Overview of the Outdoor Installation

Antenna Polarization

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.
