Antenna Connectors 7 and 8





Radio navigation system is equipped with an antenna diversity function for terrestrial radio reception. Both antenna connections are signal inputs. In radio navigation system, it is continuously analyzed via which of the two connected window antennae receives the better reception signal. It then switches to the antenna with the better reception signal. This is not audible to the customer.
