The present invention provides an apparatus for erecting a mast, comprising: a first support that is supported on a base; an intermediate post that is pivotable relative to the first support at a first pivot, the first pivot being located at or near a first end of the intermediate support; the mast being pivotably supported by the intermediate post at a second pivot, the second pivot being located in a lower or intermediate portion of the mast when the mast is in a substantially upright position. The present invention also provides an emitter assembly, comprising one or more emitter arms which extend from a main arm, each of the one or more emitter arms having at least a portion having a cross section which has a major axis and a minor axis, the major axis lying in a horizontal plane in use and the minor axis being in a vertical plane in use. The present invention further provides an ionization device or installations, comprising an emitter assembly as described above; a mast which supports the emitter assembly; and a raising apparatus which raises the mast to an upright position in articulated stages, the raising apparatus being an apparatus as described in the paragraphs above. The present invention further provides a method of erecting an ionisation device which includes an emitter array supported by a mast, comprising: fixing a first support on a base or the ground; raising an intermediate support so that it pivots about a first pivot connection with the first support, until the intermediate support is in a substantially upright position; pivoting the mast about a second pivot connection connecting the intermediate support and the mast.
