Control device for adjusting a different slope angle, especially of a mobile radio antenna associated with a base station, and corresponding antenna and corresponding method for modifying the slope angle

A control apparatus for setting a different depression angle, in particular for a mobile radio antenna which is part of a base station, having the following features:

• the control apparatus has control electronics,
• the control apparatus also has an electric motor,
• the control apparatus can preferably be operated by means of an appliance or command appliance,
• characterized by the following further features:
• the control apparatus is accommodated with its control electronics in a control housing which is separated or isolated from the protective cover for the mobile radio antenna, or consists of a complete unit or complete module,
• the electric motor of the control apparatus can be coupled to an operating element, which is passed out of the interior, which is covered by the protective cover of the mobile radio antenna via an operating opening or is introduced into the interior of the protective cover via this operating opening, or can be coupled to an operating element which is located under or underneath the protective cover, such that the control elements which are provided in the interior of the protective cover can be operated via this operating element in order to set a different depression beam angle.
