FM ANTENNAS

For the best FM sound quality. it is necessary to install an appropriate type of antenna. Consideration should be given to the signal

strength of the broadcast station and the surrounding conditions.

Indoor FM Antenna

For nearby FM stations:
Use the FM dipole antenna supplied with the receiver tor the
reception of local stations.

NOTE:

Every antenna has a directional characteristic (its ability to pick
up signals varies according to its orientation).

Spread the T-section oi the FM dipole antenna. Rotate it in order
to determine the best signal-receiving position and then install it
in that position.

Outdoor FM Antenna

In areas relatively near FM stations:

In case the supplied FM dipole antenna iails to eliminate noise
interference, or if you want to pick up signals from distant stations.
install a multi~elernent outdoor antenna.

Directional characteristics oi outdoor FM antennas:

The more elements an FM antenna has. the more sensitive and
directional it is. This type of antenna must be positioned accurately
ior the best reception of a particular broadcast station.

NOTE:

Generally. the sensitivity of an outdoor FM antenna is proportional
to the number oi its elements. This should be considered when
selecting an FM antenna.

Multlpath Distortion

A mountain or high-rise building will reilect FM radio waves Ii this
happens near an FM antenna. the reflected radio waves may inter-
iere with the radio waves reaching the antenna directly. causing
noise and sound interference. This is called multipath distortion.
This problem can be reduced or eliminated by accurately position-
ing the FM antenna.

General lnlorrnatlon 0n FM Antennas For Outdoor Instal-
latlon

Keep the following in mind when installing an FM antenna

outdoors:

1) lnstalltheamennaawayirom madtraificandplacethe antenna
as high above the ground as possible.

2) Determine the best antenna position in relation to nearby build-
ings and trees.

3) Keep the antenna away from high-voltage power lines.
