Should I Use Vhf or Uhf?

The quick answer is: choose VHF if you plan to only use the radios outdoors and in an area that is relatively free of obstructions, such as buildings. If you plan on using the radio indoors, both indoors and out, or outdoors but around buildings, choose UHF.

Do walkie talkies use VHF or UHF?

UHF and VHF are the two most commonly used frequency ranges for walkie talkies. VHF features 130-174 megahertz, while UHF features 400-520-megahertz. These higher frequencies can travel in straight lines that are called line of sight signals, unlike frequencies that are below two megahertz.

Can you use VHF antenna on UHF?

Unfortunately it's not possible to convert VHF to UHF etc, as each type of radio contains hardware that enable it to operate on a specific frequency range. If you're buying or hiring more radios to work alongside ones you already use, they need to be of the same type.
