This is highly dependent on how much gain your active antenna provides, 
how much feedline loss you have, etc.  Since the signal level is pretty 
constant, I would increase the gain at least until the broadband noise 
is at least about +/- 1000 ADC counts.  That will still give you 24 dB 
of headroom
