I have a GL-X750 with EC25 LTE module. I would like to get a higher gain 2.4Ghz wifi antenna and attach it one of the external SMA connections. I’ve taken the router apart and noted both SMA connections connect to the LTE module, ports MAIN and DIV.
Am I able to disconnect the LTE modules DIV UFL cable and attach to the boards wireless UFL interface without damaging the LTE module? In other words is the LTE module smart enough to know the DIV antenna is unplugged and not TX out that interface?
