The RET adjuster includes a drive assembly with a rotatable drive member operatively connected to a phase shifter assembly such that rotation of the drive member adjusts the phase shifter assembly. A first connector is coupled to the drive member where the first connector occupies a rest position when the drive member is at rest. A drive system has a second connector occupying a rest position when the drive system is at rest where the second connector is releasably engageable with the first connector such that actuation of the drive system rotates the drive member. A mechanical calibration system locates the second connector at the second rest position.

Multi-RET actuators include a plurality of shafts that have respective axially-drivable members mounted thereon. Each of axially-drivable member is mechanically linked to a respective one of a plurality of phase shifters. The multi-RET actuator further includes a motor having a drive shaft and a gear system that is configured to selectively couple the motor to the respective shafts. The gear system is configured so that rotation of the drive shaft in a first direction creates a mechanical linkage between the motor and a first of the shafts, and rotation of the drive shaft in a second direction that is opposite the first direction rotates the first of the shafts.

Actuators for controlling multiple phase shifters of remote electronic downtilt base station antennas

A mechanical tilt mounting system for a base station antenna includes a fixed pivot that connects the antenna to a support structure. The antenna is rotatable about the fixed pivot. An adjustable control arm has a first end connected to the antenna and a second end connected to the support structure. Extension and contraction of the adjustable arm rotates the antenna about the fixed pivot to change the angle of inclination of the antenna.

Mechanical tilt mounting system for a base station antenna

Base station antennas include a RET actuator, a plurality of phase shifters and a plurality of mechanical linkages, where each mechanical linkage is connected between the RET actuator and a respective one or more of the phase shifters. The RET actuator includes a drive element, a rotatable element and a mechanical linkage selection system that is configured to move a selected one of the mechanical linkages into engagement with the drive element. The drive element is configured to move linearly in response to rotation of the rotatable element to move the selected one of the mechanical linkages.

A battery protection mechanism is provided within an electronic device. A door has a latch which fits into a latch retention-release mechanism in the base of the device. A spring under tension within a retention-release mechanism presses against the latch when the device is in a closed configuration. A foot attached to a button in the base of the device urges the door out of position upon depression or activation of the button.
