UHF RADIO FREQUENCIES

---

The UHF or Ultra High Frequency Band is from 300MHz-3GHz.Some website's definition the Military Airband is VHF and by another It is considered UHF.  For the purpose of this website we are considering the Military Airband (225MHz-400MHz) to be UHF because it s usually referred to as UHF Aero. UHF can be broken down into several smaller segments or bands of frequencies.

The UHF Band  Frequency Bands are as follows:

• Military Airband or UHF Aero is from 225MHz-400MHz
• SARSAT (Search And Rescue Satellite Aided Tracking) is used for locating EPIRB(Maritime personal locator beacons), ELTs(Aviation), and PLB(Land based Personal Locator Beacons) on the 406Mhz frequencies.
• Military & Government use 400MHz-420MHz
• Amateur Radio 70cm Band is from 420MHz-450MHz
• The UHF Business Band is from 450MHz-470MHz.  In this band there is Business, Law Enforcement, Fire Departments and EMS.
• FRS or Family Radio Service is in the 462MHz and 467MHz frequencies and shared with the GMRS or General Mobile Radio Service. Each service has its own specific set of rules.
• GMRS or General Mobile Radio Service is in the 462MHz and 467MHz frequencies and shared with the FRS or Family Radio Service.  Each service has its own specific set of rules.
• UHF Low Band TV Channels 14-20 and Public Safety Land Mobile Radio share 470MHz-512MHz
• Medium-band TV channels 21–36 use 512MHz-608MHz
• TV Channel 37, Radio Astronomy and wireless medical telemetry uses 608MHz-614MHz
•  Mobile broadband has taken over 614–698 MHz which used to be TV channels 38–51(frequencies were auctioned off in April 2017)  TV stations were relocated by 2020.
  • 617–652 MHz: Mobile broadband service downlink
  • 652–663 MHz: Wireless microphones (higher priority) and unlicensed devices (lower priority)
  • 663–698 MHz: Mobile broadband service uplink
• TV channels 52-69 used to use 698–806 MHz  These frequencies were auctioned off in March of 2008.  After the transition to digital TV broadcasting on June 12, 2009 bidders got to use the frequencies.  In 2021 these frequencies were modified for Next Generation 5G UHF transmissions for 'over the air' channels 2 thru 69 (virtual 1 thru 36).
• TV channels 70-72 used to occupy 806–816MHz.  Public safety and commercial LMR (Land Mobile Radio) now occupy these frequencies since 800MHz rebanding from 2005-2021
