VHF and UHF radios: What's The Difference?
VHF radios transmit on frequencies around 146 - 174MHz (wavelength around 1.8 - 2 metres)
UHF radios transmit on frequencies around 420 - 470MHz (wavelength around 0.6 metres)
VHF versus UHF - Difference In Practical Terms
The first thing to realise is that for many short-distance applications for walkie-talkie radios, both VHF and
UHF radios will work just fine.
However, VHF radios will in general transmit a bit further than UHF radios in open conditions, for the same
UHF radio signals will usually penetrate and propagate better inside buildings than VHF radio signals.
Test Radios To Make Sure They Will Work In Your Location
The above is a very simple "rule" - that VHF is better for outdoor, open conditions and UHF is better for use
within or between buildings.
Reality is more complex than this - in some buildings, depending on the materials used in the construction, VHF
waves will go through some walls better than UHF.
It pays to test radios out in the intended location before an event or occasion where you must rely on them.
If you want to try out a couple of our radios in your premises with a view to purchasing some, or if you want to
test if they will cover the site of an event for which you want to hire some walkie-talkies, please contact us and
we can usually arrange this.
