Poor radio recep-
tion:
The radio tuner finds
no broadcaster or the
reception is poor.
For problem-solving regarding the radio reception it is
important to know the type of the antenna of your vehicle.
Here are the possible solutions for each type of the antenna:
Type 1
– passive antenna:
We recommend you to substitude the existing antenna by the
larger and therefore more efficient one.
Shark fin or rod antennas (under 5 cm) are definitely insuffi
-
cient.
Type 2
– active antenna:
The vehicle provides no current for the active antenna. In this
case a phantom power is required, which provides the active
antenna with the external power supply.
Type 3
– active antenna with diversity system:
The unit provides no current for the active antenna and has
no diversity support. For this type of antenna is required the
phantom power with an integrated diversity system.
Note:
A phantom power is not to be confused with an antenna
amplifier, which is far less efficient.
