You've missed the point, as I stated earlier!
I use an antenna tuner also. An old Johnson Matchbox.
Yes, it indeed will raise up a very week signal which may not
even be audible without a tuner. What is occurring is that the tuner
will facilitate the transfer of energy from a large impedance (Z) mismatch
between the
antenna and the receiver when the receiver is tuned far off from the
antenna's
resonance frequency.
The drawback is that you will have to "tune" the tuner each time you change
bands.
It has nothing to do with static and noise. The tuner will simply optimize
the signal transfer
, including noise, between the antenna/feedline and receiver. Sometimes
this is all that may
be required to "hear" the signal which otherwise would be completely lost
from the large
impedance mismatch.
Yep, you got it!
