109 Saab 9-5 Audio System
AntennasThe audio system has two antennas incor-
porated in the rear window: one for FM and
one for AM.
The XM
TM
Satellite Radio antenna3 is
located on the roof of the vehicle. Keep this
antenna clear of snow and ice build up for
clear radio reception.
Roof loads can negatively affect telecom-
munication, GPS reception and the
performance of the XM
TM
system3.
If sun film is fitted to the rear window, it
must be a pure-plastic variety to maintain
good radio reception. Ensure that the film
does not contain any metal.
Multipath propagationMultipath propagation occurs when radio
waves from an FM transmitter are reflected
by a large building, or the like, causing them
to arrive slightly later than the direct waves.
This can create interference to radio recep-
tion. See also "Diversity antenna".
Diversity antenna3
33 3To improve radio reception when the topog-
raphy is a problem, a second FM antenna,
known as a diversity antenna, can be fitted
in the rear window. Consult a Saab dealer
for further information.
NOTERefrain from placing hard or sharp
objects on the rear parcel shelf, to avoid
damaging the antenna leads.

110 Saab 9-5 Audio SystemShadow effectBecause 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.
Cross modulationIf the radio is tuned to a weak transmitter in
the vicinity of a stronger one, the car’s
antennas will receive signals from both.
Such interference is apparent when the
unwanted broadcast can be heard faintly in
the background.
Radio waves, FM/AMFM radio waves radiate in straight lines from
the transmitter. Because such waves do not
follow the curvature of the Earth, their
strength becomes weaker the further they
travel. That is why a large number of trans-
mitters is needed to provide good reception.
AM waves, on the other hand, are reflected
off the ionosphere, thus greatly extending
their range.
