I’m looking at the GL-X750V2 and see it has two antenna rods. I gather these are for incoming signal, not wifi. It says they can be screwed off but doesn’t say what the connectors are. I run MIMO yagi which has male-ended SMA cables from the mast. What connector does the GL-X750V2 have and what is the male/female on the connector and the connector type?
You are right. They are not for wifi, only for LTE.
LTE antenna type should always be standard SMA. I don’t have X750V2 at hand, but it should be Standard SMA female.
