1: Do not use fake antennas (the quality is not guaranteed), and if there is a diamond antenna, you can use the association antenna. Ensure that the antenna has a standing wave ratio below 1.5. And it is very suitable to ensure that the reactance is matched. 2: The antenna cannot be used upside down. After being down, it stays in waves and destroys the machine. 3: The antenna cannot be pushed into the room for use, and it will also cause high standing waves. I also hate the human body. 4: Try not to always have an antenna, which will cause poor contact over time to produce high stay waves, which will affect the life of the machine. 5: When it is raining, pay attention to the joints not to enter the water, if the water enters, the standing wave height will be permanent. Also pay attention to the inspection of the joints at ordinary times. Is there any loose condition? 6: Frequently check the feeder outlet car end, there is no accident, if the disconnection intention fails, because it will cause the appearance of electric waves, permanent waves, and endanger the human body. If it is 100%, it can't be launched. 7: Bicycle transmission or short-distance communication power will also increase the life of the car. It is also good for your health.
