Antenna Alignment Guideline

Introduction
Pre-Alignment
BroadOne GX4000 Manual (R3.0) issue 1.03
One of the most important elements of a wireless system deployment is
the antenna system. Proper alignment of that antenna system is critical to
the performance of any wireless system. Engineering a wireless link for the
highest achievable system gain while minimizing or eliminating the
potential for interference will help reach the goal of high availability. There
are two fundamental phases to this antenna alignment process:
 Pre-alignment or coarse-tuning;
 Final alignment or fine-tuning
The pre-alignment phase involves settings on the antenna prior to
installation and/or turn-on of the radio equipment. The final alignment
includes all steps taken after the radio equipment have been installed and
turned on.
Antennas have three adjustments for alignment:
 Polarization
 Azimuth (left and right)
 Elevation (up and down)
Coarse-tuning the antenna at time of antenna installation will ensure that
adequate signal is available for the fine tuning phase of the installation.
