Single aerial
The R 100 radio has a single aerial in the front
windscreen and an aerial amplifier.
Diversity aerials
Two independent aerials (Diversity aerials) can reduce reception interference like noise and crackling,
for example, in conjunction with the 2-tuner FM Diversity or the control unit for aerial selection (external
change-over box). This interference occurs frequently in residential areas or mountainous regions due to
reflection from houses and mountains. The reflection causes the signals to be delayed and leads to
interference.
2-tuner FM Diversity system
The RCD 300 radio has an integrated
2-tuner FM Diversity system with two internal
receivers that process the incoming aerial signals
separately and combine them to make a single
signal.
Control unit for aerial selection
The J515 aerial selection control unit (external
switch-over box) allows connection of the
Diversity aerials to the RNS MFD-2 radio
navigation unit. This monitors the incoming
aerial signals on the external switch-over box
and automatically switches to the aerial with the
stronger signal.
