10.3. FM Antenna Connections
Connect the supplied FM wire antenna or a commercially available FM antenna to the FM antenna terminal.
10.3.1. When using the supplied FM wire antenna
Connect the F-type terminal of the supplied FM wire antenna to the FM antenna terminal.
Note
Stretch the antenna straight. Install it away from metal objects that can interfere with radio signals.
10.3.2. When using the external antenna
Connect an external antenna when the supplied FM wire antenna cannot obtain good reception.
When using the 75 Ω coaxial cable such as the RG-6/U for the external antenna, attach the F-type connector
for connection.
When using the 300 Ω feeder wire for the external antenna, convert it to F-type connector using a 300 Ω to 75
Ω conversion connector, then connect it to the FM antenna terminal.
Tip
Be sure to use a 75 Ω coaxial cable when installing the tuner in areas where radio signals are weak or where
signal reception is unsatisfactory due to noise interference from motor vehicles or high-voltage cables.

The antennas can receive radio signals at the highest level
from the direction indicated by the arrow.
Position the antenna so that the arrow can face toward
broadcast stations, or orient the antenna for the best
reception by actually receiving broadcasts.
Note
When using the supplied FM wire antenna,
wrap the antenna cable around the cord clamp
to prevent the supplied FM wire antenna
connector from coming off when pulled.
