Techniques for antenna positioning system having a drive element shared by multiple antennas for positioning about a positioning degree of freedom are described. In some examples, each antenna can be coupled with a rotating spindle, with each antenna spindle being coupled with the shared drive element. By driving a shared drive element, each of the antenna spindles in the system can be rotated via the associated coupling. In some examples, such a coupling may include link arms with an adjustable length to reduce backlash or to apply a preload to the system. In some examples, such a coupling may be configured to position multiple antennas over different orientation ranges in response to the drive element driving over an actuation range, which may include one antenna being idled or otherwise maintained at an orientation while another antenna is driven, or may include different antennas being driven according to different actuation ratios.
