FIELD: physics. ^ SUBSTANCE: invention is related to the filed of radio engineering. Device contains basis, antenna curtain and mechanism of rotation with two crank mechanisms installed on both sides of antenna curtain. Every crank is hingedly fixed, with its one end, on antenna curtain, and with the other one, on the basis. Device also includes slider installed on basis and linear drive hingedly fixed on the basis and on antenna curtain. The first holder is installed on basis so that the holder can interact with antenna curtain. Device is equipped with the second holders, each installed on appropriate crank to interact with antenna curtain. Cranks may be equipped with link. ^ EFFECT: reduction of linear drive dimensions and its travel. ^ 2 cl, 5 dwg |
