Yes, unless you use VHF equipment on the licence-exempt channels 173.8, 174.1, 174.5, 174.8 and 175.0MHz. You can use up to four of these together, 174.8MHz is generally left out as it tends to interfere with one or more of the others. Your equipment must have a maximum radiated power of 10mW for both handheld and lavallier transmitters.

As a hire company, we have both UHF and VHF shared frequency licences which cover 14 channels in UHF Ch69 and 15 channels in the VHF spectrum, 11 of which can be used together. These cover equipment up to a maximum radiated power of 10mW for handheld and 50mW for lavallier transmitters.
These licences are used by our customers and the cost of them is built into the hire charge. You should get an SAP3 form to confirm that you can use these frequencies.

If you require more than this number of frequencies, it is possible that the venue you are using has a licence for some that can be used with the shared frequencies. Otherwise, you will need to contact JFMG (the Joint Frequency Management Group) to obtain more licences. Their number and other details are available on our links page. If you are hiring from us, we will undertake to organise this for you if you wish.
