卫星天线方向的现场调试（Field debugging of satellite antenna direction） Chinas satellite TV industry has made remarkable achievements in the past 10 years, and has increased the national television coverage to 82%. Now people have gradually cannot do without satellite TV, and by their interests in the country established nearly 50 thousand unit station satellite TV to receive high quality, and constantly increase in the pace of technical indicators of the quality of equipment, the receiving station. Because of the vast territory and complex terrain, we can expect that the construction of satellite TV receiving station will continue to develop rapidly over the next period of time. For the construction of satellite TV receiving station, the debugging work after completion needs some practical and easy to master methods. Therefore, to explore some simple debugging method is of practical significance, even for some of the professional skills of engineering and technical personnel, can use some simple methods such as in any case can still achieve good results, Why not?? Therefore, this article aims to make some practical discussions from these aspects and make common comments with readers and friends. The reception of satellite TV programs, whether it is the current C band or the KU band to be enabled, is the main form of the receiving antenna. Its structure, principle and technical design and calculation, installation, adjustment and target test of the receiving station are introduced in this paper. Debugging for satellite antenna, which comprises the antenna (elevation and azimuth), feed position, polarization orientation and polarization angle adjustment such as the number of items, the most critical one is the antenna elevation and azimuth. For its calculation formula of the principle and derivation, as well as the solution of the chart, also have more than taught in detail. However, in the literature, mostly focus on systematic and theoretical discussion, specific methods of op
