https://devzone.nordicsemi.com/f/nordic-q-a/52418/antenna-comparison-of-nrf52840-boardsDear, I am doing some range tests with the nRF52840 and saw that the RSSI value of the PCA10059 (USB dongle) can be more than 10dB lower than the one of the PCA10056 (DK). Is this expected behaviour ? Are the radiation patterns of both antennasen-USTelligent Community 13Fri, 20 Sep 2019 14:18:32 GMThttps://devzone.nordicsemi.com/thread/210979?ContentTypeID=1Fri, 20 Sep 2019 14:18:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9827e135-0398-489a-9055-836416eaad02awneil<p>With antennas, size matters.</p> <p>The dongle is a lot smaller than the DK - so it&#39;s not really surprising.</p> <p>But there are also very many other things that can affect RSSI; unless you have the 2 devices in <em><strong>exactly</strong> </em>the same position under <em><strong>exactly</strong></em> the same conditions - including the surrounding environment - it is very hard to make meaningful comparisons.</p> <p><a href="https://devzone.nordicsemi.com/f/nordic-q-a/52112/nrf52832-rssi-varitaion/209579#209579">https://devzone.nordicsemi.com/f/nordic-q-a/52112/nrf52832-rssi-varitaion/209579#209579</a></p><div style="clear:both;"></div>
