Doug,
Just try to get as much wire in the vertical plane as possible. The vertical
section can have a nearby second shorter parallel vertical section called a
linear load or a horizontal linear load wire near the ground. The linear
load is allot less lossy than a base loaded coil. I discuss linear loading
on my antenna websites at http://www.kn4lf.com/kn4lf52.htm and
http://www.kn4lf.com/kn4lf2.htm .
