Table 1. Frequency range and band designator.
To illustrate vertical wave polarization, imagine a rope lying reasonably straight on the
ground. One end is attached to a tree or other support (Figure 1-2). If the loose end of the
rope is raised, tightened, and given a violent up and down motion, a series of undulationing
waves will travel along the rope. The movement of the waves will be vertical to the earth and
If the same rope had a similar movement applied in a horizontal manner, the waves would be
in a horizontal plane. These waves would be called horizontally polarized (Figure 1-3).
