FM、VHF、UHF's frequency range
2023/02/10
a. FM wireless microphone: commonly known as FM, it refers to the FM 88-108MHz international FM broadcasting band. Early consumer wireless microphones used FM radios for reception, with simple systems and low costs. However, due to the effectiveness of their use, they could not meet the requirements of professional quality. In the 21st century, they could only become toys for children or students.
b. VHF wireless microphone: It can be divided into two types: low frequency and high frequency. The former uses the VHF50MHz frequency band, but due to its low frequency and long antenna length, it is most susceptible to interference from various electrical clutter. Therefore, this type of product has been replaced by the high frequency band in the 21st century and gradually disappeared from the market. The latter uses the VHF200MHz frequency band, and due to its high frequency and short antenna, it can even be designed as a hidden antenna, which is convenient, safe, and beautiful. The interference from electrical clutter is greatly reduced, and the circuit design is extremely mature. The price of parts is low, making it a popular model in the market today.
c. UHF wireless microphone: Use a wireless microphone with a frequency of 300-3000M. It is the mainstream of microphone applications in the 21st century. Due to avoiding interference from V-segment walkie talkies, stability has been greatly improved
