Precautions and experience sharing for Using TV antennas Notes It is best to place it as vertically as possible and avoid folding. Any communication product has an electromagnetic field reflection. TV antennas are generally vertically polarized, and placing them vertically is the best position for vertical polarization. 2. Rotate at multiple angles to find the best position for receiving signals. Once the position and direction are fixed, do not move any further. 3. When using an antenna, try to adjust it at multiple angles. If there is no signal at this location, you can place it in another area close to the outdoors or near a window. Find the best position and fix it. Do not change the position. 4. Do not use old-fashioned TVS. They can only be used on new-style TVS. Old-style TVS need to be used with digital set-top boxes. Old-fashioned TVS receive analog signals and cannot receive digital signals. Set-top boxes are needed for conversion. Generally, 4K, 1080P, 720P and ultra-high-definition TVS do not need set-top boxes, while other TVS do. A. Channels cannot be found at all. This category can be divided into several customer groups. The signal is not supported (signal not supported is usually in remote mountainous areas or suburbs, strong magnetic fields, where the signal is not open or there is strong magnetic interference, and all antennas are not working. Generally, the mobile phone signal of such customers is also very poor). The usage method is incorrect (the customer did not connect properly or the signal amplifier was not used). Or it can be tested in a single place. You need to search from multiple directions to find a relatively suitable place to fix the antenna and do not move it. The ground wave antenna is the signal emitted by the signal base station, which spreads in a circular pattern in all directions. It is different from Internet TV. Each point has its own signal strength, just like the FM/AM radios we used back then. This needs to be clearly stated in the listing or marked in the FAQ. B. Channels were found, but there were few. (Ground waves all search for open TV signals, which is different from the satellite receiving function we use. Satellites come with automatic decoders, and the working principle is completely different. However, in developed countries like the United States, TV signals are all open, so ground wave antennas are more suitable.) It is necessary to search from multiple directions to find a relatively suitable place to fix the antenna and then do not move it. Generally, placing it by a window or outdoors works best. It is better to stand the antenna upright and keep it away from magnetic products. C. If the search distance is insufficient, the gain is inadequate, snowflakes appear on the screen, or the display is unclear, it is usually because the antenna is not properly connected to the TV. Test it from multiple angles. In this case, the signal is open, and it is generally a problem with the antenna. Do not use old-fashioned TVS. It can only be used on new-style TVS. Older TVS should be used with a digital set-top box. Old-fashioned TVS receive analog signals and cannot receive digital signals. They need a set-top box for conversion. Generally, 4K, 1080P, 720P and ultra-high-definition TVS do not require a set-top box, while other TVS do.
