I live in Canada and will be shooting a documentary in the UK this summer for which I need to use a couple of wireless lav mics. I have been looking at the Sennheiser EW112p series which seems ideal. However, I am not sure which frequency range to buy. While frequencies up to 600Mhz or so seem fine for Canada, the UK only appears to have 863-865Mhz available, license free. To use other frequencies, there is a charge and seems like it will add up fast.
Can anyone recommend a wireless lav that would be suitable for use on frequencies both in Canada and the UK?
