I think you're misinterpreting something here but that's reasonable since I haven't presented the total picture of the layout in some time. We use BOG's of between 500 and 800 feet. The phase wire is, IIRC between 100 and 150'. The latter has been the same length 5 years in a row. We have used up to 1400' once. We have found that the npoint of diminishing returns for this location is between 800' and 1000' in the sense that we notice no improvement at all at lengths beyond 1000'. The logistical issues with running that long are numerous as that forces us to cross another vehicle path used by 4WD's where it's nearly impossible to bury the wire so as to prevent it being dislodged and broken.
