Directional mount for telecommunication antenna - has antenna reflector frame mounted on double articulated joint and on spindle to give movement about three axes

摘要

The directional mounting for an antenna is used for satellite telecommunicator system. The construction provides uniform flexible deflection of the antenna reflector. The mounting has a frame (2) onto which is mounted the reflector dish (1). It has a spindle (28) which carries the radial supports (29) for the reflector. The frame (2) is carried at its apex (3) by a triangular structure. The support structure has a triangular base (10) resting on three concrete bases (8, 8a, 8b). At the top of the triangle (11, 12), is a base plate (13) onto which is fitted a double articulated joint (14). This joint (14) allows the aerial to pivot about two axes (XX, YY) in addition to pivoting about the reflector axis (ZZ). Two jacks (31) and a motor drive rotate the aerial.
