Don't worry about the noise.

Construct the best possible setup you can. Pay close attention to
matching the impedance to the receiver. Use quality/high-freq
semiconductors, even better than required/stated--if possible, keep
those noise figures low. Remove the antenna away from any potential
noise source as you possibly can. Keep the antenna as high as you
possibly can. Place the antenna where it will get the largest possible
view of the heavens/horizon. Use as Hi-Q coil/cap as you can, to narrow
the bandwidth as much as can be logically tolerated. Keep the
coax/feeder as short as is logically possible and the run away from
noise sources. Etc. ...

Now, worry about what you can do to help with noise reduction ... if you
find you have too much gain, drop a gain control in ... filters?
