Connecting an Outdoor FM Antenna

If you cannot achieve good reception with the supplied indoor FM antenna, try 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 antenna should be located away from possible noise sources, such as neon signs, busy roads, etc.

For safety reasons, outdoor antenna should be situated well away from power lines and other high-voltage equipment.

Outdoor antenna must be grounded in accordance with local regulations to prevent electrical shock hazards.

Using the 75/300-ohm Antenna Adapter

The 75/300-ohm Antenna Adapter is not supplied with American and European models.

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 75socket.

Make sure the shielding is not touching the central conductor.

5.Refit the adapter’s cover, and then plug the adapter into the 75socket.

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 circumstances 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 antenna must be grounded in accordance with local regulations to prevent electrical shock hazards.
