Aerial system for radios

The chorus, concert and symphony radios have
FM tuners with phase diversity (refer to SSP 382,
TT Coupé ‘07 - Infotainment). These radios have
two aerial inputs. The aerial amplifier R24 is
connected to aerial input 1.
Both FM and AM aerial signals are received via this
connection.

Aerial amplifier R24 is integrated in the base
of the stub aerial.
Aerial input 2 receives only FM signals and is not
connected to aerial amplifier -2- in the luggage
compartment on the rear right. Aerial amplifier -2-
receives signals from the metal-plate aerial behind
the rear cross panel on the right.

The BNS 5.0 and RNS-E radio navigation systems
have FM tuners with switched diversity.
In these radios, aerial switching takes place in an
external aerial amplifier with aerial selection.
The radio has an aerial input (HF signal) and a signal
output (IF signal).
The IF signal is evaluated by an aerial amplifier.
If the signal is too weak, this aerial amplifier
switches to the other aerial.

In vehicles equipped with a radio navigation system
without TV tuner, the serial selection function is
integrated in aerial amplifier -2- R111.
Aerial amplifier -2- R111 receives signals from both
radio aerials and can switch between both aerials
when FM reception is desired. When AM reception
is desired, aerial amplifier -2- R111 is always
switched to the stub aerial.

For TV reception, a total of 3 aerials with 3 aerial
amplifiers are fitted. The metal-plate aerial serving
as FM aerial 2 is also used as aerial 1.
Aerial amplifier -2- R111 splits radio and TV signals
and sends the TV signals to aerial input 1 of the
TV tuner.
TV aerials 2 and 3 are integrated in the windscreen.
There is an aerial amplifier in each of the A-posts.
These amplifiers sends the aerial signals to the
TV tuner in the luggage compartment at the rear
right.
A TV tuner is not available yet, and likewise this
aerial system.

The Navigation plus system (RNS-E) has an
FM tuner with switched diversity. If an auxiliary
TV tuner is fitted in the vehicle, an aerial selection
control unit J515 for switching the radio aerials is
installed in the luggage compartment at the front
right.
The aerial selection control unit receives signals
from the two aerial amplifiers R24 and R111 and
can switch between the two aerial amplifiers when
FM reception is desired. When AM reception is
desired, the aerial selection control unit J515 is
always switched to the aerial amplifier R24.
