%X Hidden photon and axion-like dark matter may be detected using spherical reflective surfaces such as dish antenna setups converting some of the dark matter particles into photons and concentrating them on a detector. These setups may be used to perform directional searches measuring the dark matter momentum distribution. We briefly review the photon distribution one expects to detect with such an antenna and directional resolution in ray approximation. Furthermore we consider the regime m<sub>DM</sub>  <~(R<sub>sp</sub> v<sub>DM</sub>)<sup>−1</sup> where this approximation does not hold anymore due to photon wavelengths exceeding the expected distribution widths. We discuss how this affects the expected distributions and experimental implications.
