BACKGROUND OF THE INVENTION
  The present invention relates to a broadcasting system that transmits information to a service area on the ground using satellite waves, and in particular, enables a receiving terminal to receive information from a satellite even in an area that is hidden behind a building or a mountain. The present invention relates to a transmission antenna device with an amplifier that constitutes a gap filler device.
[0002]
[Prior art]
  In recent years, construction of broadcasting systems using satellites has been promoted. Since the radio wave used in the satellite broadcasting system is a signal such as S band (2.6 GHz), for example, it has a strong straightness and is reflected immediately if there is an obstacle that flies far away. If the receiving terminal is a mobile receiving terminal, broadcast information cannot be obtained when the receiving terminal enters a building or the like where direct waves from the satellite do not reach.
  Therefore, as a component of the above broadcasting system, it is present in various places on the ground by adding a gap filler device as a relay device for the ground that sends broadcast information toward the shadow of buildings where direct waves from such satellites do not reach. Information can be reliably provided to the receiving terminal.
[0003]
  FIG. 1 shows components of information transmission of a broadcasting system that is being constructed recently (the specific configuration of the gap filler device is partly different from that in the present invention). Therefore, the components of information transmission will be described below with reference to FIG. Reference numerals 1 to 5 denote known structures, which are normally used in a broadcasting system. 1 is a receiving antenna for receiving information (Ku band: 12 GHz) from a satellite, 2 is a converter that outputs a signal in the intermediate frequency band 1 GHz band, 3 is a cable for transmitting an information signal, 4 is an S band: 2. A signal processor 5 that outputs a 6 GHz signal, and a distributor 5 that distributes the signal toward a plurality of transmission antennas. Reference numeral 6 denotes an apparatus for transmitting radio waves having the same information as the satellite waves to a place where the S-band service using the satellite waves cannot be enjoyed. As a specific structure, an example conventionally known is shown in FIG. 1. Reference numeral 7 denotes an elongated rod-like antenna portion in which a base portion 7a is attached to a support 9 via a support fitting 50. , 8a is a transmission amplifier for amplifying to a prescribed power necessary for transmitting an information signal, and the case for housing the high output amplifier circuit is located below the support bracket 50 with respect to the support column 9. It is stuck.
[0004]
[Problems to be solved by the invention]
  In this conventional transmission antenna device with an amplifier, special consideration is required for the mounting bracket for mounting the base portion 7a of the elongated rod-shaped antenna portion 7 to the support column 9. In particular, since this type of antenna unit is arranged at a high place such as the rooftop of a building, it must be strong enough to withstand strong winds such as typhoons.
In order to enhance the gap filler effect, it is preferable to project the upper end portion 7b of the antenna portion 7 outward from the wall surface of the building. For this purpose, the base part 7a of the antenna part must be attached to the column 9 so as to be tiltable.
  In addition, the case 8a that accommodates a circuit that amplifies high-output power becomes high in temperature, and therefore must be configured to increase the cooling effect. For this purpose, it cannot be placed on the ground, and it must be mounted on a support as shown in FIG. 1 and floated in the air.
[0005]
  The purpose of this application is to maintain a vertical installation state firmly even when exposed to strong winds in a high installation state, and to maintain good high frequency characteristics forever. An object of the present invention is to provide a transmitting antenna device with an amplifier that can be maintained and can serve as a gap filler.
  Another object is to integrate the case of the transmission amplifier on the building by integrating the elongated rod-shaped antenna section and the case for accommodating the high output amplifier circuit in the transmission amplifier. It is an object of the present invention to provide a gap filler device that can finish the mounting operation with labor.
  Another object is that when the elongated rod-shaped antenna part is vertically established with a slight inclination, a large bending force is applied to the base part. It is intended to provide a transmitting antenna device with an amplifier which is formed in a structure that can be elongated in the vertical direction and can sufficiently withstand the bending force of the antenna section.
  Another purpose is that the back side of the case is large around the space for accommodating the amplifier circuit.Side openingTo make it easier to accommodate the amplifier circuit in the factorySide openingBy using the side as a mounting surface for the building, after installing the gap filler device on site,Side openingIt is an object of the present invention to provide a transmitting antenna device with an amplifier in which the lid attached to the above is opened so that the amplifier circuit is not tampered with.
  Another purpose is that the transmission amplifier case contains a circuit that amplifies high output power, and the temperature becomes high. However, as described above, the mounting surface of the transmission amplifier case is lengthened in the vertical direction. Thus, by forming the antenna portion so as to sufficiently withstand the bending force of the antenna portion, the length of the case in the vertical direction is increased, and a transmission antenna device with an amplifier is provided in which the cooling effect is remarkably improved. It is what.
  In addition, the purpose of this application is to enable workers who investigate and adjust the performance of electronic circuits stored in the case of a transmitting amplifier placed at a high place and in a poor position to work without feeling dangerous. Therefore, it is an object of the present invention to provide an amplifier-equipped transmission antenna device configured to be able to perform a safe work at a position close to a building with a low posture.
  Further, the object of the present application is to form a very long columnar shape by connecting the base portion of the rod-shaped transmitting antenna portion and the head portion of the columnar or prismatic base portion. However, it is intended to provide a transmitting antenna device with an amplifier having a structure that can be divided into two parts in handling on-site delivery and the like so that they are relatively short and easy to handle.
  Other objects and advantages will be readily apparent from the drawings and the following description associated therewith.

Since the elongated rod-shaped antenna portion and the case 27 for accommodating the high-power amplifier circuit for transmission are integrated, the case 27 for accommodating the amplifier circuit for transmission is attached to the building. Thus, there is an effect that the mounting work of the rod-shaped transmitting antenna unit 7 can be completed with only the effort.
[0023]
  Further, by forming the electronic device storage space 25 provided in the base main body 10 in the base portion so as to be long in the vertical direction, the building mounting portion 16 provided on the back side of the peripheral wall of the case portion 27 is also in the vertical direction. There is a feature that makes it possible to form it so that it can be formed long, and by connecting the mounting part, which can be formed long in the vertical direction, to the building 9, a powerful transmission from the rod-shaped transmitting antenna part 7 is achieved.

  Further, in the present invention, by forming the electronic device storage space 25 provided in the base portion 8 to be long in the vertical direction, the peripheral wall of the case portion can also be long in the vertical direction. This makes it possible to increase the length in the vertical direction of the heat dissipation plate that protrudes in the radial direction on the peripheral wall of the case portion 27, and has an effect of significantly improving the cooling effect. In addition, by projecting the heat sink toward the radial direction from the peripheral wall of the case part, and by increasing the length in the vertical direction,
The reinforcing effect of the base body is improved, and the effect of maintaining the antenna part even when the antenna part is exposed to a strong wind increases.
[0026]
