(LTE B7/B38/B40/B41/B30)
1)
It is recommended to use a passive GNSS antenna when LTE B13 or B14 is supported, as the use of
active antenna may generate harmonics which will affect the GNSS performance.
5.3.2. Recommended RF Connector for Antenna Installation
EM06 is mounted with standard 2mm × 2mm receptacle RF connectors for convenient antenna
connection. The connector dimensions are illustrated below:
