What is the difference between UHF and VHF Radios?

What is the difference between UHF and VHF Radios?

UHF stands for “Ultra High Frequency” while VHF stands for “Very High Frequency.” UHF can range from low band (378-512 MHz) to high band (764-870 MHz) while VHF ranges from low band (49-108 MHz) to high band (169-216 MHz). MHz stands for Megahertz and measures the speed of electronic devices.

What is UHF and VHF?

In the United States, the frequencies used for these systems may be grouped into four general bands or ranges: low-band VHF (49-108 MHz), high-band VHF (169-216 MHz), low-band UHF (450-806 MHz), and high-band UHF (900-952 MHz). VHF represents “Very High Frequency” while UHF represents “Ultra High Frequency.”
