In the USA, the available frequency ranges are:
●
The entire UHF TV band (470-608 MHz)
●
The 600 MHz guard band (614-616 MHz)
●
The 600 MHz duplex gap (653-663 MHz)
●
The 900 MHz ISM Band (902-928MHz)
●
The 950 MHz STL Band (941.5-960 MHz)
●
The 1.5 GHz AFTRCC band (1435-1525 MHz), with an appropriate license.
In the UK, the available frequency ranges are:
●
The core UK UHF TV band (470-702 MHz)
●
The 800 MHz duplex gap (823-832 MHz)
●
The 800 MHz guard band (863-865 MHz)
●
The DME bands (961-1015 MHz, 1045-1075 MHz, 1105-1154 MHz), with an appropriate license.
