https://devzone.nordicsemi.com/f/nordic-q-a/65965/external-gps-antenna-nrf9160-dk-v0-8-2Hello everyone. I know from Errata document that the GPS antenna soldered on DK is not working properly on the 0.8.2 version of the DK. I need to use GPS for time syncronization using PPS signal. I don&#39;t have a mxhs83qe3000 connector for conecting anen-USTelligent Community 13Mon, 21 Sep 2020 23:12:33 GMThttps://devzone.nordicsemi.com/thread/270698?ContentTypeID=1Mon, 21 Sep 2020 23:12:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0044d6da-6b8d-4791-b1a9-eb0ebbc4e0e4WassimZ98<p>Thanks, it worked!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/270488?ContentTypeID=1Mon, 21 Sep 2020 08:27:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8e51081f-75d7-4890-9c44-8643b9d4e40cketiljo<p>Shielding the antenna will make it worse.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/270367?ContentTypeID=1Fri, 18 Sep 2020 14:38:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3d2d6003-20c9-400e-9d3b-48f6557a9eb6WassimZ98<p>In theory, doesn&#39;t that improve antenna performance?

Or, is it a way to reduce the on-board antenna coverage, maybe putting some objects on it? Do you have any suggestion?</p> <p>The problem of the test cable is that it may take long time to arrive</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/270301?ContentTypeID=1Fri, 18 Sep 2020 10:48:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b1dfe0ea-ed17-42f9-b9fe-cb45ac88449cketiljo<p>That&#39;s more difficult. It&#39;s probably easier to get the test cable:&nbsp;</p> <p><a href="https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.digikey.com%2Fproducts%2Fen%3Fkeywords%3DMXHS83QE3000&amp;data=02%7C01%7CKetil.Aas-Johansen%40nordicsemi.no%7Cdfa0ff19c9984b41a52708d85ae35284%7C28e5afa2bf6f419a8cf6b31c6e9e5e8d%7C0%7C0%7C637359279676768542&amp;sdata=zr6lL92tlRctu5rJnonvDJBGVWXUgIZLWO8YHqIPdRs%3D&amp;reserved=0">https://www.digikey.com/products/en?keywords=MXHS83QE3000</a></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/270174?ContentTypeID=1Thu, 17 Sep 2020 17:59:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b887a79d-37f3-4beb-a99b-ed90ee546ea5WassimZ98<p>Thank you very much for the answer. And what about J1 connector for LTE antenna? I need to attenuate the coverage in order to assess the power consumption, so I need to connect an attenuator to the DK. How can i do this without SWF connector? Thanks</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/269842?ContentTypeID=1Wed, 16 Sep 2020 11:17:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6e3c97b0-388d-4bcf-9431-7d569e875891ketiljo<p>That may not be that easy. The external antenna most likely have a LNA that needs power. This is supplied in the coax cable via a bias tee. Also, the LNA on the DK ideally needs to be bypassed. You should be able to feed power to an external antenna if you connect a 68 nH inductor between SB1 and J6. Cut the track between J6 and L3 and place a 39 pF cap. The idea to replicate the schematic from a newer DK:&nbsp;<a href="https://infocenter.nordicsemi.com/topic/ug_nrf91_dk/UG/nrf91_DK/gps.html#gps">https://infocenter.nordicsemi.com/topic/ug_nrf91_dk/UG/nrf91_DK/gps.html#gps</a></p> <p>L10 and C26</p> <p>You can replace J6 with a more suitable connector.</p><div style="clear:both;"></div>
