Going a step
Most "receiving" antennas for 160m including Beverages actually result in less
signal at the receiver compared to "transmitting" antennas, however recieving
antennas have _much_ lower noise.As you alluded to the name of the game for
receiving is to improve the signal to noise ratio, so a
May want to browse the W8JI website for a lot of interesting information on
all phases of ham radio.
Here's a link to the Beverage antenna section:

Have a look at his antenna comparison spreadsheet to get an idea of
performance of various receive antennas.
Hi Glenn, I've only been using Beverages on 160m for 40 years, so this
is a somewhat partial and subjective view, but they certainly increase
the S/N ratio considerably for human ear reception of extremely weak
signals *when terminated correctly*. Usual gain is around -20 dBi, but
irrelevant
I use JT4G on 10 GHz, but after a reboot, the mode now resets to A every
time. It used to start in the same sub-mode that was last used when I
closed the program. Closing the program, then reopening without a
reboot shows correct behaviour, but then after a reboot, it goes back to
JT4A the
When they built and installed the beverages they noticed they
had just as much noise as the other antennas if not more.
I modeled the Beverage and discovered it was a very high
loss antenna. The soil was the lossy element and if you
tried to reduce the loss by tuning the termination and
matching

A beverage antenna will often produce weaker signals than, say, an inverted
L.
However, it will decrease the noise on the signal, and make it easier to
copy, which
should make it easier to decode.

This is a theory question. There is a bit of FT8 on 160m. Does use of a
Beverage Antenna to get more signal raise the S/N value? Would that
antenna help with receiving weaker signals (a variation of that S/N
question)?
