Abstract
A base station comprises a reflector, remote electronic tilt actuator, an array of radiating elements, the radiating elements mounted to extend forwardly from the reflector, and a first metal tuning element that is at least partly positioned in front of the reflector. The first metal tuning element is configured to move when a remote electronic downtilt setting for the array of radiating elements is changed.
Claims27
A base station antenna, comprising:
- a reflector;
- remote electronic tilt (“RET”) actuator;
- an array of radiating elements, the radiating elements mounted to extend forwardly from the reflector;
- and
- a first metal tuning element that is at least partly positioned in front of the reflector,
- wherein the first metal tuning element is configured to move when a remote electronic downtilt setting for the array of radiating elements is changed.
The base station antenna of claim 24, wherein the first metal tuning element is mounted on an element of the mechanical linkage.
(canceled)
The base station antenna of claim 24, wherein movement of the element of the mechanical linkage from a first position to a second position is configured to change a position of the first metal tuning element.
