Antenna Polarization 2
Radio waves emitting from a Yagi antenna are linear, leaving the
antenna in the same plane as the antenna elements.
• When the elements are positioned
up and down
, the radio
waves are
vertically
polarized.
• When the antenna elements are positioned
left and right
, the
radio waves are
horizontally
polarized.
Vertical polarization is standard for the RoamAbout 14-dBi
Directional Antenna.
With RoamAbout outdoor antenna products, it does not matter
what type of polarization you choose, as long as the antenna at
one end of the communications link is mounted in the same plane
as the antenna at the other end.
In some cases you might decide to mount the antenna for
horizontal polarization. For example to minimize the influence of
cross-talk between antennas when:
• Multiple antennas are mounted on the same antenna mast.
• Your wireless link transmissions cross another radio beam
from a neighboring installation.
