METHOD FOR ANTENNA REFLECTOR ERECTION ON AN AZIMUTH BEARING ROTARY ARRANGEMENT Russian patent published in 1994 - IPC

FIELD: antenna technology. SUBSTANCE: method for erection of reflector of antenna 1 on an azimuth bearing rotary arrangement 2 includes steps of tilting azimuth bearing rotary arrangement 2 in a vertical plane toward erection zone 15 for an angle ϕ; rotation of reflector central hub 3 in the relation to the elevation axis; securing of frame members on central hub 3 and to each other. The frame members are secured in turn, with reflector central hub 3 rotated in the relation to the azimuth axis. As this takes place, central hub 3 is rotated at an angle a to the elevation angle axis so as its axial misalignment h in the relation to erection zone floor is minimal. After erection, the antenna reflector is installed into operational position by means of tilt linear drive 11. EFFECT: reduced erection time; increased serviceability; reduced erection zone. 2 dwg
