Disclosed is a phase shifter arrangement for an antenna, such as a cellular antenna, that has a simplified drive mechanism. The phase shifter arrangement has two phase shifters, each with two wiper arms that are coupled at one end to a single drive shaft. Each of the wiper arms have a pivot access that may be located at or near its center such that as the drive shaft translates, it mechanically engages both wiper arms, causing them to rotate around their respective pivot axes. Certain antenna arrangements have several array faces. For example, the antenna may have three array faces, each spaced at 120 degrees of azimuth. The drive shafts for each of these array faces may operate independently to function as a multisector antenna, or they may be driven in unison to function as an omnidirectional antenna.
