Abstract
The present disclosure relates to a switchable transmission mechanism for a base station antenna. The switchable transmission mechanism includes a plurality of axially drivable members, each of which is mounted on a corresponding one of a plurality of transmission rods arranged in parallel and is configured to be connected with a corresponding one of a plurality of phase shifters in the base station antenna; a transmission unit including a first gear assembly and a second gear assembly transmissibly connected to the first gear assembly, where the second gear assembly is engageable with or dis-engageable from any one of the transmission rods via a rod adapter that is movable between an engaged position and a disengaged position along an axial direction; and a switch unit configured to move the second gear assembly along a lateral direction perpendicular to the axial direction when the second gear assembly is disengaged from the transmission rod, so that the switchable transmission mechanism can selectively drive any one of the transmission rods.
