VHF wireless microphones are utilized mainly in the 170-200 MHz band range. The UHF is mainly used at the 500-900 MHz band.

Presently, the VHF range is saturated due to a large number of users. It is worsened with excessive self-interference signals and other types of electrical RF interference. Consequently, the professionals tend to use the UHF ranges. Additionally, the PLL Synthesized frequency agile feature allows multi-channel agility. It avoids interference caused by other RF signals and electrical appliances to assure better performance.
