The frequency range of wireless microphones is mainly divided into three types: FM, VHF and UHF.
FM wireless microphone: The frequency range is between 88-108MHz, usually higher than 108MHz, so it will not be interfered by FM radio stations.
VHF wireless microphone: The frequency range is 170-260MHz, divided into low-frequency and high-frequency bands. Low-frequency bands (such as 50MHz) are gradually being eliminated due to their low frequency, long antennas and easy interference from electrical appliances; high-frequency bands (such as 200MHz) are still used despite shorter antennas and reduced interference.
UHF wireless microphone: The frequency used is 300-3000MHz, usually between 400-830MHz. The 800MHz band (740-830MHz) is currently the most popular UHF band because it avoids interference from V-band walkie-talkies and has higher stability.
