I need an external antenna 60’ high for my current ATT hotspot and want to use it for my new TMO-G4AR which I hope can replace the ATT box. The T-Mobile instruction manual does not give any detail about the 4 external antenna connectors on the TMO-G4AR other than how to connect it to their own 4 connector antenna.
Which 1 or 2 connectors should I use? I was using 2 on my ATT box. Is there any explanation of what the 4 external connections do?
Thanks,
