ONE+ Model H External Antenna
Posted: Sun Jan 31, 2021 3:24 pm
The SIM7600E-H board has two hirose connectors. One is connected to the main (cell) antenna input and has a pigtail to an antenna on the back of the case. The aux antenna looks to have an antenna embedded on the PCB. There is a second hirose connector. I assume it is for GPS. Based on low resistance to VDD I assume it is potentially designed for an active external GPS antenna. Can anyone confirm that?
