Craig, For SIM7600, ANT1 is GPS, and ANT2 is GSM. ANT3 should not be connected. Regards, Mark

As it turns out, u.fl sockets are directional (if I had looked more closely I would have seen this). The socket I replaced at ant3 had the correct orientation but after removing it all 4 pins are still shorted together. This makes me think ant3 is not really used with a sim7600.
The socket on ant2 was reversed. Installing a new one correctly solved the short circuit but now it appears to be open and I'm still getting no signal (+CSQ: 99,99). So I guess now I need to swap the simcom module.
