Does it make sense if I disolder J1 and solder directly the antenna to the pad?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/60870?ContentTypeID=1Wed, 24 Aug 2016 11:42:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0094149b-ce33-482e-94a8-7a943e5d0d8aHung Bui<p>Hi,</p> <p>The DK has a SWF connector (J1, part number: MM8130-2600) that you can connect to your external antenna. Make sure you antenna is tuned with 50 Ohm impedance.</p><div style="clear:both;"></div>
