である。 In recent years, reception of television broadcasts via satellite has begun to be implemented in many parts of the world. Satellite broadcasting is carried out using the SHF band and radio waves, and reflecting mirror antennas such as parabolic antennas and offset parabolic antennas are used for reception. These antennas are installed with the antenna reflection surface facing the satellite and have an elevation angle. For this reason, when it snows, snow adheres to the antenna reflecting surface, degrading antenna performance, and snow accumulation can deform and damage the reflecting mirror.
To prevent snow from accumulating on the antenna reflecting surface,
A method has been proposed in which a sheet-like bag is placed over the antenna to cover the antenna with the bag. As shown in FIG. 1, the bag 1 has its open end folded back and a cylindrical insertion hole 2 is provided on its periphery.A string 3 is passed through the insertion hole 2, and both ends of the string 3 are positioned outside the insertion hole 2. There is. FIG. 2 shows an example in which the bag 1 is attached to an offset parabolic antenna device. That is, code 4
5 is an offset parabolic reflector; 5 is a mast; A converter 8 is attached and connected directly to the primary radiator 7 . Here, the bag 1 is placed so as to accommodate the primary radiator 7, converter 8, and support fitting 6 from the reflecting surface side, and the opening of the bag 1 is made to cover the offset parabolic reflector 4 from the outer periphery to the back surface. , tie both ends of string 3. This completely prevents snow from adhering to the antenna reflecting surface during snowfall, but during fine weather in autumn or spring, the inside of bag 1 is almost completely sealed, so the temperature inside is quite low. As the temperature rises, the electronic components housed in the converter 8 become hot, their characteristics deteriorate, and they become unusable.
Therefore, in view of the above circumstances, this invention has a snow prevention effect equivalent to that of conventional ones, and in addition, it has a snow prevention function that prevents the electronic components housed in the converter from becoming hot when the temperature rises in good weather. It was developed for the purpose of providing a bag body, and the converter protrudes outward from an insertion hole provided at the bottom of the bag.
以下、本考案を第3〜8図に示す具体的な実施

到達する。 FIG. 4 shows an example in which the bag 9 is attached to an offset parabolic antenna device. Reference numeral 15 is an offset parabolic reflector, 16 is a mast, and a primary radiator 18 is mounted on the reflective surface side at the tip of a support fitting 17 extending forward from the back surface of the offset parabolic reflector 15.
is installed so that it is located at the focal point of the offset parabolic reflector 15, and a fifth
The converter 12 is connected to the converter 12 by interposing a disk-shaped overhanging plate 19 having a larger diameter than the primary radiator 18 as shown in the figure. This overhanging plate 19 is made up of two semicircular members, and since the connection part with the primary radiator 18 of the converter 12 is formed in a square shape, a square hole 20 is bored in the center to allow the connection part to be inserted therethrough. . Here, the bag body 9 is covered from the reflective surface side, the converter 12 is protruded outward from the insertion hole 13, the primary radiator 18 and the supporting metal fittings are accommodated, and the opening is covered from the outer periphery to the back surface of the offset parabolic reflector 15. ,
Tie and secure the string 11. The bottom of the sheet bag 9 is extended and supported in a predetermined circular shape by the overhang plate 19, so even if snow falls on the bag 9, the bag 9 will not be brought close to the primary radiator 18, and the antenna reflection surface will be The reflected radio waves reliably reach the primary radiator 18.

低下させることはない。 Next, an example in which the bag body 9 is attached to the upper part of the outer circumferential flange 21 of the offset parabolic reflector 15 with the spacer 22 interposed therein will be explained with reference to FIGS. 6 to 8. Note that other parts are the same as those in the previous embodiment. The spacing member 22 is an arc-shaped member along the outer periphery of the offset parabolic reflector 15, and has a V-shaped cross section, and is a mounting groove into which the outer flange 21 facing rearward from the outer periphery of the offset parabolic reflector 15 is fitted. 23 and an eaves piece 25. The mounting piece 24 of this spacing member 22 is attached to the outer peripheral flange 21 on the upper part of the offset parabolic reflector 15, and then the bag body 9 is covered in the same manner as described above. Then, since the upper outer peripheral edge of the offset parabolic reflector 15 is covered with the bag 9 with the spacing material 22 interposed, and the bag 9 is provided at a predetermined distance from the antenna reflecting surface, snow will not accumulate on the bag 9. However, the antenna performance is not degraded due to the deflection of the bag body 9.
