Description

Satellite Antenna to Install Using Shadow of Sun and Its Installation Method {.}

[Field of Invention]

The present invention relates to a satellite antenna.

More specifically, the present invention relates to a satellite antenna installed by a shadow of the sun and a method of installing the same.

[Background of invention]

Satellite antennas are installed toward satellites and used as devices for transmitting and receiving satellites.

Satellite antennas are most commonly used as reflectors that reflect the transmitted and received radio waves. Among them, there are several types of satellite antennas, and those that absorb the received radio waves.

Other undirected satellite antennas are also used.

Among these various satellite antennas, the directional satellite antenna must adjust its angle toward the satellite.

Therefore, when installing a satellite antenna, a goniometer, compass, level meter, or spectrum is mobilized. These measuring devices are complicated in structure and cannot be permanently coupled to the antenna, and are detachable as necessary. It is very difficult for ordinary consumers to install satellite antennas directly.

In particular, the level meter and the spectrum can react only when the antenna angle reaches an approximate value, but only when the signal of the satellite starts to be received.

These problems are especially true when using digital signals, which are rapidly spreading in recent years.

Thus, the present inventors have a purpose to provide a satellite antenna that can be easily used by all consumers because the structure is very simple, and the response of the satellite antenna is far beyond the approximate value. A satellite antenna has been developed, and a patent application for this antenna has already been applied and a patent application is being continued.

Previously patented inventions have significant breakthrough advantages over other satellite antennas, but have the following disadvantages.

First, it was difficult to locate the shadow generator.

In other words, if the crosshairs of the shadow generating device are installed close to the angle table, the distance to the shadow formed on the angle table will be close, and the distance of the shadow moving by a certain time will be shortened. It is difficult to set the location of the shadow generator that can be conveniently used in these various situations because the location of the shadow is short within the range of the angle table, and there is also a big difference in the shadow location for each satellite that is directed seasonally by region.

Second, it was inconvenient to print the angle table on most of the front of the antenna.

The inventors seek to provide a satellite antenna that solves even the two problems mentioned above.

The object of the present invention,

Provides a satellite antenna for installation using the shadow of the sun, but makes it easier to install the antenna by using the shadow of the furthest point away from the shadow generator, despite the change of region and season. It makes it possible to produce the angle table that was difficult to print in a simple way, and in some cases, it provides the convenience of using the shadow position calculation program and finding the corresponding shadow position in the printed shadow trajectory.

The above main and other objects are all achieved by the present invention described below.

FIG. 1 and FIG. 5 are side views of satellite antennas, and FIGS. 2, 3, 4, and 6 are front views of respective satellite antennas, mainly showing a shadow generator and an angle table.

FIG. 7 is an obstacle identifying apparatus, FIG. 8 is a structure of lowering the shadow generating apparatus, FIG. 9 is a structure fixing the lower portion of the shadow generating apparatus by a clip, and FIG. 10 is an upper portion of the shadow generating apparatus.

The above drawings are all schematically shown.

The present invention is practiced as follows.

First way:

While checking the horizontality of the satellite antenna in the left and right directions, the scale 18 of the angle table 17 and the scale (18) according to the season, date, time, region, and satellite to be oriented to which the satellite antenna 1 is to be installed. Calculate the scale 18 of the shadow generating device 5, which should be matched to, and according to this calculation the portion of the specific scale 18 of the shadow generating device 5 on the specific scale 18 of the angle table 17. To match the shadow of the obstacle checker to determine whether the obstacle within the angle range of the antenna directed.

Second way:

While checking the horizontal position of the satellite antenna in the left and right directions, the shadow track (5) corresponding to the satellite and the date to which the satellite antenna (1) will be directed is found on the angle table (26), and then the corresponding visual part of the shadow track (5). Find and match the shadow of the specific graduation portion of the shadow generating device 5 to the corresponding time portion, and by the obstacle checking device to determine whether the obstacle within the angle range that the antenna is directed.

The position of the shadow on the angle table and the corresponding scale of the shadow generator are calculated as follows.

The location of the shadows can be calculated astronomically using seasons, dates, time, coordinates on Earth, and satellite positions.

Based on this principle, we make shadow position calculation program.

Since satellite antennas are often used together with devices such as satellite broadcasting receivers, the shadow positioning operation program is installed in the satellite broadcasting receiver, or the shadow positioning operation program is used through the Internet homepage, or by using a telephone. You can send and receive values about the shadow location.

For example, the operation program is installed in the satellite broadcasting receiver. For example, turn on the satellite broadcasting receiver, go to the installation program, select the name of the satellite and follow the on-screen instructions to install the satellite antenna. Just choose the name of the area and it will give you information about the shadow.

The program has a built-in calendar and clock so you don't have to enter dates and times.

Therefore, in the present invention, despite the change of region and season, it is possible to install the antenna more easily by using the shadow of the farthest point from the shadow generating device, and the angle table which was difficult to print extensively on the front of the antenna is simple. In this case, it is possible to selectively use the method of using the shadow position calculation program or the method of immediately finding the corresponding shadow position in the printed shadow trajectory.
