Generally, a plurality of Yagi antennas are stacked to improve their directivity and gain, and to obtain desired performance. In this case, the number of elements, length, and spacing of the Yagi antennas to be stacked usually change depending on the frequency used and the required performance (directivity, gain). Furthermore, the stacked antennas are attached to supports of various thicknesses depending on their size, weight, etc. For example, in the case of a large size, it is attached to a special column called a panzer mast, which has a diameter of 10 cm or more. In the past, since such antennas were often used for communication purposes, all the mounting fittings were dedicated and their dimensions were fixed. In other words, the frequency to be used is determined,
Once the Yagi antennas to be stacked were determined, it was common practice to design and manufacture the dimensions of the mounting brackets to match the spacing and length of the antennas. In addition, it was common to design and manufacture the mounting bracket to the support by determining the thickness of the mounting support each time, taking into consideration the weight, wind speed, etc. of the Yagi antenna, including the mounting bracket. However, in recent years, with the diversification of information, the number of frequencies used has increased further, and the required performance has also become more specialized, and the number of types has increased from low to high. Therefore, the conventional mounting brackets mentioned above are of the so-called fixed type, which are designed and manufactured on a case-by-case basis depending on the frequency and performance required by the user. Because they were rarely manufactured (used) repeatedly, it was not possible to keep them in stock, and their prices were extremely high. That is, the conventional mounting brackets of this type are completely lacking in mass productivity, and because they are of a fixed type, it is not possible to finely adjust the stacking interval of the antennas. Furthermore, the dimensions of the mounting bracket for supporting and fixing the antenna are extremely long, sometimes reaching 1.5 m or more, especially when the operating frequency is low and high gain is required. Therefore, for example, there were serious problems in terms of distortion during plating and welding, and workability during manufacturing, transportation, and on-site assembly was extremely poor. This idea was made in view of the above circumstances,
The purpose is to provide an antenna mounting bracket with a simple structure, an extremely wide range of application, and improved workability. This invention consists of, for example, three extendable rods arranged in an H-shape, and by adjusting the length of each rod, the antennas to be stacked can be adjusted to the length of the rods. It is supported and fixed according to the interval. In addition, there is a strut mounting bracket that allows stacked antennas to be attached to struts of various lengths depending on their weight and wind speed, and a special strip-shaped mounting member that can be attached to a relatively thin pipe-shaped strut such as a panzer mast. is provided at the joint of the H-shaped bar material, so that it can be attached to a column of any thickness. An embodiment of this invention in which two Yagi antennas are stacked will be described below with reference to the drawings. FIG. 1 is a plan view of the antenna mounting bracket 1 of this invention, FIG. 2 is a front view thereof, and FIG. 3 is a left side view thereof. In FIG. 1, the antenna mounting bracket 1 includes two telescopic antenna mounting rods 2 and 3 arranged in parallel, and a telescopic support rod that supports the center portions of the antenna mounting rods 2 and 3. 4, and a strut mounting portion 5 for attaching the mounting fitting 1 to a strut. The antenna mounting rods 2 and 3 each consist of an outer rod 6 and inner rods 7 and 8 that are inserted from both ends of the outer rod 6, and their lengths can be adjusted depending on the insertion state. Sometimes, it can be fixed by tightening screws 9 and 10. Similarly, the support rod 4 is composed of an outer rod 11 and an inner rod 12 fitted into the outer rod 11, and its length can be freely adjusted and fixed with screws 13. Note that one end of the outer rod 11 and the antenna mounting rod 2
It is fixed to the center part of the outer rod 6 by, for example, welding,
Also, one end of the inner rod 12 and the outer rod 6 of the antenna mounting rod 3
The central part of the is also fixed in the same way. Furthermore, a receiving metal fitting 14 is fixed to the tip of the inner rods 7 and 8 of the antenna mounting rods 2 and 3, respectively, by, for example, welding. That is, the arm 17a of one Yagi antenna 17 is fixed to the receiving metal fitting 14 at one end of each of the antenna mounting rods 2 and 3 by a U-shaped bolt 15 and a nut 16.
An arm 18a of the other Yagi antenna 18 is similarly fixed to the receiving metal fitting 14 at the other end. Since this antenna mounting bracket 1 has the above configuration, by adjusting the length of the support rod 4,
It can accommodate any length of Yagi antennas 17, 18 to be stacked, and the antenna mounting rod 2,
Yagi antenna 1 by adjusting the length of 3
7 and 18 can be freely set. That is, the interval W and length L can be freely set according to the dimensions of the Yagi antennas 17 and 18 determined by the operating frequency and required performance. Next, the strut mounting portion 5 of the antenna mounting bracket 1 will be explained. As mentioned above, the conventional structure of this part was a dedicated fixing method. In this idea,
The support seat 19 has a special structure so that it can be attached to a support of any thickness using two U-shaped bolts 20 and nuts 21, and the belt-shaped support seat 19 shown in FIGS. The attachment fitting 40 allows it to be attached to a relatively thin pipe-shaped support such as a panza mast. That is, in FIGS. 2 and 3, the support support seat 19 has a square bottom portion 19b and four side portions 19a bent at right angles in the same direction from the four sides of the bottom portion 19b.
and a V-shaped notch 2 on each side surface 19a.
2, and four holes 23 for inserting the U-shaped bolts 20 into the bottom portion 19b are provided at equal intervals along each side. 4 holes 23
By making the U-shaped bolts 20 evenly spaced, the U-shaped bolts 20 can be inserted using the holes 23 located along the top or bottom sides, or the holes 23 located along the sides. be able to. Furthermore, two mounting holes 32 are provided in each of the four side surfaces 19a at a constant interval H for mounting band-shaped strut fastening fittings 40, which will be described in detail later. and,
The strut receiving seat 19 configured as described above is firmly fixed to the joint between the outer rod 6 of the antenna attachment rod 2 and the outer rod 11 of the support rod 4 by means such as welding. In FIG. 1, reference numeral 19' denotes a reinforcing member for firmly fixing the support seat 19 to the outer rod 11 portion. Therefore, in this strut mounting portion 5, the cutout portion 22 can be aligned with the outer circumferential portion of the strut 24 shown in FIGS. 2 and 3, and it can be firmly attached using the U-shaped bolt 20 and nut 21. As shown in FIG. 1, the U-shaped bolt 20 can be attached to a fairly thin support by making the central bent portion 20a of the U-shaped bolt 20 have a shape close to a V-shape, for example, with a small bending radius. Also, as mentioned above, the support seat 19
By providing V-shaped notches 22 on all four side surfaces 19a and setting the mutual spacing of all the four holes 23 provided in the bottom portion 19b to be the same, the column receiving seat 19 can be rotated 90 degrees to remove the column. 24, the usage conditions of the Yagi antennas 17 and 18 can be freely changed in terms of their plane of polarization. That is, the same antenna mounting bracket 1 can be freely set for either horizontal polarization or vertical polarization. Next, a case will be described in which the antenna mounting bracket 1 is applied to a comparatively conductive pipe-shaped support such as a panther mast. For example, in the case of a pipe-shaped support with a wall thickness of about 1 mm, if the above-mentioned U-shaped bolt 20 is used, the support may be deformed (dented) by the tightening force and cannot be firmly attached. There is. In such a case, the belt-shaped strut tightening fitting 40 shown in FIGS. 4 and 5 may be attached to the U-shaped bolt 2.
0, it is attached to the support seat 19, and it is attached to the thin pipe-shaped support via this belt-like support fastening fitting 40. Hereinafter, the configuration of the band-shaped strut fastening fitting 40 will be explained. 4 and 5, 25 is an L-shaped mounting angle, 26 is a so-called M seat having a circumferential surface (or V-shaped surface) 26a, 2
7 is a flexible arm band, 28 is a nut A, 29 is a bolt, and 30 is a nut B. Mounting angle 2
5, an M seat 26 is attached to the center of the outside of one side, and a bolt 29 is attached to the nut A2 on both sides.
6. Further, a nut B29 is screwed into the center of the bolt 29.
Both ends of the flexible arm band 27 are held by this. That is, the M seat 26 and the flexible arm band 27
By passing the pipe-like support 24a between the pipe-like support 24a and tightening the nut A28, the pipe-like support 24
A belt-shaped strut fastening fitting 40 is fixed to a. Furthermore, on the other side of the mounting angle 25, two mounting holes 31 are provided at a distance H, that is,
They are provided at the same spacing H as the mounting holes 32 formed in the side surface 19a of the support column receiving seat 19. Belt-shaped strut fastening fitting 40 configured as described above
The antenna mounting bracket 1 is installed as shown in FIGS. 6a to 6c.
On the other hand, it is attached to two opposing side surfaces 19a, 19a of the support column receiving seat 19, respectively. FIG. 6 shows a state in which the band-shaped strut tightening fitting 40 is attached to the strut receiving seat 19, and FIG. 6 a is a plan view, FIG. 6 b is a left side view, and FIG. 6 c is a front view. When installing the band-shaped strut tightening fitting 40, the mounting hole 31 of the mounting angle 25 is aligned with the mounting hole 32 provided in the side surface 19a of the strut receiving seat 19, and the bolt 3
3. Fix both with nuts 34. and,
The pipe-shaped support 24a is passed through between the M seat 26 and the flexible arm band 27 of each strip-shaped support fastening fitting 40, and the antenna mounting bracket 1 is attached to the pipe-shaped support 24a by tightening the nut A28. As described above, the support seat 19 of the antenna mounting bracket 1 is
By attaching the band-shaped strut tightening fitting 40 to the pipe-shaped strut 24a, the antenna mounting bracket 1 is attached.
can be firmly attached to the pipe-shaped support 24a. In this case, since the belt-shaped flexible arm band 27 is used for tightening, the relatively thin pipe-shaped support 24a
However, there is no deformation of the pillar. By configuring the support seat 19 as described above, it is possible to apply not only the U-shaped bolt 20 but also the belt-shaped support fastening fitting 40 using the flexible arm band 27 shown in FIGS. 4 and 5. Application is also possible. In addition, in the above embodiment, the antenna mounting rod 2,
3 and the support rod 4 are made of rod-shaped materials, and the expansion and contraction structure is an inserting and fixing method, but the invention is not limited to this. For example, they may be made of angle material, and a number of holes for connecting the two may be formed at appropriate intervals. Alternatively, the two may be formed and connected with bolts and nuts to the required length. The point is that the antenna mounting member and the support member each have a structure that is expandable and retractable.
In addition, in order to attach and fix the Yagi antennas 17 and 18 to the antenna mounting rods 2 and 3, the receiving bracket 14 and the U
Although an embodiment using a letter-shaped bolt 15 and a nut 16 has been shown, the present invention is not limited to this. For example, the arms 17a, 18a of the Yagi antennas 17, 18 and the inner rod 7 of the antenna mounting rods 2, 3 can be directly connected with bolts. It may be fixed with a nut. In short, any means that can firmly support and fix both may be used. Further, in the above embodiment, the side surface portion 19a of the support column receiving seat 19 has a bent structure, but it goes without saying that it may be formed by sheet metal processing using a drawing method, for example. Further, the antenna attached to this support is not limited to the Yagi antennas 17 and 18, but can also be applied to other parabolic antennas, horn antennas, etc. For example, in the case of a parabolic antenna, the column head 19 of this invention is attached to the mounting body, which is the pan head.
It is extremely convenient to apply. As mentioned above, in this invention, for example, three telescopic rod-shaped members are joined in an H shape, so that
Since the spacing between the antennas to be stacked and the length of the antennas can be adjusted to any desired length, it is possible to meet any specifications determined by the frequency of use and the performance of the antennas, and it can be commonly used in an extremely wide range. In addition, when attaching to a column, the structure of the column receiving seat is such that both U-shaped bolts and belt-shaped band mounting brackets can be used, so it can be applied to columns of any thickness, and can be attached to relatively thin pipe-shaped columns. can also be applied, and its scope of application is extremely wide. Therefore, since the antenna mounting bracket of this invention has been changed from the conventional fixed type to a variable type, it can be standardized over a very wide range and can be kept in stock as needed, allowing for mass production and a significant reduction in cost. Become. Furthermore, since the three rod-shaped materials are divided into multiple pieces along their length, workability during production, transportation, and on-site assembly is significantly improved, and packaging and transportation costs are also reduced.
