Kind of a pot of double star satellite receiver, Satellite TV Antenna DIY
Keywords: satellite TV antenna reform
Author: Zhang Zhiyang
At present, the arrival of Zhongxing No. 9 live satellite receiving system has been fully launched, and the C-band cauldron has been referred to. For the hot scene of the small pot hot sale, if there is more than 600 yuan to have a formal reception system, the worst a set of more than 300 yuan replacement cost, what should I do if I can eliminate the machine? Don't you take it back? The resources are wasted, and they are also increasing secondary pollution! Therefore, the author recommends using a two-star reception, and there is a small number of accessories to continue to use.
Through experiments, it is less than 50 yuan to increase the cost of a pot of two-star reception, and it is easy to get 50 sets of TV programs, and save money, and the effect is obvious.
Ingredients: a double star clamp (actual set can be dismantled into two depths), 4 yuan, depending on the beekend, one switch, 8 yuan; ordinary bipolar single output C-band high frequency head, 25 yuan High quality 75-5 cable mode, 8 yuan; British F head 4, 1.2 yuan; total 46.50 yuan.
The above is calculated according to the new purchase, if the high frequency head, the cable, the F head is available, the cost is only around 16 yuan.
First, the specific practice first step: first school, a large pot cover, try to colort all the TV programs on the satellite in Zhongxing, finely adjust the azimuth of the original antenna, elevation and polarization angle, generally in Hunan Taiwan, Qinghai Terrace and Chongqing Taiwan, weather channel, etc. can play smoothly and have a certain amount of balance.
Step 2: Remove one side of the film, first fix the corner screws of one of the feed plates to the left hole of the connecting piece, the two are present 90 °, and the right hole end of the connecting plate is above the upper right upper right. Support the rod and the screw of the feed source disk.
Step 3: Connect the feeder, high frequency head, receiver, and monitor, power supply, fine-tuning connector and the angle of the strut (this point is easier to output with a single-polarized single output high frequency, but it is difficult to firmly ) Try to find a signal, the author is the strongest, then observed the tower and Heilongjiang Taiwan, and reaches the reception threshold.
Next, do the F head, connect the switching switch, make fixed and waterproof processing, Xinnuo No. 3 in the "ON" terminal, Zhongxing 6B in the "OFF" end; if necessary, set the parameters on the receiver, 22KHz switch .
Second, the technical essentials 1, the struts of the satellite antenna must be solid and reliable, can not be shaken around, otherwise, it is difficult to succeed.
2. Looking for a signal when testing is a key and difficult, to be meticulous, patient, slowly.
3, a pot of 1.2 meters and 1.5 meters or more double stars (regardless of board shape or mesh), the difference is that the front right corner of the support rod in the top of the support rod, while the latter is in the upper right corner, the connecting sheet and the support rod respectively There is a 95 ° and 5 ° angle, only the high frequency head position is different, and the polarization direction is basically parallel.
4. The altitude of the author is 1100 meters, the east is 100 °, and the north latitude is 25 °.
5. In order to ensure the balance of the received signal, the main focal medium star 6b high frequency head should try to purchase high quality and efficient brand-name products. Through comparison, the current potted double star (receiving Zhongxing 6B and Xinnuo 3) and the broadcast TV program received by Zhongxing No. 9 live satellite is roughly the same, and even more. Only the common receiver used by Double Star Receive cannot decode CCTV news platform, the stability of Zhongxing 6b is different, and there is no special machine to use. Therefore, the author believes that if the user currently has a large pot, it can be used to receive the domestic Satellite TV program, and there is no need to buy it without a buyer.
