Abstract

(57) [Abstract] [Purpose] To improve the appearance by passing the cable connecting the antenna device and the receiver through the support arm and the mast. A cable 7 from a CS polarization switching device 2, a cable 9 from a CS converter 6 and a cable 10 from a BS converter 8 are wired through a hollow support arm 11 and a hollow mast 14. The cable 17 from the drive 13 is routed through the hollow mast.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a CS / BS antenna device, and to disposing a cable used for the device in a hollow support arm and a hollow mast.

[0002]

[Prior art]

 Conventionally, to receive the radio waves transmitted from CS / BS satellites with one antenna, it was realized by changing the direction of the parabola part by remote control. FIG. 2 is a perspective view of a conventional CS / BS antenna device, and 1 is a parabolic unit for receiving radio waves transmitted from a CS / BS satellite. Reference numeral 4 is a portion for introducing the radio wave received by the CS feedphone unit. A CS converter 6 low-noise amplifies the radio signal to convert the frequency. 9 is a coaxial cable which sends the signal from the CS converter 6 to the receiver. Reference numeral 2 is a CS polarization switching device that switches between horizontal polarization and vertical polarization. 7 is a 3-core cable, and a switching signal is sent from the receiver. Reference numeral 5 is a portion for introducing radio waves received by the BS feedphone unit. Reference numeral 8 is a BS converter that amplifies the radio signal with low noise and converts the frequency. Reference numeral 10 is a coaxial cable that sends the signal from the CS converter 6 to the receiver. A support arm 11 supports the above-mentioned feedphone unit, converter and the like. A clamper 12 fixes the two coaxial cables and the three-core cable described above to the support arm 11. Reference numeral 13 is a driving device for aligning the direction of the parabolic unit 1 with the CS / BS satellite. The drive unit 13 is connected by the three-core cable 7 from the receiving unit and operates the drive unit 13 by the control signal from the receiving unit. As described above, there are three cables coming out of the radio wave receiving section. This cable is clamped to the support arm 11 and is fixed to the mast 14 with the clamper 12 together with one cable from the drive unit 13. It is led below 14. In the past, each cable had to be clamped to the support arm 11 and the mast 14, which was not desirable in appearance, and there was a problem that the cable was damaged by the vibration of the cable due to wind or the like.

[0003]

The present invention has been made in view of the above conventional problems, and improves the appearance by passing a cable connecting an antenna device and a receiver through a support arm and a mast. aimed to.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, in the present invention, in a CS / BS antenna device that receives radio waves transmitted from a CS / BS satellite, a cable connected to a CS polarization switch, a CS converter, a BS converter, etc. is hollow. It is characterized in that the wires are routed through the support arm of.

[0005]

[Action]

 According to the above configuration, the three cables connected to the CS polarization switch, the CS converter and the BS converter are wired through the hollow support arm and the hollow mast, and are connected to the drive unit. The cable is routed through the hollow mast and guided under the mast.

[0006]

【Example】

 Embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a sectional view showing an embodiment of the CS / BS antenna device of the present invention. Those having the same functions as those in FIG. 2 are designated by the same reference numerals, and detailed description thereof will be omitted. In the figure, 15 is a hole for passing a cable provided in the support arm 11 and the mast 14. Reference numeral 16 denotes a tip end portion of the support arm 11, which holds the CS / BS converters 6, 8 and the like. A support base 18 supports the mast 14. The cable 7 from the CS polarization switching device 2, the cable 9 from the CS converter 6 and the cable 10 from the BS converter 8 are passed through the hole 15 of the hollow support arm 11 and the hole of the support arm 11 near the mast 14. Then, it is taken out of the mast 15, passed through the hole 15 of the mast 14 again, and lowered to the lower part of the mast 14. At the bottom of the mast 14, pull out from the hole 15 of the mast 14 to the outside. On the other hand, a cable 17 from the driving device 13 is passed through the mast 14 through the same hole 15 as the hole 15 of the mast 14 through which the cables 7, 9, 10 are passed, and is lowered to the lower part of the mast 14. At the bottom of the mast 14, pull it out through the hole 15 of the mast 14 together with the other three cables.

[0007]

[Effect of device]

 As described above, in the present invention, since each cable is arranged in the support arm and the mast, the appearance is cleaner and looks better than the conventional method in which each cable is clamped to the support arm 11 and the mast 14. To do. And the effect that the cable is not rubbed by wind and scratches is not significant.
