Using the External Antenna Connector (MM8130–2600) on an external antenna.

Question

Hello! 
 
 We are planning on using the nRF52832 DK together with an external antenna. We are highly interested in the readings being as accurate as possible, and we are wondering about; 
 
 1, Is there a standard or a suitable cable that can be used together with this connector -> coax? 
 2, Referencing to this post: ( https://devzone.nordicsemi.com/f/nordic-q-a/52623/switch-antenna-connector ), where the first reply mentioned that the connector is not suitable for an end product, and its more of a test connector. How do we make this connector reliable, or do we have to solder on a extra connector for coax? 
 
 Thank you in advance!

Hi Anders, 
 
 MXHS83QE3000 is a test cable which fits the MM8130-2600 SWF connector. 
 But the main problem with using this connector for a and product is that the test cable is not secured in the connector, and any stress put on the cable will result in the cable being disconnected from the connector. 
 Your main options are to remove the SWF connector and either replace it with a U.FL connector or solder a coaxial cable to the 50 Ohm transmission line. 
 When we take conducted radio measurements of customer devices we cut the transmission line after the radio matching network and solder a rigid coaxial cable to the transmission line. In order to get good connection the outer ground of the coaxial cable is soldered to the ground plane close to the transmission line. 
 
 Best regards,
