Frequency Asked Questions

Frequency Asked Questions

We are often asked about available radio mic frequencies in the UK. Here’s a bit of info in the hope of shedding some light:

It can be simply broken down to two sections. 1. License exempt frequencies. 2. Licensed Frequencies.


1. License Exempt Frequencies:

  • 863MHz to 865MHz – The License free frequencies are available in UHF (ultra high frequency) –
    Within this range you’ll be able to use 4 frequencies and transmitter power is limited to 10mW ~ 50mW on belt pack transmitters.
  • 163.5Mhz to 180Mhz – all low powered devices are exempt from licensing. Mandate UK11. According to Ofcom’s Interface Requirement IR2030.
  • 2.4GHz to 2.483.5GHZ – Wifi band
    We often see this being used by some digital transmitters and brands such as Zaxcom, Timecode Systems, Sennheiser, etc.

Ofcom describes the low powered devices as – ‘A Short Range Device (SRD) is a general term, applied to various radio devices designed to operate usually on a license exempt basis, over short range and at low power levels. This includes devices such as alarms, telemetry and telecommand devices, radio microphones, radio local area networks and anti-theft devices with maximum powers of up to 500 mW at VHF/UHF, as well as certain microwave/Doppler devices with maximum powers of up to 10 W.’

2. The Licensed Frequencies – ‘Shared License frequencies’

Since the DSO (digital switch over) in 2012 we are now confined to using Channel 38 – 606 to 614MHZ.
You need a license to operate in Channel 38 or you will run the risk of being fined.
Licenses cost £80 for 1 year, £155 for 2 years. If bought on line they are slightly cheaper – £75 & £135 respectively.
