Keep in mind that a BOG antenna really needs some kind of return (RF ground). That could be a few radials buried just below the surface of the earth (to minimize pickup from unwanted directions on the radials themselves). Otherwise, the return is in the form of common-mode on the outside of your coax's shield.
If it's not terminated, then a ground at the far end could be dispensed with. BOGs and associated grounds have been discussed at length here. I suggest you search back through the Topband archives. Lots of good advice there! Pay particular attention to threads containing Guy Olinger's posts on this subject.
