System.For example, if linear array 120 includes double polarization radiating element 130, usually at each of two cross polarizations place
The RF signal of transmitting applies identical phase change.In which case it is possible to use single mechanical linkage 226 controls two
The position of wiper printed circuit board 220,220a on phase shifter 202,202a.In other cases, two phase shifters 202,
Wiper printed circuit board 220, the 220a of 202a may be coupled to different pitman shafts 228.
As described above, by sending to antenna 100 so that electromechanical actuator adjusts the control of the setting on electromechanical phase shifter 150
Signal processed, can be controlled from remote location RET antenna as such as antenna 100 various physics and/or electrical setting (including
The elevation angle).In general, being mentioned for each phase shifter 150 (or being a pair of of phase shifter 150 associated with cross polarization radiations element 130)
For individual actuator.The more RET actuators that can be used for controlling multiple and different phase shifters have been proposed recently.
Different phase shifters can have different design and/or size, therefore be connected to the mechanical linkage of different phase shifters
Maximum length of stroke may need to be different.Particularly, if mechanical linkage movement has been more than to design for particular phase shifter
Defined maximum length of stroke, then phase shifter is likely to be broken.Therefore, the range for adjusting RET actuator 300 is associated to limit
Mechanical linkage stroke can be it is beneficial.
