Screen Antenna
The exact position of the converter can be determined experimentally by moving it into the holder with the simultaneous assessment of the quality Pictures on the screen. It is certainly possible if the converter will be available after installation of the antenna in place, not 'hang' in the air five feet from the wall, blocking you from the mirror dish. In this case, we can offer two ways. You can find out the exact position of the converter from a seller in your system, and can spend "training" set in an accessible place and by determining the exact position of the converter, reposition your antenna to the final selected location. Sometimes it is not only accurate converter unit focused antenna, but also the correct position relative to the axis of rotation of the converter. Typically, each converter (refers to converters, monolithic combined with the polarizer and the radiator, which are used to mount the antenna on a satellite) is labeled "top", which is associated with the position of the built polarizer (corresponds to vertical polarization). But just up this label should only look at the satellite longitude.
If you install the dish east or west than the satellite, the converter must turn in a holder around its axis (see Fig. 2). Angles of rotation of the converter depending on the latitude and longitude of the difference between the position and the satellite are shown in the chart (Fig. 3). From the graph it is easy to see that the effect is more pronounced than further south (closer to the equator) you and are farther away from you (below the horizon) is a satellite.
