This specification discloses an apparatus and method for supporting and moving an antenna load when tracking a satellite in a synchronous orbit. The apparatus includes three elongated supports all of which are attached to the antenna with couplings having a two degree of freedom of movement and two of which supports are attached to the ground with couplings having a two degree of freedom of movement. A stabilizing member coupled between the two supports having a two degree of movement connection with the ground rigidifies the support apparatus. Adjusting the longitudinal length of the elongated supporting members permits the antenna to be simply and effectively positioned over a wide angular range.

A support adjustment apparatus for supporting and moving an antenna load with respect to a base member, said antenna load being symmetric and having a fixed point of rotation off the axis of symmetry of said antenna load, said support adjustment apparatus comprising: a first suspension point, a second suspension point and a third suspension point associated with the load for permitting movement of the load with respect to said support adjustment apparatus, said first, second and third suspension points permitting rotation about two axes so that the load has two degrees of freedom of movement with respect to each of said suspension points; a fourth suspension point, a fifth suspension point and a sixth suspension point associated with the base member so that there is no relative movement of the base member with respect to said fourth suspension point, and said fifth and sixth suspension points permitting two degrees of freedom of movement with respect to the base member; a first connecting means for connecting said first and fourth suspension points; a second connecting means for connecting said second and fifth suspension points; a fourth connecting means for connecting said third and fifth suspension points so that the load can move relative to the base member about two axes, a first axis being defined by said first and fifth suspension points and a second axis being defined by said first and third suspension points, and said first suspension point being positioned at a distance from the edge of the load less than one half the width of the load and said first connecting means having a length less than one half the width of said load thereby providing that the bending load applied to said support adjustment apparatus is applied to a member having a length less than one-half the width of said load and permitting said axis of symmetry to achieve both a horizontal and a vertical orientation with respect to the base member.
