Antenna rotator АПУ-М

Antenna rotator for several directions of transceiving (communication) with remote alignment in azimuth and elevation

Multidirectional recieve/transmit (communication) antenna rotator with remote azimuth and elevation adjustment.

Multidirectional recieve/transmit (communication) antenna rotator with remote azimuth and elevation adjustment.


Antenna rotator АПУ-М is designed for:

branching and repeater field radio-relay stations of direct visibility with the prompt re-targeting of the communication directions and the prompt azimuth and elevation adjustment using the correspondent's radio signal

  • transportable cellular base stations;

  • telecentres with the prompt reception of reportage outside information;

  • construction and operation of radio complexes in remote areas.

Patent of the Russian Federation No. 2319260 dated March 10, 2008 (priority of the invention dates April 05, 2006) was obtained for the antenna rotator

Distinctive features:

  • original implementation of the supporting rotator, which minimizes the twisting of the structure;

  • easy assembly of the antenna rotator during the installation of equipment;

  • possibility of transmitting up to 2 radio channels in one direction of communication;

  • remote adjustment in azimuth and elevation angle with two-speed travel in azimuth within ± 160О, position memory, three-level protection at limit turn-aways of antenna devices;

  • possibility of a considerable distance –up to 200 m – from the hardware;

  • wide range of additional options for the antenna rotator equipment;

  • low weight of the equipment.
