Topband: BOG... / partial BOG

[Dave NØRQ]

What about a Beverage that is a partial BOG?

I need to either go over a driveway, at 15-16 feet
(5 meters) up, or lay it on the ground for 10 to 15 feet.
Which would be better (or least bad)?
Also, if on ground, I'm assuming it should be insulated
wire.

Thanks.
