Windproof support frame for offset paraboloidal reflector antenna - rotates on oblique axis between azimuthal vertical and direction of waves reflected from surface of paraboloid

摘要

The V-shaped support (4), for the reflector (2) and an arm (23) on which high-frequency equipment (26) is positioned at the focus (25), rotates about an axis (29) at an acute angle (alpha) to the vertical azimuthal axis (12). The direction of radiation (28) from the reflector (2) intersects the rotational axis (29) at another acute angle (beta). Pref. the support (4) has a wedge-shaped portion (14) and is upheld by a pin through a bearing (30), with an annular carrier (16) on two supporting wheelsets (33) on a relatively flat base (3). ADVANTAGE - The frame requires less material and is less susceptible to gale damage.
