Hello. I want to purchase a Sennheiser Evolution G2 100 Series UHF wireless lav mic system, but don't know what frequency to order. Is there a way to find out what frequency I should be using in my area? What about shooting in other locations around North America? Are there frequencies I'm not supposed to be using or ones that will work better for a given area? I don't know much about this so if someone could point me in the right direction it would be greatly appreciated.

Thanks!
