Aerial diversity
In the E85, 2 physical aerials are connected to the radio aerial
diversity, i.e. the rod aerial and the aerial in the bumper. The
aerial diversity function switches over to another aerial as soon
as the system undershoots a defined threshold.
Changeover takes place in such a way that no interruption can
be heard.
Depending on the reception situation, reception on both aerials
simultaneously is also possible.
E85 Information/Communication
The aerial amplifier is designed
for FM reception. The aerial
amplifier is connected to the
aerial diversity by means of a
coaxial cable.
