Low dipoles, like any receiving antenna, primarily developes S/N
ratio by antenna pattern.
In order to improve S/N ratio, it has to have a higher response in
the direction of desired signal than undesired signals and noise.
If the noise is mainly arriving at very low angles and the signal at
high angles a low dipole can improve things, but like you I have
never found that to be true here. I'm sure there are cases where it
is true, but they would have to be cases with high local noise and a
comparison antenna that responds well to the noise. I just don't have
any local noise, so a low dipole is always a dog for receiving
anything more than a few hundred miles away at my QTH.
Your mileage may vary, and it doesn't hurt to try something. 73,
