Because it disconnects the on board antenna, so you can do conducted measurements or connect an external 50 Ohm antenna.&nbsp;</p> <p></p> <p>Best regards,<br />Kaja</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/457525?ContentTypeID=1Mon, 27 Nov 2023 10:45:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2b37403d-acad-4e6b-a002-d48f3af95705Eau Du Puid<p>Hi Kaja</p> <p>Thanks, so the connector named &quot;LTE RF measurement connector&quot; is in fact not only for measurements ?

This can be connected with a connector on the pcb, to the antenna/LTE ant pin on the nRF9160.<br /><br />See our WP: <a href="https://infocenter.nordicsemi.com/pdf/nwp_033.pdf">nRF9160 Antenna and RF Interface Guidelines&nbsp;</a></p> <p>Best regards,<br />Kaja</p><div style="clear:both;"></div>
