5 Antenna Interfaces
EG95 antenna interfaces include a main antenna interface and an Rx-diversity antenna interface which is
used to resist the fall of signals caused by high speed movement and multipath effect, and a GNSS
antenna interface which is only supported on EG95-NA/-EX/-NAX/-AUX. The impedance of the antenna
ports is 50 Ω.
