Tidal disruption events (TDEs) are rare, multi-wavelength transients that allow astronomers to probe otherwise quiescent supermassive black holes (SMBHs). Only a fraction of TDEs exhibit luminous radio emission, with fewer still appearing consistent with a transient, relativistic jet. Despite their scarcity, the TDEs discovered thus far have been transformational in understanding of jetted transients and supermassive black hole accretion. In this talk, I will present our comprehensive radio analysis of the jetted TDE AT2022cmc. I will demonstrate how our dense radio and sub-mm coverage allowed us to constrain both the large-scale geometry and microphysics of transient ejecta. From there, I will use these results to demonstrate how our observations thus far can be used to find off-axis jetted TDEs and explore what this can mean for transient accretion onto SMBHs.
