Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an antenna mount, and more particularly, to an antenna mount capable of freely adjusting an omnidirectional (hereinafter referred to as "omni antenna") to an arbitrary elevation or depression angle.

[0002]

2. Description of the Related Art Conventionally, when mounting an antenna, as shown in FIG. 8, one support 30 is fixed to a tower main body 31 to form an antenna mount, and as shown in FIG. In many cases, the antenna 32 is fixed to the column 30 via the fastener 33, and the variable angle of the antenna 32 can be changed by 360 degrees in the horizontal direction (X direction), but can be changed in the vertical direction (elevation angle and depression angle). Could not adjust the angle.

As shown in FIG. 10, the omni antenna 34 has an effective radio wave transmission / reception angle of 360 degrees in the horizontal direction, but generally has 0 degrees (elevation angle and depression angle) in the vertical direction. ± 2 degrees), 4 degrees (± 2 degrees), 6 degrees (± 2 degrees)
) And the angle are fixed, so that the omni antenna 34
Is fixed to the tower 31 once, it is impossible to transmit and receive radio waves to and from the opposite station 35 located at an intermediate angle between the above angles. In order to achieve this, it was necessary to remanufacture the gantry based on the required angle.

Therefore, the present invention has been made in view of the above-mentioned problems in the prior art, and has been made in view of the fact that the gantry itself can be freely adjusted together with an antenna so that an arbitrary elevation angle or depression angle can be obtained. The object of the present invention is to provide an antenna mount that allows the antenna mount to be tilted to an intermediate angle of the conventional adjustable angle so that an opposite station that could not transmit and receive radio waves can transmit and receive radio waves. And

[0005]

According to the first aspect of the present invention,
In a column for fixing an antenna via a fastener, a base to which the column is fixed, and a connecting means for fixing the column and the base, an antenna mount includes a bottom portion of the column. The support is pivotally fixed to the base by forming the base in a spherical shape and forming a contact portion of the base with the support as a spherical recess.

According to a second aspect of the present invention, the connecting means includes:
A wire for connecting the support and the base and a turnbuckle provided at an intermediate portion of the wire.

According to the first aspect of the invention, the bottom of the column is formed in a spherical shape, and the contact portion of the base with the column is formed as a spherical concave portion. Because it is fixed so that it can pivot, it is possible to freely adjust the antenna to any elevation or depression angle, etc.
The angle of the antenna for transmitting and receiving radio waves to and from the opposite station can be easily adjusted.

According to the second aspect of the present invention, the connecting means comprises a wire for connecting the support and the base and a turnbuckle provided at an intermediate portion of the wire, so that the turnbuckle is adjusted. This makes it easier to adjust the angle of the antenna for transmitting and receiving radio waves to and from the opposite station.

[0009]

Next, a specific example of an embodiment of an antenna mount according to the present invention will be described with reference to the drawings.

FIG. 1 is a view showing an embodiment of an antenna mount according to the present invention.
A column 2 to which the omni antenna 10 is fixed, and the column 2
Are fixed, and a fixing wire 4 or the like as connecting means for fixing the support 2 and the base 3.

The column 2 is formed in a columnar shape, and is provided for fixing the omni-antenna 10 via a fastener 11. As shown in FIG. 2, the bottom 2a of the column 2 is formed in a spherical shape, and slides on a surface of a concave portion 3c formed in the center of a substrate 3a described later. In addition, this bottom part 2a is shown in FIG.
As shown in FIG. 4, an iron ball 2c may be formed by welding the tip of the support column 2 to the front end of the support post 2. Alternatively, as shown in FIG. It may be formed in a shape.

The support 2 and the base 3 are provided on the surface of the support 2.
Is provided with an attachment portion 2b of the fixing wire 4 for connecting the two.

As shown in FIG. 5, the base 3 is composed of a table-shaped substrate 3a and a columnar portion 3b. The bottom 2a of the column 2 is provided at the center of the upper surface of the substrate 3a as described above. A concave portion 3c is formed for receiving. At the corner of the upper surface of the substrate 3a, a mounting portion 3d for the fixed wire 4 is provided.

As shown in FIG. 1, the support 2 and the base 3
The connection is made by the fixing wire 4.
The turnbuckle 5 is provided at an intermediate portion of the turntable, as shown in FIG.
It is composed of a left screw 5b, a right screw 5c, and a centerpiece 5d. The centerpiece 5d is connected to the fixing wire 4, and the fixing wire 4 can be tightened by rotating the sleeve 5a. .

Next, the antenna mount 1 having the above configuration
Will be described. As shown in FIG. 7, when the omni antenna 10 is attached to the tower main body 31, transmission and reception of radio waves to / from the opposite station 35 may not be possible unless the elevation angle or depression angle of the omni antenna 10 is adjusted. In such a case, as shown in FIG. 1, the bottom 2a of the support 2 is positioned in the recess 3c of the base 3, and the angle of the support 2 with respect to the surface of the substrate 3a is adjusted by sliding on the surface of the recess 3c. adjust. Thereby, the elevation angle or the depression angle of the omni antenna 10 can be adjusted.

When the angle of elevation of the omni-antenna 10 ′ capable of transmitting and receiving radio waves to and from the opposite station 35 is obtained by adjusting the angle of the column 2 with respect to the surface of the substrate 3 a, the base portion is fixed via the fixed wire 4. The support 2 is fixed to 3. At this time, the tension of the fixing wire 4 is adjusted by adjusting the turnbuckle 5, and the column 2 is firmly fixed.

In the above-described embodiment, the case where the elevation angle or the depression angle of the omni antenna is adjusted has been described. However, other types of antennas are also mounted by turning the column to which the antenna is fixed with respect to the base. The direction can be adjusted, and the antenna mount according to the present invention can be applied to not only the case where the upper surface of the base substrate is horizontally arranged but also the case where the substrate is inclined or vertically arranged.

[0018]

As described above, according to the present invention,
The antenna can be freely adjusted to an arbitrary elevation angle or depression angle, and the angle of the antenna for transmitting and receiving radio waves to and from the opposite station can be easily adjusted.
