An apparatus including a dipole antenna, configured for operation with a first polarization, the dipole antenna including a feed; and a pair of conductive elements fed by the feed, wherein the pair of conductive elements are grounded, and extend in parallel on opposing sides of the feed and then diverge.

Dipole antenna

Systems and related methods for reducing passive intermodulation (PIM) include a combination of an antenna control unit (ACU) and a remote electrical tilt (RET) system. The ACU may be used to generate rotational motion of an output drive shaft in response to an input tilt control signal. The RET system couples to the output drive shaft of the ACU and may be used to convert the rotational motion into translational motion for modifying a phase shift of an antenna beam. PIM may be substantially eliminated by providing electrical isolation between the ACU and RET system in the form of a non-conductive connector that engages the draft shaft of the ACU.
