What are the different VHF and UHF frequencies?

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 = “Very High Frequency”. UHF = “Ultra High Frequency.”

What is a UHF TV?

UHF television refers to the use of ultra high frequency radio to broadcast to your television set. This type of frequency can be used for both digital and analog broadcasts, and the VHF frequency band runs from 50 MHz to 225 MHz.

These frequencies are not generally legal outside of the U.S. or Canada. The larger part of the high-band VHF region is 174-216 MHz. The primary users of this band are VHF television channels 7 – 13. Each occupies 6 MHz of bandwidth: channel 7 (174 – 180 MHz); channel 8 (180 – 186 MHz), etc.

What is the difference between the VHF and UHF ham bands?
