What Are the Advantages of Using the UHF Band?
Although wireless systems are available in both VHF (175~215MHz band) and UHF (600~1000MHz band) models, the increasingly crowded VHF bandwidth is causing more and more problems with interference from other VHF frequency sources. Consequently, many professional wireless microphone system users are progressively moving to the UHF band. In addition, many UHF systems are PLL-synthesized “frequency-agile” for even greater flexibility and ease of use. PLL-synthesized designs having tens of channels pre-set will allow users to switch to a pre-set frequency of their choice and make more non-interfering channels available for quick selection, thus helping to avoid interference problems. UHF systems are more complex in manufacturing than VHF models and are therefore more expensive, but their greater capabilities make them the recommended choice for any professional wireless application today.
