text: A typical monopole antenna has an omnidirectional radiation pattern; it radiates equal radio power in all azimuthal directions perpendicular to the antenna axis, with the signal power decreasing with elevation angle to a null (point of zero radiated power) at the zenith.
text: Quadrant antennas produce mostly horizontal polarization at low to intermediate elevation angles and have nearly omnidirectional radiation patterns.
