摘要
A first mechanical linkage is connected between a RET actuator and a first phase shifter. A second mechanical linkage is connected between the RET actuator and a second phase shifter. The RET actuator includes a rotary drive element operably coupled to at least one drive gear for moving the at least one drive gear in a first rotary direction and a second rotary direction. A first drive system is connected to the first mechanical linkage and a second drive system is connected to the second mechanical linkage. The first drive system has a first driven gear and the second drive system has a second driven gear where the first driven gear and the second driven gear are coaxially located relative to one another. An index system selectively couples the at least a one drive gear to one of the first driven gear and the second driven gear.
