Small KU antenna to increase the reflection surface to increase the received signal ----- Satellite Antenna Modify

Keywords: ku antenna transformation Any enthusiast who likes to starry is almost all, when the satellite is relatively weak, the signal has just pass the threshold or near the threshold, and the image beats and cannot get normal. It is anxious. Although the signal that has just been threshing is said that it can be barely watch, but the burning friends have experience, maybe the morning signal can be limited, in the afternoon or in the evening. The author now uses the 0.75ku antenna to receive 75 degrees of Sichuan, the Sichuan, the SAST 12518 V 22000 This group of signals is like this. Because the 75-degree Russian program is very strong, I don't want to turn other satellites, I can only find ways Solve the problem of weak reception signals. Increasing satellite power is impossible, then buy big antenna economy can not bear, can only find a way to plug in "wings" in the small KU antenna to increase the reflection surface of the antenna to solve this problem. Increasing the reflection surface of antennas is not an easy task, can only use existing conditions to solve it, for this, I have made some attempts and have achieved some effects. Material: Some of the iron (I use 30 25 cm three), hammers, hand clamp, electric drill, 6 mm screws, etc. Processing method: Take a hand clamping into 90 degrees with a hand clamping in 2 cm, and then drills 3 6 mm holes at a uniform drill at 2 cm in the bending, and processes other two iron. Then, the drill is mounted on the top of the antenna, and the edges of each side are neat (the edge of the author's Swick Antenna is also reduced by 90 degrees), and drilled the iron in the corresponding position. The original antenna is fixed with a screw. Debug: Put the receiver, monitor, high frequency head. After the cable is good, the debug must be patience, and should pay attention to the change of the signal indicator strip on the receiver. A piece of adjustment of the bending point of the iron and the front-rear inclination, which has been adjusted to the signal has a certain increase, even Successful. Look at the antenna, there is already a "wings". (Editor's Note: The antenna will increase the reflective surface. This is difficult for this surface. Therefore, the focus of the antenna will change, so it needs to be fully adjusted) Effect: 0.75KU antenna Kronberi before and after receiving 75 degrees satellite 12518V22000 A set of signals When the result is: Adapted to "wings" signal strength is 64. Signal quality 71. The signal strength is 58. The signal quality 62-64 (with severe mosaic). After the "wings" signal strength is 67. Signal quality 76. Signal intensity is 64. Signal quality 71 (stable reception).
