DETAILED DESCRIPTION OF THE INVENTION As shown in FIGS. 1 to 3, the present invention reduces the thickness of a substrate portion 3, an antenna mounting seat 10, and an elevation angle adjusting plate portion 7 of a support base plate 1 so as to reduce the weight. On the back surface 28, a rib 29 is provided so as to protrude from the rear surface 28 in order to secure rigidity such that the antenna 35 does not bend due to the weight of the satellite broadcast receiving antenna 35.

The support base plate 1 includes a first hinge portion 5 and a second hinge portion 5.
The bending of the hinge portion 8 and the bending of the base 16 of the slide seat 6 allow the slide seat 6 to be slidably fitted into the guide groove 9 of the antenna mounting seat 10, and the slide seat 6 is connected to the antenna mounting seat 10 by the connector 36. The antenna support 37 is configured to be detachably connected.

The first hinge portion 5 and the second hinge portion 8 are provided on the front surface 11 side of the support base plate 1 (the back surface 28 shown in FIGS.
(Side). This groove 3
Reference numerals 2 and 33 denote elevation angle adjusting plate 7 and antenna mounting seat 10.
The material, the shape, the size, the thickness, and the width of the groove are selected so that the antenna can rotate repeatedly within the antenna elevation angle adjustment range and can support the satellite broadcast receiving antenna 35 at the set elevation angle.

The antenna mounting seat 10 of the antenna support 37
When a satellite broadcast receiving antenna 35 is attached to the
0), a coaxial cable passed through the coaxial cable hole 15 to the output terminal 21 protruding from the hole 22 of the antenna mounting seat 10.
Connect the bull.

The substrate portion 3, the elevation adjusting plate portion 7, and the antenna mounting seat 10 are all thin, but are reinforced by the ribs 29, so that substantial bending due to the weight of the antenna does not occur. If the bifurcated seat 2 protrudes from both sides of the substrate 3 toward the elevation adjustment plate 7, the seating of the antenna support 37 is further improved. Also, for a floor surface having unevenness,
It is preferable to use three or more protruding portions that are seated on the floor on the back surface of the device.

The second hinge portion 8 is formed with arc-shaped or nearly arc-shaped long holes 40 and 41 projecting toward the antenna mounting seat 10 in the middle thereof.
Is formed by two grooves 33, 33 communicating with the long holes 40, 41, and a seat 44 connected to the substrate 3 is obtained, so that the length of the substrate 3 in the longitudinal direction becomes longer, and the antenna support 37 Stability is further improved.

The elevation of the antenna can be adjusted by loosening the connecting member 36, bending the first hinge portion 5 and the second hinge portion 8 and bending the base portion 16 of the slide seat 6. When the antenna elevation angle is determined, the connecting member is adjusted. 36, the elevation adjustment plate 7 and the antenna mounting seat 10 are integrated.

As shown in FIG. 11, when the antenna elevation angle is small, the antenna support 37 to which the satellite broadcast receiving antenna 35 is attached has the center of gravity of the antenna closer to the front, so that the first hinge part 5 and the second hinge part are provided. Numeral 8 supports the satellite broadcast receiving antenna 35 with the curvature radii of the grooves 12 and 13 being substantially the same. Conversely, in the antenna shown in FIG. 12 in which the elevation angle of the antenna is large, the center of gravity of the antenna is located rearward, so that the width of the opening end of the first hinge portion 5 is widened and the radius of curvature of the groove 12 is large, but the second hinge portion 8 is inverted. The satellite broadcast receiving antenna 35 is supported in a state where the width of the opening end of the groove 12 is reduced and the radius of curvature of the groove deeper is reduced.
