96 Saab 9-5 Audio System
Antennas
The Audio System has three antennas
incorporated in the rear window; two for FM
diversity and one for AM.
Fitting a car-phone antenna on the rear
window can cause interference to radio
reception.
Multipath propagation
Multipath propagation occurs when radio
waves from an FM transmitter are reflected
by, e.g. large buildings, causing them to
arrive slightly later than the direct waves.
This can create interference to radio recep-
tion. To avoid this problem as much as pos-
sible the system is equipped with two FM
antennas, so called FM diversity.
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 propagation path from the
transmitter to the car.
NOTE
Refrain from placing hard or sharp
objects on the rear parcel shelf, to avoid
damaging the antenna leads.
Do not use sun protective film which con-
tains metal particles on the rear window,
this can be the cause of radio interfer-
ence.
