Antenna Connection

5.1. Antenna Connectors

EG25-G Mini PCIe is mounted with three antenna connectors for external antenna connection: a main
antenna connector, an Rx-diversity antenna connector, and a GNSS antenna connector. And Rx-diversity
function is enabled by default. The impedance of the antenna connectors is 50 Ω.
