Two-Way Radio Frequencies - VHF and UHF

To understand how two-way radios work, you will first want to become familiar with the term ‘frequency.’ Frequency is the wavelengths, which two-way radios work upon in order to transmit and receive messages. For example, two-way radios work between 30MHz and 100MHz , which are both frequencies.

Within the 30 MHz to 100MHz range of operation, there are 2 different categories of two-way radios: UHF and VHF.

VHF or “Very High Frequency” is the range between 30MHz -300 MHz. This range of frequencies are ideal for more line-of-sight communications where no obstacles are between the communication devices.

UHF or “Ultra-High Frequency” is the range between 300MHz and 100MHz (aka 1 GHz). UHF two-way radios are the most popular option of handheld devices and can communicate through walls and other obstacles such as buildings, trees etc.

Most handhelds reside within the 130-175 MHz range, though anything beyond 403 MHz is typically (though not always) expected to be licensed.
