About antennas

Antenna funtionality is characterized by Frequency Range, Gain, Directionality, Angle, and Polarization.

Antenna Angles

  • Antenna polarization is determined by the direction in which the electrical component 'E' of the RF signal oscillates as it propagates through space. If 'E' oscillates in a single plane, the antenna is classified as 'linearly polarized.' If E rotates through space, the antenna is classified as 'circularly polarized.' The polarization of the transmitting and receiving antennas must match to establish a link. Polarized antennas reject RF distortion/fading caused by RF multipath issues, which is a complex phenomenon typically caused by the presence of significant metal structures near the antenna. Storage terminals, tanks, and refineries are examples of facilities where Syscor relies on circularly polarized antennas for establishing reliable RF connectivity.
