Antenna connectors confusion on the EM05-G

Technical Subjects Hardware RF/Antenna
1

Our EM05-G modules are not finding any satellite. We are wondering, if we connected the antennas correctly.

There are only 2 antenna connectors on the EM05-G, one labelled with M (probably for Main) and one labelled with D/G (maybe for Diversity AND GNSS). But in the documentation, it can be seen that the EM05-G has THREE connectors, labelled D, G and M.

Between the 2 connectors, at least on our modules, a soldering pad labelled with G can be seen, which isn’t equipped with a connector.

  • what is this for?
  • is connecting a 4G antenna to M and a GNSS antenna to D/G sufficient?

Thank you! Can I get the whole manual where this is from? Where?
This would probably be very helpful.
