Antenna: Description and Operation

Integrated Antenna System

The Cayenne employs an integrated antenna system for audio, central locking system, navigation. telephone and parking heater. There are differences between two available antenna Systems: the Basic system and the Diversity system.

The central locking antenna is always part of every system. However, antennas for the parking heater remote control, the navigation system and telephone antenna can be installed depending upon vehicle equipment.

Up to 13 non-visible antennas can be installed in the rear area of the Cayenne. Electronic components such as antenna amplifier, diversity control module and GPS antenna are located in the rear spoiler.

All components in the rear spoiler are waterproof.

Components, particularly the GSM and GPS antenna, have been optimally located in the spoiler. The high placement considerably enhances the signal reception. This results in wider range and less interference.







Base Antenna System

The base antenna system consists of a 70 cm long antenna injected into the lower shell of the spoiler. The related AM/FM antenna is positioned to the right in the spoiler.

Antenna Diversity

Antenna Diversity belongs to the PCM product range. The system is made up of the base system AM/FM antenna as well as 3 additional FM antennas integrated into the rear window. Antenna Diversity has a single standard AM amplifier and 2 FM antenna amplifiers.

Two modules are integrated into the spoiler. On the right is the Antenna Diversity control module, and on the left is the second module with the 2 FM antenna amplifiers.

This system ensures that the best-positioned antenna always receives the FM signals. The system is not designed for AM reception, since switching the antennas would create audible interference. If one antenna does not have an adequately usable signal or has too much interference, the switch is made to another antenna. One of the antennas is specified as the primary antenna and is activated directly. Quality fluctuations in this wave band are further minimized in this way.
