5 Antenna Interfaces
EM05 includes a main antenna interface, 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. The
antenna interfaces have an impedance of 50Ω. And the GNSS antenna interface is optional.
The antenna interfaces are shown below.
