[amsat-bb] Best pre-amp for Mode S

["Karl Sandstrom" <k5man@xxxxxxx>]

I am in the process of building my AO-40 receive station and am considering
the purchase of a DB6NT pre-amp to complement a Cal-Amp downconverter (50db
gain) and a 90 cm dish.  The folks at DB6NT offer a single and dual stage
pre-amp.  They have 15 db and 35 db gain, respectively.

Are there any thoughts on which one would be better for this installation?
Is there such a thing as too much gain?
