Effect of a Simple Ground Screen on the Inverted Vee

The efficiency theory suggests that a larger ground screen or set of parallel wires is more effective than a single reflector wire. The idea is to create a large planar reflector, as opposed to a single reflector wire. Another way to say it is that the goal of the reflector is to improve the local ground conditions in the largest area possible.
