UHF Bands

UHF, or Ultra High Frequency, is the next higher frequency range to VHF, within the radio spectrum. UHF equipment operates in the frequency range from 300 MHz to 3000 MHz (3 GHz); however, in the context of land mobile radio (LMR) usage, "UHF" primarily refers to one of two frequency bands, UHF1 / UHF R1 (UHF Range 1) and UHF2 / UHF R2 (UHF Range 2). More recent LMR UHF bands include 700 MHz, 800 MHz, and 900 MHz. In addition to LMR usage (which includes Federal and business users), more recent UHF uses include digital TV, Global Positioning Systems (GPS), Bluetooth, cellular and cordless phones, the Family Radio Service (FRS) and WiFi. UHF1 and UHF2 radios came into usage following WWII. 7/800 MHz radios came into usage starting in the 1970's and 1980's, primarily to support APCO (Association of Public-Safety Communications Officials) Project 25-compliant Trunking systems, which allow for better equipment interoperability between different radio manufacturers.

The UHF Bands are as follows:

• UHF1: 380 – 470 MHz*

• UHF2: 450 – 520 MHz

• 700 MHz: Rx / Tx: 764 – 776 MHz

Tx Only: 794 – 806 MHz

• 800 MHz: Rx / Tx: 851 – 870 MHz

Tx Only: 806 – 825 MHz

• 900 MHz: 896 – 941 MHz
