To date, only four short-duration GRBs have detected radio counterparts \cite{Fong2015} compared to many dozen radio counterparts to long-duration GRBs \cite{Chandra_2012}.  This is almost certainly the result of the lower circumburst densities in the environments of short-duration GRBs, as the radio emission is extremely sensitive to circumburst density \cite{Sari1998}.  Figure 11 displays the X-ray, optical, and radio light curves of all short GRBs in the Swift era, again highlighting the relative paucity of radio detections.
