The Nokia G-140 actually does have two antennas. The vacant port you cite is not where an antenna should be. The second antenna is tracked into the right hand side of the PCB. You can see it. The vacant port you cite is in line to that antenna, and is used for factory testing of the product, for conducted performance of the track to the antenna. The connector disconnects the PCB antenna when the automatic test equipment engages with that connector unit, and reconnects when the test equipment releases from that connector. This is standard practice in the industry.
If no second antenna was being fitted, Nokia wouldn’t have bothered to fit the connector either. They cost money, and they wouldn’t have fitted the connector to the unit and then not fitted an antenna. that makes no sense. The 2nd antenna is the PCB tracked antenna.
