1) Try to avoid debugging in rainy or snowy days when searching for stars. Bad weather will cause great signal loss. In addition, you should also know whether there is interference from sunspots and whether the clouds are too thick during debugging. Even if it is debugged in fine weather, if the weather where the signal source is transmitted is bad, the signal strength will be affected, and sometimes the debugged transponder will stop broadcasting or the satellite TV program parameters have been changed.
(2) During the debugging, a group of transponders with the strongest signal in the TV Satellite Antenna should be selected, and after receiving the signal, carefully adjust to the best point so that the weak signal can be watched satisfactorily.

(3) Do a good job of protecting satellite antennas.
First, pay attention to wind, fix the base of the ground receiving antenna, and fasten the screws to prevent it from being blown over by the wind
Second, pay attention to lightning protection. The Satellite Antenna should be properly grounded and the ground resistance should be less than 4Ω. When the satellite antenna is too high, it is best to erect a lightning rod next to the satellite antenna to ensure that the satellite antenna is not struck by lightning.
Third, pay attention to rust prevention. As there are more and more satellites in the sky, the ground receiving antenna will be adjusted frequently, so grease should be applied to the adjustment screws such as azimuth and elevation to facilitate the next operation.
Fourth, pay attention to rain and snow. The tuner and cable joints should be wrapped with waterproof tape to prevent rainwater from entering the Television Satellite receiver along the cable. If the components are damaged, snow should be removed in time when there is heavy snow in winter to ensure the viewing effect. Fifth, pay attention to preventing moths. The old-fashioned feeder nozzle is not covered, and it is easy to live in insects such as bees and spiders. It should be checked regularly.
(4) Make a record, including the satellite name and satellite TV parameters, satellite TV program name, band, downlink frequency, symbol rate, polarization mode, encryption, satellite adjustment time, technicians, etc., for reference when adjusting again, Draw on.
In short, the accuracy of the satellite ground antenna to the satellite is the first hurdle to determine the quality of the received signal, so you must be patient when adjusting. If you are not familiar with the adjustment of the satellite ground antenna or lack experience, you can use some satellite adjustments. Assistive equipment, such as: compass, star finder, inclinometer, etc., or ask a technician who is familiar with this work for help. As long as you have prepared in advance and adjusted patiently and meticulously, you will quickly adjust the satellite antenna and receive satellite TV programs with excellent sound and image.
