Yes I know the difference between bias power and RF gain, so I misunderstood the Shure specifications...

I understood that an amplification was necessary to compensate the loss of the "bias voltage" for longer cables, the voltage necessary to power the antenna!
Anyway I can't understand why the Uabiast is able to feed the antenna through a 30 feet coaxial cable but not with a 100 feet cable.
I'll check again the bnc connections.
Thank for your answer!
