MOBILE ANTENNA ARRANGEMENT Russian patent published in 2005 - IPC

FIELD: lifting-tower mounted mobile antenna arrangements.

SUBSTANCE: lifting tower of antenna has levers with relatively hinged joints that form top and bottom sections for entry of top section into bottom one in folding. Top section mounts supporting platform for antenna positioning device. Supporting platform is hinged for turning relative to horizontal axis disposed perpendicular to turn plane of lifting tower. Antenna positioning device is mounted on intermediate platform hinged to supporting platform for turning relative to other horizontal axis. Axes of turn of mentioned platforms are disposed in relatively perpendicular planes. Intermediate platform is designed for self-setting in desired position relative to supporting platform during antenna folding. Antenna arrangement is equipped with platform servo drives and intermediate-platform level balancing sensors.

EFFECT: reduced space requirement, enhanced speed of setting-up and packing procedures in dislocation.
