What is the Difference Between UHF and VHF Wireless Systems?

The main difference between the two systems is the broadcast frequency range.  The available radio spectrum for UHF wireless system use is eight times greater than for high-band VHF.  Ultimately resulting in a larger range and the ability to run multiple systems.  If your setup is very simple and less complex, VHF should be more than enough to complete basic vocal tasks.  If your setup requires multiple wireless units and you play in crowed radio environments choose UHF.
