There are a number of important factors to consider when choosing between UHF (ultra high frequency) and VHF (very high frequency) wireless microphones, including where and how the system will be used, the number of systems needed, and the price. There are also several application issues that can affect the choice between UHF and VHF.


UHF and VHF have different names because they operate in different bands of the FM spectrum. UHF systems do not hold any large technical advantage over similar VHF systems. However, interference due to electrical equipment, digital devices and other electronic equipment is generally lower at UHF frequencies. This is because noise from these sources becomes less intense as the frequency increases.


UHF wireless systems operate in the 470 mHz to 698 mHz bands. The so-called 700 mHz band — between 698 and 806 mHz.


These systems have strong output and they may also be preferable if high-performance antennas mu
