Early mobile phones had a long external antenna, but with the advancement of technology, the antenna was transformed from an external to an internal hidden antenna through industrial design, which can effectively communicate. The function of the walkie-talkie is mainly the communication function, so its most important thing is good signal Transmission and reception ability. Therefore, the requirements for portability and aesthetics are relatively low. In the process of communication, the walkie-talkie does not need to rely on the network signals of the three major operators, but only needs to have a receiver walkie talkie antenna. Its most important function is the communication function, so There are particularly high requirements on the appearance, the communication effect of the walkie-talkie will be much higher than its design, and the working frequency of the walkie-talkie is lower than that of the mobile phone, so it needs to use the Interphone antenna to transmit signals better. Therefore, both walkie-talkies and mobile phones use radio waves for transmission, but TWO Way Antenna is indeed different. In addition to their own frequency, it has a lot to do with their purpose and scene. FM AM Antenna What is FM AM antenna? Frequency modulation (FM) and amplitude modulation (AM) antenna is an antenna device for receiving FM and AM broadcast signals. FM signal has strong anti-interference ability and good sound quality, and is mainly used for high-quality music and voice broadcasting. AM signals travel a long distance, but are easily disturbed, and are often used in news and talk broadcasts. Different types of FM and AM antennas are designed according to the corresponding signal characteristics to optimize the signal receiving effect. What's the difference between automobile FM and AM antennas and ordinary FM and AM antennas? Automobile FM-AM antenna needs to adapt to the complex electromagnetic environment and high-speed motion state of the automobile. Roof antenna, shark fin antenna and other forms are usually used, which are waterproof, dustproof, wind-resistant and so on, and should be compatible with the electrical system of automobile body to reduce signal interference. Compared with ordinary antenna, it pays more attention to the integration with the overall design of the car and the signal receiving performance in dynamic environment.
