Antenna for reception of satellite broadcast

Abstract

An antenna for receiving a satellite broadcast can adjust orientation at higher precision than a method based on a compass and a level, without being influenced by environmental magnetic field generated by magnetic body or electromagnetic sources, can perform adjustment of orientation even before a radio wave from the satellite is not catched, can monitor the deviation during the fixation of the antenna orientation to improve the workability in adjustment of antenna orientation. The antenna for receiving a satellite broadcast has a reflector for reflecting a radio wave from a satellite on a reflecting surface for convergence and a receiving portion for receiving the radio wave reflected by the reflector. The antenna further includes a light blocking portion forming a shadow by the sun light, a scale determining a direction of the sun by the shadow formed by the light blocking portion. The light blocking portion and the scale are provided at an upper end portion of the reflector.
