PURPOSE:To fix a plane antenna without dislocation and to receive a radio wave with a sufficient intensity by fixing a casing for containing the plane antenna to a bolt fixed on a roof. CONSTITUTION:The casing 3 containing a pair of plane antennas 2 is constituted of a body 11 and a cover 12, both of which are made of a synthetic resin with a high radio wave transmissivity, and oblong holes 4 are formed on four bottom corners of the body 11 of the casing 3 along one side. The elevation and azimuth angles of the antenna 2 are adjusted by an elevation angle adjuster 22 and an azimuth angle adjuster 23, respectively. A fitting 5a provided with a bolt upward and protrusively is fixed on a roof tile 1a fitting the casing 3. The fitting piece 16 of the fitting 5a is fixed on a roof base, and the fitting 5a is formed with an upright pierce 17, a lateral plate 18 and a bolt fixing piece 20. Then the bolt 6 is inserted into the oblong hole 4 of the casing 3, and a nut is screwed at the tip of the bolt 6. And the antenna 2 is fixed without dislocation, whereby a radio wave is received with a sufficient intensity.
