper grounding and, in particular,
specifies that the cable ground shall be connect-
ed to the grounding system of the building, as
close to the point of cable entry as practical.
To receive cable channels, connect the Model
28 to your local cable system as follows.
Caution:
Some areas have laws restricting di-
rect connections to cable wires (connections
that do not go through the cable box). Check the
laws in your area before making any connec-
tions.
If you do not receive scrambled channels
,
you can connect the cable directly to the Model
28’s
ANT.
terminal.
If you receive scrambled channels
, you must
connect the cable to the cable converter box,
then connect the cable converter box to the
Model 28’s
ANT.
terminal.
Set the Model 28 to the cable box’s output chan-
nel (3 or 4) and use the cable box to select the
channel.
