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
D.
WPA 2 encryption
Explanation:
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.
