FM RDS reception si 4749


We are currently developped a project called LampeaNantes. The goal is to power up town light with a proprietary ODA on FM RDS capability. We experienced some difficulties to receive RDS in town light box, regarding the default configuration, is there any ways to tune SI4749 to achieve better reception : différents thresholds RSSI, multipath, AGC Attack, ...

As antenna, we use a coaxial cable :

SI4749 FM input is 50 ohms

Is there recommended antenna brand?

As attachement the schematic.

Thanks for your help

Best Regards
