 UK legal radio mic frequency guide

When using radio microphones it is important to use the right frequencies. There are different sets of frequencies suitable for different purposes. Some require a licence while others do not. The following information gives a brief guide to find the most appropriate solution.

Licence exempt frequencies – No licence required

These frequencies are available throughout the UK, indoors or outdoors, without a licence. There is availability at VHF and UHF and the frequencies are detailed below.

All new equipment should use the following frequencies:

VHF band (173.7 – 175.1 MHz)                 UHF band (MHz)

173.800      174.000      174.200      174.400      174.600      174.800      175.000              863 – 865

Notes

Typically, up to 3 VHF frequencies can be used together. For example, 173.8, 174.2 and 175.0MHz.

Typically, up to 4 frequencies can be used together. For example, 863.1, 863.7, 864.1 and 864.9 MHz.

Transmitter power: 10mW (Up to 50mW permitted for body-worn pack).

VHF other users:   Wireless microphones only.

UHF other users:  Wireless microphones, domestic cordless headsets and loudspeakers.

Older VHF equipment may continue to use the legacy frequencies:

VHF band (173.7 – 175.1 MHz)

173.800      174.100      174.500      174.800      175.000

 

Wi-Fi band (2400 – 2483.5 MHz)

Wi-Fi Band (MHz)

2400 – 2483.5

Notes

Manufacturers claim up to 70 frequencies can be used together.

Transmitter power: 10mW.

Other users: Wireless computer networks (Wi-Fi), RF Tags (RFID), Bluetooth short-range links, video links, wireless microphones, microwave ovens, movement detectors, industrial control and monitoring, wireless DMX control, digital wireless intercom.

Licence exempt summary

There is the potential for interference from other radio microphones. You may find that licence exempt frequencies suit your purposes - but if you want to reduce the likelihood of interference, shared or co-ordinated frequencies may better suit.

Shared licensed frequencies – UK roaming

Co-ordinated licensed frequencies – for specific UK locations

Regardless of whether you use licence exempt or licensed radio microphone frequencies, multiple radio microphones used at the same location can interact and interfere with each other. This is known as intermodulation. Take particular care which frequencies you use together to avoid these problems.

This document gives only brief details of the frequencies available for radio microphones and the licence fees that apply. Further information can be found by setting up a user account and logging onto the Arqiva PMSE website www.pmse.co.uk.
