A method for testing the transmission and reflection properties of an automotive radome body is described. An automotive radome body is placed at an installation location. A first signal is sent via at least one transmission antenna of an antenna system facing a first side of the radome body wherein the reflected part of the first signal is received by several receiving antennas of the antenna system facing the first side in order to determine the reflection properties of the radome body. A second signal is sent via a remote transmission antenna facing a second side of the radome body being opposite to the first side wherein the transmitted part of the second signal is received by the several receiving antennas of the antenna system in order to determine the transmission properties of the radome body. Further, an apparatus is described.
