Stage 1: Preliminary Survey
A preliminary survey is necessary before visiting potential installation sites. As much detail as
possible should be obtained about the designated ODU installation sites and the area
between them.

To perform a preliminary survey:
1. Mark the designated installation sites on a topographic map of the area.
2. Measure the distance between the sites; check that it is within the specified range of
the equipment.
3. On the urban map, check for developed areas situated between the installation sites.
Pay attention to these areas when performing the physical site survey; there may be
tall buildings, RF towers, or transmitters, which could cause interference to a sector.
4. Check the area between the two sites for obstructions such as:
• High ground ‐ hills or mountains
• Lakes or large bodies of water. Water has a reflection effect on RF signals like a build‐
ing. This type of reflection causes the received amplitude to be reduced. As a rule of
thumb, the presence of a large body of water between sector sites may double the
required antenna height.
