Here are some tips on the use of satellite antennas shared by Satellite Antenna Suppliers. I hope it will be helpful to everyone.
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 during debugging and whether the clouds are too thick. Even debugging in fine weather, if the weather where the signal source is located is bad, the signal strength will be affected. Sometimes the debugged transponder will be stopped, the satellite TV program will be overhauled on Tuesday, or satellite TV program parameters have been changed. .
2. In the debugging, a group of transponders with the strongest signal in the satellite 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 in the protection of Satellite Antennas. First, pay attention to wind protection, fix the base of the ground receiving antenna, and fasten the screws to prevent it from being blown down by strong wind; second, pay attention to lightning protection, the satellite antenna should be properly grounded and the ground resistance should be less than 4Ω, and the satellite antenna location 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 butter 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 satellite TV receiver along the cable. If the components are damaged, the 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, it is easy to live in insects such as bees and spiders, and 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 method, encryption, satellite adjustment time, technical personnel, etc., for reference and reference when adjusting again .
In short, the accuracy of the satellite ground antenna to the satellite is the first hurdle that determines the quality of the received signal, so you must be patient when adjusting. If you are not familiar with or lack experience in the adjustment of satellite ground antennas, 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.
