This interference can cause TV image distortion, , mesh patterns and sound distortion, etc., causing mosaics in the set-top box, and even damage to TV sets, set-top boxes and other electrical appliances. The isolation protector can the potential difference between the power grid and the cable TV network, improve the TV's viewing effect, and protect the safety of household appliances. All of the above reasons cause the TV cable to be . If the TV cable is not grounded well, high voltage electricity be transmitted to the user', forming a potential difference between the power grid ground wire and the cable TV network ground wire, causing ground interference. Cable TV cables usually share poles with power lines and telephone lines. After long-distance transmission, they may be induced by higher voltages, contact with leaking wires, or be induced by anti-thunder, which may cause the TV cables to be . Application introduction: This product is suitable for high-voltage isolation between cable TV home cables and TV sets or set-top boxes. Cable TV cables usually share poles with power lines and telephone lines. After long-distance transmission, they may sense higher voltages, contact leaking wires, sense anti-thunder, and may be connected to electrical equipment with leakage in some users' homes. If the TV cable transmits high voltage electricity to the user', this interference may cause distortion of the TV image, , mesh patterns, and humming sounds, etc., or even damage to electrical appliances such as and set-top boxes. Therefore, every TV needs to be installed. Don't lose the big picture because of the small details, and then regret it., Weight: 0.07826410301 pounds, Manufacturer: Damavat
