Multi-beam shape supplementary device

Multi-beam shape supplementary device for connection to a primary or secondary communications terminal of a multi-beam shape control device for an antenna system for mobile communications, comprising:

• a site-sharing adapter in the form of a primary adapter, which is provided with a female or male connector configuration on the associated coupling terminal thereof, or in the form of a secondary adapter, which is provided with a male or female connector configuration on the associated coupling terminal thereof,
• the site-sharing adapter comprises at least two primary terminals for connecting at least two primary control apparatuses,
• the plug and/or terminal configuration or terminal occupation at the primary terminals are compatible with the terminal configuration or terminal occupation of the coupling terminal of the site-sharing adapter,
• the terminal pins or terminal sockets, provided for the bidirectional signal transmission in the site-sharing adapter, on the at least two primary terminals are connected to a terminal pin or a terminal socket, provided for the bidirectional signal transmission, of the coupling terminal so as to form a bidirectional signal transmission path,
• the bidirectional transmission path is configured in such a way that the differentiated communications signals at the at least two primary terminals are converted into frequency-modulated signals, which are present at the coupling terminal, the frequency-modulated signals present at the coupling terminal conversely being converted into differentiated communications signals which are present at the relevant terminal pin or the relevant terminal socket of an associated primary terminal.
