MK,

The 'tuner' simply "Optimizes" the MATCH between the Receiver and/or
Transmitter and the Antenna and Feed-Line; since most 'tuners' are
near the Receiver and/or Transmitter.

Both Signal and Noise are transfered equally.

For 'noise reduction' look to modifying your Antenna, Feed-Line and
Ground [System] to maintain or improve your signal levels; and reduce
your noise levels.
