What is the polarization of the antennas?
Radio waves are made up of two components: an electric field and a magnetic field. The polarization of the antenna depends solely on the direction in which the electric field (E-lines) propagates. When an antenna is mounted vertically, the E-lines will be strongest perpendicular to the axis, and will propagate out parallel to the antenna and perpendicular to the earth’s surface. This is called vertical polarization. When an antenna is mounted horizontally, the opposite is true; E-lines will propagate out perpendicular to the antenna and parallel to the earth’s surface. This is called horizontal polarization. All Valcom whip antennas are mounted vertically and thus exhibit vertical polarization in the azimuth plane.
