Hi Marcus, I hoped so, that is why I bought one ;-). I think the max is 73dB. The actual value I set with a slider is 90dB. Thus I am pretty much maxed out there. But like I wrote earlier, that is the only way to receive at least one station. Don't have good RF working conditions. Even cellular is a problem.
