Wireless Microphone Frequencies

Wireless microphones are split into two types - some are freely available for the public to use, but some require the purchase of an operating licence from Ofcom to use legally.


Do you need a licence to use your wireless microphones?

 

More About Licences

If your microphones are on any frequencies other than 173 – 175 MHz and 863 – 865 MHz you will need a licence to operate them legally.

As at Sept 2018, it's £28 per year per microphone for a fixed site indoor licence and £75 per year for a shared licence covering up to 10 microphones.
 

UK Shared Licence

VHF and UHF Shared frequencies can be used anywhere in the UK once licensed. The licence can also cover anyone hiring from the licencee.

Co-ordinated Licence

Co-ordinated frequencies are licensed at a specific site for short or long term. They provide the best protection against interference.


How to buy your licence


Ofcom control the licensing of wireless microphones and monitors. Their website is very confusing and it's sometimes easier just to call them! However, please click here for the correct section on the Ofcom website.
Please note that it is cheaper to buy online than to call them.

Alternatively you can contact the PMSE department as follows:

Should I buy wireless microphones with fixed or changeable frequencies?

Some UHF wireless systems offer tuneable frequencies allowing you to select your frequencies within a range.

This is a useful feature because you'll find that some frequencies work better than others in your area. If a frequency doesn't work well or has a lot of interference it can dropout, sound crackly, or even sound like it's underwater! Change a few MHz and it will be as clear as anything. See UHF tuneable frequency mics on our website


True Diversity

True Diversity means is that the transmitter sends two signals to the receiver on different frequencies which are then summed at the receiver end. This reduces the amount of drop-out or signal loss. If you have a wireless system that is not true diversity it could be prone to drop out.
