I&#39;m guessing it&#39;s not an issue most of the time, because the feature is designed to test transmitter circuits and firmware (i.e. to see how clean/stable and agile the signal generation is, and perhaps some low-level protocol decoding) instead of antenna performance. For antenna performance, I guess there&#39;s no need to do a decode or view eye diagram.</p> <p>The board orientation looks good to me too, it&#39;s what will provide a similar oriented and shape radiation pattern to the other antenna in the photo.</p><img src="https://community.element14.com/aggbug?PostID=23916&AppID=13&AppType=Weblog&ContentType=0" width="1" height="1">
