Connecting the indoor FM antenna
Connect the included indoor antenna to the 75
Ω
UNBAL. FM
ANT terminal.
Note
Do not use an outdoor FM antenna and the indoor FM
antenna at the same time.
GND terminal
For maximum safety and minimum interference, connect
the GND terminal to a good ground. A good ground is a
metal stake driven into moist earth.
Ⅵ
Optional outdoor FM antenna
Consult your dealer or authorized service center about the best
method of selecting and erecting an outdoor FM antenna.
The choice of the flat ribbon cable is also important. Flat ribbon
cable performs well electrically, and is cheaper and somewhat
easier to handle when routing it through windows and around
rooms. Coaxial cable is more expensive, does a much better
job of minimizing interference, is less prone to the effects of
weather and close-by metal objects, and is nearly as good a
signal conductor as flat ribbon cable. Coaxial cable is
somewhat more difficult to install at the point where the cable
enters the building. If coaxial cable is selected, make sure the
antenna is designed to be used with this type of cable.
* Use a 75-ohm/300-ohm antenna adapter (not included) or a
75-ohm antenna adapter (not included) for connections.

Notes for FM antenna installation
● To minimize the influence of automobile ignition noise,
locate the antenna as far from heavy traffic as possible.
● Keep the flat ribbon cable or coaxial cable as short as
possible. Do not bundle or roll up an excess of the cable.
● The antenna should be at least two meters (6.6 feet) from
reinforced concrete walls or metal structures.

If this unit is placed in steel buildings or an area far from
broadcasting stations, it may be necessary to install an outside
long wire antenna.
