I don't really know the technical reasons
for this, but it makes sense that a big antenna will deliver a more
robust signal than a smaller one will.
It's all about the aperture of the antenna.
Even though the larger antenna has a less-tight F/B or forward lobe, the
fact that it is physically larger means that it is coupled into a
greater area of space. So it has a larger aperture.
Because of this, i.e. it's coupling into a larger physical area, it can
average out the effects of ionospheric refraction of the signal, fading,
etc. over a larger area. This often is perceived as a better signal, or
a steadier signal.
Hope that made sense.
