96 Saab 9-5 Audio System IB386 IB389 Antennas The Audio System has three antennas incorporated in the rear window; two for FM diversity and one for AM. 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 reception. To avoid this problem as much as possible 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 contains metal particles on the rear window, this can be the cause of radio interference. Fitting a car-phone antenna on the rear window can cause interference to radio reception. IB387
