Isn't BOG still a beverage just with more ground coupling loss because its
literally "on the ground"? So the typical answer on beverages seems to be
that 4 - 10 ft above the ground is low enough to eliminate the undesired
noise but high enough to reduce the losses from being too low to the ground.
A BOG is a beverage with higher than desired losses. But if its long
enough, pointed in the right direction, and your ground conductivity is
accommodating, its less of a trade than the reverse of those items.
I have had a few unplanned BOGs that were discovered as "on the ground"
because of some supports falling down. I could immediately hear the
difference, but they still worked. Would they be usable if that was my only
option? Sure. Just not as good as the same wire at 6 - 8 ft.
I use 650 - 1000 ft terminated beverages and they are quite amazing. My
ground condition is lossy and I don't have much local noise to null out.
Its pretty much all atmospheric noise.
