An improved multi-beam shape supplementary device, more particularly for mobile radio antenna systems, is distinguished, inter alia, by the following features: the multi-beam shape supplementary device comprises a site sharing adapter (A) in the form of a primary adapter (PA), the site sharing adapter (A) has at least two primary connections (A1, A2, A3) for connecting at least two primary control units, the plug and/or connection configuration or connection assignment at the primary connections (A1, A2, A3) are connection-compatible with the connections on the coupling connection side (KoAn) of the site sharing adapter (A), the pin or socket connections (14; 3, 5) provided for the bidirectional signal transmission in the site sharing adapter (A) are connected to a connection pin or a connection socket (3)-provided for the bidirectional signal transmission-of the coupling connection (KoAn) with the formation of a bidirectional signal transmission path, and the bidirectional transmission path is designed such that the differential communication signals present at the at least two primary connections (A1, A2, A3) are converted into frequency-modulated signals. |
