Antenna
The antenna of the Audio System is motor-
ized.
Saab 9-3 Viggen Coupé and 5-door: The
antenna is located on the roof.
NOTE
Remove the antenna if you wash the car
in a car wash, to avoid it being damaged.
For the cleaning of the motorized antenna,
see the section headed "Washing", page
226.
The car has a factory-fitted roof antenna for
a car phone. Roof loads may negatively
affect telecommunication.
Multipath interference
When the radio waves from an FM transmit-
ter collide with a large building, for example,
they will be reflected so that they reach the
car antenna slightly later than the direct
waves. This is referred to as multipath dis-
tortion. The effect is liable to be blamed
upon malfunctions in the radio.
Saab 9-3 Audio System
Shadow effect
Because FM radio waves travel in straight
lines from the transmitter, a shadow effect
can occur when tall buildings or hills
obstruct the interference path from the
transmitter to the car.
