Below Figure 32 to Figure 40 show DD of the Beverage Antenna at the 160, 80, 40, 30, 20, 17, 15, 12 and 10- meter Bands in the vertical plane. Feedline with matching transformer is on the left side and the termination resistor is on the right side of the figures.

 

As you can see from the Figure 32 - Figure 40 the DD of the Beverage Antenna with horizontal wire placed at height 4 meter above the ground looks better compare to my classical Beverage Antenna shown at Figure 1. However lost 12 and 10- meter bands and complexity with installation of the horizontal wire did not compensate the new antenna advantages.
