These are identical when it comes to the antenna. The measurement point is the pad of C15, which is where to antenna starts.</p> <p><a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/PCA10028-SWR.WMF">PCA10028 SWR.WMF</a></p> <p><a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/PCA10028-Smith.WMF">PCA10028 Smith.WMF</a></p> <p>-Anders</p><div style="clear:both;"></div>
