The wide range of wireless systems available can be confusing. To help you choose the best wireless mic system we have only listed systems that we have used ourselves. We have either installed the radio mic systems for customers or operated them at events.
We recommend buying high quality uhf wireless microphone systems. We have handheld microphones, headset mics, and lavalier microphones.
Dual wireless systems include two receivers in one physical unit. Quad wireless systems have four receivers in one unit.
After the list of wireless systems below there is a section containing useful information about wireless microphones.
Radio mic frequency ranges in the UKOver the recent years competition for available wireless spectrum has increased dramatically. The UK government decided to clear large numbers of frequencies previously allocated to wireless microphone users.
This has affected both professional broadcasters, performance and music professionals, together with churches and occasional users.
The table shows uk wireless spectrum avaialable for shared usage, the frequencies can be shared by anyone throughout the UK.
Consultations on clearing the interleaved spectrum are ongoing.
|Wireless Microphone frequencies for UK|
|Channel||Frequencies||Licensed||No. of Mic's|
|VHF||173.8 - 175 MHz||none required||2|
|Ch 38||606.500 - 613.500 MHz||£85 per year (2019)||10***|
|Ch 70||863 - 865 MHz||none required||4*|
|Digital||2400 - 2483.5 MHz||none required||10**|
* Although 4 systems are possible, in practice it may be limited to 3 in close proximity to mobile masts
** Up to 10 channels are possible, the max number may be limited in close proximity to wireless data networks
*** Offcom have a 10 channel plan that shows 10 mic's can be used concurrently, some manufacturers say they can provide more
Channel 38 systems require a licence
Which wireless microphone frequency is best?
We have installed many wireless microphone systems, and have experience with using all 4 frequency ranges.
VHF is so prone to interference that we do not recommend it for any purpose.
Channel 70 remains popular because it is free, however the government can close it down with only 12 months notice. It is also sandwiched between mobile phone frequencies. Because of this we advise against using it.
Channel 38 is the only choice for radio mic systems that you rely on to provide a service. The High quality equipment is reliable and the signal quality is much better. The government only offered compensation to licence holders when it last moved the wireless mic frequencies.
Digital wireless technology appeared to offer a way forward for users who needed more than 10 concurrent microphones. However, they share the same frequencies as IT Wireless Networks. Where there are large numbers of WiFi networks or large numbers of microphones the WiFi networks will get disrupted.
Our engineers strongly recommend buying a license and using Ch38 equipment
What type of wireless mic should I use?
Headset microphones are becoming increasingly popular as they are available in discrete skin colours and smaller sizes. A wireless headset allows the wearer to turn their heads and interact with the surroundings without loosing reception on the mic.
Handheld microphone systems are common at press conferences and presentations as they offer a practical way of picking up questions from the audience. For an audience not used to handling microphones you should supervise the use of handheld transmitters.
