Gl-X750-v2c6 - Antennas..?

Hello All

Looking for some advice / guidance

It is my understanding that the “2” External antennas screwed on with SMA are purely for 4G/LTE
The Wifi is Internal, the small little separate PCB

Does anybody know…??
What are the “2” connectors with nothing connected, are they MCX/IPX.??, no markings.
1 is just to right of WiFi connector, the other to the left of 4G/LTE connectors

Many Thanks… Dave

Yes you are right.

They are for radio calibration.

Hi alzhao…

Many thanks…
Was hoping I could mod the case and attach external WiFi Antennas…!!

Cheers…
