• Question 351:

  A technician has low signal strength connecting two wireless bridges. Which of the following could be the problem?

  A. Low PoE wattage
  B. Opposing antenna polarizations
  C. Short distance between antennas

  ---

  The polarization of an antenna is the orientation of the electric field (E-plane) of the radio wave with respect to the Earth's surface and is determined by the physical structure of the antenna and by its orientation. It has nothing in common with antenna directionality terms: "horizontal", "vertical", and "circular". Thus, a simple straight wire antenna will have one polarization when mounted vertically, and a different polarization when mounted horizontally.
