Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to the mounting structure of a flat antenna for receiving satellite broadcasting and satellite communications. It is.

0002

[Conventional technology]

Conventionally, parabolic antennas and flat antennas that receive satellite broadcasting and satellite communications have not been publicly available. It has become knowledge. These antennas are oriented so that the receiving surface faces the satellite. It is attached to a pole or wall at an angle of It was installed on the roof or on the balcony.

0003

[Problem that the idea aims to solve]

In general, parabolic antennas are bowl-shaped as shown in Figure 8, so they are oriented horizontally. It is made eccentric to prevent rain and snow from accumulating on the bottom. When viewed from the front, it has an elliptical shape and has a larger area than a circular planar antenna. Therefore, the influence of wind and snow becomes greater, and the structure of the supporting member is more sturdy than that of a flat antenna. It was. For example, as shown in FIGS. 8 and 9, the support point of the parabolic antenna 5 The diameter D1 of the pole was made larger than the diameter D2 of the support pole of the planar antenna 6. be. Therefore, parabolic antennas support VHF antennas and UHF antennas. It is not possible to mount it on a pole, and a flat antenna cannot be mounted. It was. However, the mounting bracket 7 of the flat antenna was placed in the center of the back side. If you install it halfway on the support pole, the top end of the planar antenna will hit the support pole. , the resistance increases above the VHF antenna, so attach it to the same support pole. It was not possible. However, if you attach the extension bracket to the flat antenna mounting bracket, It was common practice to attach it to the base of a support pole.

0004

[Means to solve the problem]

In order to solve these problems, the present invention has been developed by attaching a planar antenna to a support pole or When the antenna is fixed to a wall, a mounting bracket is installed at the top of the back of the flat antenna. Make sure that the extension of the mounting part of the mounting bracket to the support pole does not interfere with the top end of the flat antenna. The mounting portion is disposed at a certain position.

[0005]

[Effect]

An optional part of the support pole 1 is sandwiched between the flat antenna mounting bracket 14 and the fixing bolt 17. the mounting bracket 13 fixed to the top of the back surface of the planar antenna 2. Even when fitted to the mounting bracket 14, the top end of the planar antenna and support pole 1 no longer come into contact with each other. , even if you adjust the angle of the flat antenna, it will not hit, and it can be adjusted over a wide range. be. Then, the installation is completed by fixing the adjustment bolt 16.

【Example】

The problems to be solved by this invention and the means for solving them are as described above. The configuration of the embodiment shown in the accompanying drawings will be explained. Figure 1 shows the support pole of the bar antenna. Figure 2 is a perspective view of the flat antenna attached to the Figure 3 is a side view, and Figure 4 is a side view of the mounting bracket fixed to the flat antenna side. Figure 5 is a side view, Figure 6 is a front view of the mounting bracket fixed to the pole side, Figure 7 is a top view. is also a side view. Although the planar antenna is circular in this example, it may be rectangular, etc. The shape is not limited, and a satellite broadcast receiving antenna will be described. Planar antenna 2 The front side is the receiving surface, the power feeding part is provided in the center, and the converter is fixed to the back side. connected to the controller 10. The converter 10 converts circularly polarized waves into linearly polarized waves. Amplification is performed, frequency conversion is performed, and the signal is transmitted indoors via a coaxial cable from output terminal 11. Radio waves are sent to the tuner.

[0007] A mounting bracket according to the present invention is installed above the converter 10, that is, at the top of the back surface of the planar antenna 2. The tools are arranged. The mounting bracket is a mounting bracket 1 fixed to the planar antenna 2. 3 and a mounting bracket 14 fixed to the support pole 1, the mounting bracket 13 is shown in FIG. As shown in FIG. 5, the rear mounting surface 13 is configured to have a U-shape in plan view and a substantially fan-shape in side view. An inverted U-shaped cutout 13b is provided downward from the center a, and the converter is inserted into the cutout 13b. -10 can be inserted, and insert holes 13c and 13 for mounting screws on both sides of the notch 13b. c... is opened so that it can be fixed to the planar antenna 2. Also, the side plate Engagement bolt 15 screwed into the mounting bracket 14 on the support pole side on the upper part of 13d and 13d Hook parts 13e and 13e are opened for hanging on the side plates 13d and 13d below. Arc-shaped elongated holes 13f and 13f are opened in the upper part of the hook part 13e. and a scale is engraved on the top.

[0008] As shown in FIGS. 6 and 7, the mounting bracket 14 on the support pole side is U-shaped in plan view and has a side surface. The side plate 14 is configured to have a trapezoidal shape and can be fitted inside the mounting bracket 13. Open bolt holes 14b and 14b at the upper end of a and 14a, and screw the engagement bolt 15 therein. so that the hook portions 13e, 13e can be engaged, and the side plates 14a, the lower part of the 14a Adjust by opening bolt holes 14c and 14c at the ends and aligning them with the long holes 13f and 13f. By screwing in the alignment bolts 16 and fixing the mounting bracket 13, the planar antenna 2 The angle is adjustable. In addition, there are convex portions 1 above and below the center of the front mounting surface 14d. 4e and 14e are provided for reinforcement, and recesses 14f and 14f... are provided above and below them. to enable positioning of support pole 1, and bolt holes 14g/1 on both sides. 4g... are opened and U-shaped fixing bolts 17, 17 that match the diameter of the support pole 1 Place the support pole 1 inside the mounting bracket 14 and tighten the fixing bolt. It is made so that it can be sandwiched between 17 and 17 and fixed with a nut. In addition, the bolt hole 1 4g/14g...Fix to the wall by inserting the fixing bolt from the inside is also possible.

[0009] The distance D3 between the inner ends of the bolt holes 14g and 14g in the width direction is the maximum distance of the support pole 1. The supporting pole 1 has a large diameter, and the width of the length D3 from the inner surface of the mounting surface 14d shown in FIG. This is the maximum width occupied by the support pole and becomes the mounting part, and this invention extends the support pole mounting part upward. The antenna is arranged so that the top and the top end of the planar antenna 2 do not interfere with each other. With this configuration, the mounting bracket 13 is fixed to the top of the planar antenna 2, Attach the bolt to the specified position of the support pole 1 with the mounting bracket 14 and fixing bolts 17. Fix it with a bolt, screw the engagement bolt 15 into the bolt hole 14b, 14b, and install. The hook portions 13e and 13e of the metal fitting 13 are engaged to fit into the mounting metal fitting 14, and the elongated hole 13 is fitted. Align f/13f with bolt holes 14c/14c, screw in adjustment bolt 16, and Tighten and fix the adjustment bolt 16 in the position where the surface antenna 2 faces the satellite, and the VHF Attach the support pole 1 to the same support pole 1 to which the antenna 4 and UHF antenna 3 are attached. A flat antenna can be installed.

[Effect of the idea]

With the above configuration, the present invention provides the following effects. That is, Since the mounting bracket is placed on the top of the flat antenna, it can be used to support the parabolic antenna. It can be used to attach existing VHF or UHF antennas without the need for new, heavy-duty support members. so that it can be attached to the same support pole that the antenna is attached to. Also, make sure that the top of the planar antenna and the extension of the pole mounting part of the mounting bracket do not interfere. However, since the rotation fulcrum is located at the top of the planar antenna, the range of angle adjustment is limited. It is wider and can be installed in any position such as a wall or balcony, making it possible to install it anywhere. The range of choices has become wider, and it has become possible to install them with aesthetics in mind.
