Uhf frequencies Because uhf (ultra-high frequency) is used, the by-wm6s can be used for both outdoor and indoor activities. uhf is less sensitive to interference than vhf (very high frequency). electronic devices, metals and obstacles such as walls, ceilings and windows can have a negative influence on the signal. with a uhf set the chance of this happening is smaller and it is also possible to bridge a larger distance than vhf.
