TWO WAY RADIO TRENDS & NEWS

VHF vs UHF : Which Type of Two-Way Radios Do You Need?

vhf vs uhf two way radio

This short guide is to settle any confusion you may have about two-way radios.  We are going to be discussing about what the difference is between VHF (Very High Frequency) and UHF (Ultra High Frequency) two-way radios.  This is because there is a big difference and that if you get muddled up then the consequences can be quite an annoyance.  Never fear though, we are here to help solve any confusion you may have.

What are the main differences between a VHF and UHF two-way radio?

There are two-way radios that can either use UHF or VHF.  Both prices are comparable, but their functionalities are not.  The main differences between these two types are the range of frequencies that they use.  VHF have a narrower spectrum and fewer channels than UHF two-way radios.  This is due to the long length of time they have been around for.  This can lead to congestion and greater chance of interference from other two-way radios in the surrounding areas.

UHF two-way radios have a much shorter aerial than VHF two-way radios which make them more aesthetically practical. UHF are better with overcoming obstructions.  However, they use more battery power than VHF two-way radios use due to their high frequency. 

When would you need UHF two-way radios?

  • Indoors: UHF two-way radios are best used for indoor use in buildings.  This is because they are better for overcoming obstructions.  This includes buildings, steel, wood etc.   They are also effective in muti-storey buildings
  • A mixture of indoors and outdoors: When you have a mixture of indoors and outdoors activities that you need two-way radios for, UHF are best as they are a great all-rounder as they have great coverage
  • Multi-storey buildings

When would you need VHF two-way radios?

  • Outdoors: VHF two-way radios are best suited for outdoors, where the signal can pass through objects easily.  VHF two-way radio signals tend to travel further, making them optimum for outdoors use across hilly terrains and large areas

Some other little nuggets of information

  • You cannot use a mixture of VHF and UHF two-way radios in the same system, it will not work
  • The VHF licence is easier to obtain in London due to most users being on UHF
  • VHF radios are operate on 5Watts and VHF 4Watts
