WIlliam,
ITs missing a stage if you want to use 2n3904s at 10DB.? However if you use a higher frequency
(and likely a more costly) part that is not required.
Its about gain three stages at roughly 16DB is 48DB plus the finals.
Or you can do 5 stages at 10db each for 50DB and plus the finals.
What you cannot do is stages that start at 16db at 80M and fade to about
10-11db at 10M.? Its hard to get stable gain out of a device that is maxed out.
Doing that often icites instability and oscillation.
