番組を同時に送ることができる大きなメリットがある。Recently, experiments and practical use using broadcasting satellites have begun. Broadcasting satellites emit, for example, television broadcast waves from geostationary satellites at the equator.
Broadcasting is directly received and enjoyed by each home in the local area without going through an earth station, eliminating the need for conventional microcircuits that require huge amounts of money. This has the great advantage of being able to send content programs at the same time.

しかも質の悪い電波を受信しているといのライ1視聴問
題が山積しており、これらを解消するには想像を超える
費用が伴うのであるか、1つの放送衛星はこれら諸問題
を一挙に解決してしまうのである。Particularly in households hidden behind high-rise buildings in subcommittee meetings, there is a problem in which radio waves from transmission towers cannot be received well for 1 minute, and in remote islands and remote areas, broadcasting equipment is not sufficient, so the radio waves from only a few stations and of poor quality are a problem. There are a lot of problems with RAI 1 that are being received, and resolving them will cost more than you can imagine, but a single broadcasting satellite will solve all of these problems all at once.

ワーを向いて取り付けられていた八木空中線は赤道−L

ことになる。With the advent of the era of broadcasting satellites, the Yagi antennas that had been installed on the roofs of each home facing the tower were now equator-L.
A parabolic antenna will be attached to the static image satellite.

れ以1−では良好な受信は望めない。The problem here is that in the current situation, the Yagi antenna only needs to be rotated horizontally at 3600 degrees and the tower is directed in one direction, and radio waves can be received well if the direction is in the opposite direction. Therefore, antenna installation 1-military equipment does not require much precision. 1. While navigating, when receiving weak radio waves from a broadcasting satellite with a parabolic antenna, ii:
, 11- It is necessary to point the parabolic antenna exactly in the direction of broadcast technique J11. This accuracy can be improved as the output of the broadcasting satellite increases.Although it is possible to increase the tolerance M of the ζ setting, it is possible to achieve this accuracy by measuring the weak radio waves from the sky in the best possible way. To receive it in the morning, first send the antenna to i.
The first thing to do is to point in the L direction, that is, toward the satellite. Moreover, unlike the current situation, it is not only the east direction of the water, but also the 1-
Since the downward direction also falls within the installation requirements, the installation work is extremely difficult, similar to that of a typical Jc. Whether or not good radio waves can be received no matter how far the parabolic antenna is oriented toward the broadcasting satellite is determined by the output of the broadcasting satellite and other conditions. However, the angle is generally limited to a few degrees, and good reception cannot be expected at angles beyond that.

その現象はより多くなるものと考えられる。On the other hand, if such systems become commonplace and enter every household, new problems will arise. It is a problem of ←j parabola type middle line direction. Even today, when the reception of a television receiver becomes poor, people mistakenly think that the problem is with the antenna system, even though the problem actually lies with the antenna system, and people often turn the adjustment knobs without realizing it, or service personnel are called out. Phenomena such as "calling" have been observed, but it is thought that such phenomena will become more common as the era of parabolic antennas for home use arrives.

To an untrained eye, it appears that the television receiver itself is malfunctioning.

利である。Therefore, the strength of the radio waves received by the parabolic antenna is ia
If the radio field strength reaches a certain value or higher, it will be displayed and the user will be informed that the parabolic antenna is not pointing in the correct direction. It is convenient because you can immediately know that there is a problem with the orientation of the parabolic antenna and take appropriate measures.

。FIG. 2 shows a display circuit of the present invention. A part of the received signal received by the parabolic antenna 1 is applied from the terminal 4 to the Schmitt trigger circuit 5. The received signal is constantly detected by the signal circuit 5, and when the level of the received signal is higher than a certain fixed level, the transistor 6 is turned on and the display lamp is turned on. 7 is turned on, and when this indicator lamp 7 is on, it is displayed to the user that the parabolic antenna 1 is correctly oriented in the direction of the satellite.

見つけ出すのにもきわめて便利なものである。Therefore, you can immediately go to adjust the direction of antenna 1. If you still cannot get a good reception condition, you will know that the cause is in the circuit of the pre-vision receiver itself. In addition, this indicator lamp 7 is extremely useful for easily finding the correct satellite direction when a new parabolic antenna is installed or replaced during normal use.

By using such an adapter, the conventional 6J1 TV receiver 3a can be used as is.
This is a feeder line that connects the adapter 8 and the television receiver 3a.
