The dipole antenna, which is the basis for most antenna designs, is a balanced component, with equal but opposite voltages and currents applied at its two terminals. The whip antenna is a monopole antenna, and like a vertical dipole has an omnidirectional radiation pattern, radiating equal radio power in all azimuthal directions (perpendicular to the antenna's axis), with the radiated power falling off with elevation angle to zero on the antenna's axis. Working principle. Figure 7.1 illustrates operation of a basic half-wave resonant dipole antenna. Monopole antenna also belongs to the linear antenna category. This is usually not so severe to make the antenna unusable, and may be considered a reasonable compromise for the dual band coverage. In fact, it means that the rule is wrong, but due to wildcard (pattern) rules make cannot determine what exactly caused the issue.
