Try without an active one first. I once did a radio art piece at Serralves museum with a usb-powered soundcard and FM transmittor with a normal extension, in a vertical pole (7 meters high), we used a 10 meter usb extension we bought on FNAC or something like that. 

:)
Although at the time we wondered if it would function, (since a lot of sites and I think wikipedia himself states that it would need a power hub in the middle), but it worked.
