Description

[Detailed Description of the Invention] The present invention relates to a portable antenna installation device.

This invention provides a portable antenna installation device that can be used to check the reception status in advance in areas where satellite broadcasting is available or for reception by mobile models.It can be folded freely and transported anywhere. Moreover, antenna installation and construction are extremely easy.

Hereinafter, the present invention will be described in detail based on specific embodiments shown in FIGS. 1 to 5 attached hereto. In the folding tripod 1, a central vertical column 3 is fitted onto a support tube 2 from above and rotatably engaged with the support tube 2, and three extendable support legs 4 are provided on the outer periphery of the support tube 2 so as to be openable and closable. A horizontal support shaft 28 is rotatably supported at the top of the central vertical column 3 in an orthogonal manner, and adjustment bodies 5 are mounted on both sides of the horizontal support shaft 28. The horizontal support shaft 28 is horizontally rotatable around the central vertical column 3, and the horizontal support shaft 28 is fixed to the central vertical column 3 using a horizontal support shaft 28 attached to one vertical side wall 26 of the adjustment body 5. supporting shaft 28
This is done by screwing the fixing screw handle 7 on the end face. The vertical rotation of the adjustment body 5 is performed by the horizontal support shaft 2.
8, and the fixing is done by tightening the fixing screw handles 8, 9 screwed into the vertical side walls 6, 26, and then through the slits 10 carved in the vertical side walls 6, 26.
narrow the width and fix it to the support shaft 28. The front surface of the adjustment body 5 is formed perpendicularly to the vertical side walls 6 and 26, and a mounting plate 11 made of sheet metal and having a generally U-shaped cross section is fixed thereto. The intermediate portions of both side walls 12 of the mounting plate 11 are cut out, and four holding pieces 27 are formed at the upper and lower parts of the side walls 12, and each holding piece 27 is provided with a notch 13 that is open at the top. On the other hand, on the back surface of the reflector 14 of the offset parabolic antenna, a vertical rib 15 is provided at a cylindrical position corresponding to the side wall 12 of the mounting plate 11, and the vertical rib 15 is attached to the mounting plate 1.
A locking pin 16 is provided in a cylindrical position corresponding to the notch 13 of 1. The reflecting mirror 14 can be easily attached to the tripod 1 by hooking and engaging the locking pin 16 on the back surface with the notch 13 of the mounting plate 11. In addition, when removing the reflector 14, it is only necessary to lift the reflector 14 upward.A horizontal level gauge 17 is attached to the upper surface of the horizontal support shaft 28, and the other vertical side wall 6 of the adjustment body 5 receives antenna radio waves. A swing-down measuring device 18 capable of measuring the elevation angle is provided. The swing-down measuring device 18 consists of a side plate 19 and a measuring plate 20, and the side plate 19 is fixed to the vertical side wall 6 of the adjustment body 5 and has a reference line 21 engraved thereon that is orthogonal to the direction in which the radio waves arrive from the reflector 14. The measuring plate 20 is fan-shaped and has an angular scale engraved on its outer periphery, and its center point is set on the reference line 21 by a support shaft 22 in a swing-down manner.

Next, the operation of the above portable antenna installation device will be described. When installing this device at any location, open and extend the supporting legs 4 of the tripod 1, then engage the locking pin 16 of the reflector 1 with the notch 13 of the mounting plate 11, and attach the reflector 14 to the tripod 1. Install. Subsequently, the tripod 1 is held horizontally using the leveling level 17 on the top surface of the horizontal support shaft 28 on the top of the central vertical column 3 of the tripod 1. Next, the user grasps the fixing screw handle 8 and sets the azimuth of the reflecting mirror 14 using a magnet or the like, and then tightens the fixing screw handle 7 to fix the azimuth. Subsequently, the depression angle of the reflector 14 is set using the handle 8, and the handles 8 and 9 are tightened to fix it. At this time, the depression angle of the reflecting mirror 14 can be understood as the elevation angle from the angle displayed between the reference line 21 of the swing-down measuring device 18 and the measuring plate 20. When removing and transporting this device, remove the reflector 14 from the notch 13 of the mounting plate 11 and
It can be easily transported by contracting and closing. Note that 23 is a support arm, 24 is a converter, and 25 is an antenna-order radiator.

As described above, in the present invention, a horizontal support shaft is orthogonally supported rotatably at the top of a central vertical column, and an adjustment body is attached to the horizontal support shaft so as to be rotatable within a vertical plane. , a folding tripod in which the adjusting body can be rotated horizontally, the elevation can be varied, and fixed, and a mounting plate is provided on the front of the adjusting body to removably lock the back surface of the antenna reflector, and the horizontal position at the top of the central vertical column is This is a portable antenna installation device that is equipped with a leveling level on the top surface of a shaped support shaft and a swing-down measuring device on the vertical side wall of the adjustment body that can measure the antenna radio wave arrival angle of elevation, allowing you to use it anywhere. It can be folded and transported easily, and the antenna is extremely easy to install and set up.

Radio waves from broadcasting satellites have severe directional characteristics with a half-value angle of 2 to 3 degrees for parabolic reflector antennas, so the installation angle of the antenna for receiving satellite broadcasts must be easy to adjust. However, the present invention makes it extremely easy to attach the portable antenna and the installation device on-site and adjust the installation angle.
