ABSTRACT:
A rotator comprises a gear housing which has a lower attachment for fitting the housing to the top of a mast, and which has extending therefrom a tube which can be rotated about its longitudinal axis relative to the gear housing by means of a gear therein, this tube being intended to carry a top sleeve, which in turn is intended to carry an aerial. The invention is characterized in that an upper attachment (3) is mounted on the outer end of the tube (5); in that the upper attachment (3) includes a lower part (6) which is connected firmly to the tube (5) and an upper part (4) which is hinged to the lower part (6); in that the tube (5) has located therewithin a rod (10) or like element which can be moved in the direction of the tube axis and the upper end of which rod (10) is attached to the upper part (7) of the upper attachment (3), such that when the rod (10) is moved axially the angle defined by the two attachment parts (6, 7) with said longitudinal axis is changed; and in that the gear housing has provided therein activating means (18, 19, 26, 27) for displacing the rod (10) axially relative to the gear housing (1), therewith enabling a top sleeve (4) attached to the upper part (7) of the upper attachment (3) to be brought to a pre-determined angle with the tube (5) and enabling this angle to be maintained during rotation of the tube about its longitudinal axis.
