Connecting an Outdoor FM Antenna

If you cannot achieve good reception with the supplied
indoor FM antenna, try using a commercially available
outdoor FM antenna instead.
Notes:
• Outdoor FM antennas work best outside, but usable results
can sometimes be obtained when installed in an attic or loft.
• For best results, install the outdoor FM antenna well away
for tall buildings, preferably with a clear line of sight to your
local FM transmitter.
• Outdoor antennas should be located away from possible
noise sources, such as neon signs, busy roads, etc.
• For safety reasons, outdoor antennas should be situated well
away from power lines and other high-voltage equipment.
• Outdoor antennas must be grounded in accordance with local
regulations to prevent electric shock hazards.
Using the 75/300 ohm Antenna Adapter
(Australian model only)
The 75/300 ohm antenna adapter can be used to connect
an FM antenna using either 75 ohm coaxial cable or
300 ohm twin-core flat cable.
Connecting 300 ohm Flat Cable
1
Using a screwdriver, loosen
the two screws on the adapter,
wrap the bare wires around the
screws, and then retighten
them, as shown.
Plug the adapter into the 75 Ω socket.
2
Connecting 75 ohm Coaxial Cable
1 Strip and prepare the
75 ohm coaxial cable, as
shown.
2 Using your fingernails or a small screw-
driver, lever the adapter's tabs outward
and remove the cover, as shown.
3 Move the small wire inside the adapter
from position A to position B, as shown.

shown, and use a small pair of pliers to
clamp the shielding and outer insulation
sections of the cable (
Make sure the shielding is not touching the cen-
tral conductor.
5
Refit the adapter's cover, and then plug
the adapter into the 75 Ω socket.
Using a TV/FM Antenna Splitter
It's best not to use the same antenna for both FM and TV
reception, as this can cause interference problems. If circum-
stances demand it, use a TV/FM antenna splitter, as shown.

Connecting an Outdoor AM Antenna

If good reception cannot be achieved using the supplied
AM loop antenna, an outdoor AM antenna can be used
in addition to the loop antenna, as shown.

Outdoor AM antennas work best when installed outside
horizontally, but good results can sometimes be obtained
indoors by mounting horizontally above a window. Note
that the AM loop antenna should be left connected.
Outdoor antennas must be grounded in accordance with
local regulations to prevent electric shock hazards.
