Polarization of the wireless antenna is the orientation of the wireless signal with regard to its coverage both horizontally and vertically. Polarization can be vertical, horizontal, circular or combinations of these.
The E-plane and H-plane are reference planes for linearly polarized antenna.
This diagram below shows the relationship between the E and H planes for a vertically polarized omni-directional dipole antenna
This type is intended for short range meshed networks:
within its range.
