PURPOSE:To receive satellite television broadcasting inside a room by reducing the transmission or reflection loss of the wave of satellite television broadcasting of 12GHz band by using a plate consisting of an insulator such as an acryle plate having a low dielectric constant, etc., instead of glass. CONSTITUTION:Satellite broadcasting is received by using the acryle plate 1 as a translucent insulating plate having low dielectric constant instead of glass. The wave arriving in a direction of A passes a window consisting of the acryle plate 1, then, is received by a parabolic antenna 5. The acryle plate 1 is mounted on an aluminum sash 3 via a gasket 2 similarly as the glass. Another insulating material, if it is one having low dielectric constant, for example, polycarbonate whose relative dielectric constant is around three, or polypropylene whose relative dielectric constant is around two, can be used instead of an acryle plate. |
