https://devzone.nordicsemi.com/f/nordic-q-a/21084/nrf52840-dk-alternate-antennaHi, I would like to use higher dBi antenna instead of the DK pcb antenna. Can I say the pi-network before J1 (measurement point) probe is 50ohm? Hence I can just remove the J1, solder u.FL connector on that location?

The connector, J1, is placed in the 50 Ohm reference point. The matching network for the antenna consists of C15.</p><div style="clear:both;"></div>
