True the lower velocity factor does bring the frequency down lower with
snow & leaves. In my case found that 215 feet may be best in the dry
month in summer, 200 feet is best on 160 meters year around. I can
get 3 S points front to back on my two wire reversible BOG under deep
snow, but it is considerably more F/B spring and fall.
In the summer it is usually my quietest antenna for working Europe at
their sunrise. There is 160 meter DX all seasons if anyone wants to go
after it.
Remember when you work Africa, Australia, New Zealand, & South
America in winter, it is their Summer.
Many have a tendency to go too long on the BOG antenna wire

Not based on my experience with BOGs and LOGs under significant snow, or
too many seasons of falling leaves, or both. One thing that happens is
whatever original BOG tuning, setting up good f/b, done with nothing on top
of it, gets really skewed as the velocity factor goes lower and lower,
under more frozen water, leaves, whatever.
BOGs deliver a lot less signal than regular beverages, and most often need
an amplifier or a good preamp in the rig to bring the signal up to useful
levels.
