Remote electronic tilt base station antennas having adjustable ret linkages

A base station antenna, comprising:

• a remote electronic tilt (“RET”) actuator;
• a phase shifter having a moveable element;
• and
• a mechanical linkage extending between the RET actuator and the phase shifter, the mechanical linkage including a first RET rod, a second RET rod and a multi-piece RET linkage that includes a first piece that is mounted on the first RET rod, a second piece that is mounted on the second RET rod, and a third piece that is directly connected to the first piece, wherein the dimensions of the third piece are selected based at least in part on a distance between the first RET rod and the second RET rod in at least one of a width direction and a depth direction of the base station antenna.

A base station antenna, comprising:

• a remote electronic tilt (“RET”) actuator;
• a phase shifter having a moveable element;
• and
• a mechanical linkage extending between the RET actuator and the phase shifter, the mechanical linkage including a first RET rod, a second RET rod and a multi-piece RET linkage that includes a first piece that is mounted on the first RET rod, and a second piece that is mounted on the second RET rod,
• wherein the mechanical linkage further comprises a connecting member that couples to the first and second pieces and is provided in a plurality of different width and/or depth dimensions to accommodate different distances between the first RET rod and the second RET rod for different base station antenna configurations, wherein the connecting member is configured to directly connect to the first piece.
