This is a very long piece of wire, but if you have the room it will yield a
remarkably selective receiving pattern.  A two-wire beverage of the same length
will have the same pattern and allow you to reverse the directionality, as well
as steer the rear null by adjusting the termination in the shack.  Note how the
rear null extends over quite a range of elevation angles.
