First, equipment

Thunder 430XP receiver, good news four cut a switch l only.

Depending on the shell 122kHz switch, the digital Scitech C head 3 is fierce, and the PBI Ku head is only 1. One shared terminal, one side of the 1.8m antenna, and one ATV 8185 receiver

Second, the installation process

First, a single reception is performed on the satellites to be received. After the program parameters on a single satellite are all received, the main focus and the focus can be selected. The author takes the star 6B of 115.5°E as the main focus.

105.5°E, 122°E, 125°E, and 138°E are used as the partial focus. After the signal of Zhongxing 6B is adjusted to the best, the same is determined. The serial numbers stored in each of the receivers are then recorded on a piece of paper. In order to observe the signal quality change of the set of parameters during the star search process, then the c head with the feed disk is rotated to draw an arc search signal around the fixed main feed high frequency head. And always pay attention to the signal quality changes of the receiver. Because 105.5 ° E and 125 ° E and 115.5 ° E difference longitude is only lO. Left and right, so the method of looking for the arc in the Ku head is also applicable to the C head. At the moment when the signal is increased, a mark is placed on the position corresponding to the c-head. And the fixture made of aluminum alloy is used for Zhouding. The rest of the satellites use the same method. In less than two hours, they will find the corresponding signals one after another. After fixing and fine-tuning it, you can connect the four-cut switch. And the 22kHz switch downstairs to enjoy the holiday.

Third, the experience summary

1. Each satellite should be received separately during installation.

2. When selecting the main focus, you should select the one near the middle of the satellite you want to receive as the main focus. The second thing to note is that when selecting the defocus, the longitude of the C-band defocusing satellite is within 15° of the main focal length. According to the author's experience of installing more than one pot for many years, the C-band requires more conditions. For example, the size of the receiving antenna is mostly above 1.2m. The Ku band is different. When the antenna is more than 30 degrees away from the main focus satellite, it can receive smoothly as long as the antenna is large enough. Of course, we must also pay attention to the fact that if one or two satellites are received, the field strength of one or two satellites is weaker in the local area. And it is received as a focus. Then you can't put all the programs on the star in F.

Fourth, the installation experience

In the process of debugging, just look patiently and slowly.

The signal can be quickly found, and with the shared terminal, the programs on the 138°E star can be decoded smoothly, and the program is smooth when the channel is selected.
