  • the embodiment also has three cutting and / or Kupplüngsstellen 25, at least when considering the three transmission and / or adjusting devices 73, wherein based on the output line 125 thereby three coupling positions 25 'are defined or to purposefully one of the Phasenschieber- To operate assembly or other adjustment of the antenna.
  • Such output strands can also be formed several times on the multi-RET unit, whereby the number of selectively controllable phase shifter can be increased.
  • a switchable, in particular electromechanically switchable clutch or adjusting be integrated in the transmission, as well as a corresponding drive control with one or more motors to perform the adjustment.
  • At least one servomotor may be provided.
  • the servomotor would serve, for example, to adjust the output shaft 123 with the associated actuating and actuating elements 71, 71 "so that this actuating and actuating element 71, 71" is moved into a desired position, in which a clutch with a corresponding, in the side embodiment gear-shaped transmission and / or adjusting device 73 is added.
  • the axial adjustment could be carried out via the drive motor and the rotary motion could be brought about via the actuating or coupling motor to finally bring about the coupling with the corresponding setting and actuating device 71, 71 "
  • the drive unit and the setting unit wherein the one motor, the axial adjustment and the adjustment of the phase other motor accomplished the twisting movement, ie rotation of the shaft.
  • the number of cutting and / or coupling points is greater than the number of drive means, that is, the common drive means, wherein, as explained, for example, a drive means may also include one or more additional actuator or coupling drives or motors, to make a drive connection between the corresponding actuators can.
  • a drive means may also include one or more additional actuator or coupling drives or motors, to make a drive connection between the corresponding actuators can.
  • coupling means 77 are actuated and adjusted accordingly with the associated clutch actuators 79, wherein after a prepared coupling connection (by means of a servomotor) then the adjustment z. B. the connected phase shifter can be performed by means of the drive means.
  • phase shifters in the antenna can be controlled, similar to the structure described using flexible shafts or axles. which are positioned at different positions.
  • the bridging between the gear assembly or the multi-gear housing M-RET-G and the corresponding components to be controlled as the phase shifters be positioned at various points.
  • additional control devices can run from the M-RET unit into the antenna interior, via which electromechanical actuators located there can be actuated, so that the power flow in the drive trains can be separated or closed.
  • coupling devices which are arranged directly on the shaft or the output line 123 of the gear arrangement or also on the phase shifters themselves or in the vicinity of the phase shifters or other adjustable subassemblies, as is particularly apparent from the exemplary embodiment FIG. 5 (or FIG. 6 ).
  • an electric motor is used as a drive device.
  • all other controllable drive devices are basically considered.
  • the multi-beam shaping device M-RET can also be provided with at least one further communication interface, for example in the sense of daisy-chain cabling to connect another multi-RET unit to control other antenna devices.
  • the control of a plurality of multi-beam shaping devices interconnected therewith can take place via a communication line 11, 11 '.
  • the described multi-gear can be used in all antenna designs, in single-band antennas as well as in dual-band or multi-band antennas.
  • the invention can be used with radiator antenna arrays arranged in one or more columns.
  • the radiator devices can be singly or multiply polarized. There are no restrictions in any direction.
