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.

FM 75

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.
2	Plug the adapter into the 75 Ω socket.

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.

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.
