System function RTTI splitter
The antenna output is divided asymmetrically. The IBOC tuner receives a signal attenuated by 1 dB, the head unit a signal attenuated by 10 dB. The level delivered by the active FM antenna is this divided in a ratio of 9:1 (IBOC:RTTI). The antenna output is divided by the splitter with a ratio of 10:1 (IBOC:RTTI). This division of the antenna output is adequate for the CCC to receive the RTTI Data received. The antenna diversity is controlled by the IBOC control module.
