Antenna Polarity

• Polarity is a product of the design of the antenna.

• Each end must match.

• It can be used to minimize multi-path and interference.

• Typical Polarities:

  • Horizontal
    • Avoids multi-path from vertical objects like buildings
  • Vertical
    • Avoids multi-path from horizontal objects like the ground, bodies of water.
  • Circular
    • It can avoid multi-path from “odd-number bounced sources.
    • Left or right handed
