Overview of the Outdoor Installation
Antenna Placement
To achieve maximum performance for your wireless outdoor connection, the RoamAbout Outdoor Antennas must have clear
•
•
No obstacles in the direct path between the two antennas.
No obstacles within a defined zone around the antenna beam.
The shape of a radio beam is not straight and narrow like a laser beam. The radio beam, also referred to as Fresnel Zone, is bulged in the middle, like a football or rugby ball. The exact shape and width of the Fresnel Zone is determined by the path length and frequency of the radio signal.
If any significant part of this zone is obstructed, a portion of the radio energy will be lost, resulting in reduced performance. Reduced performance may also occur when obstacles that are close to the antenna beam cause signal reflections or noise that interfere with the radio signal.
Figure 2-3 shows some typical examples of obstacles that you must avoid for a directional antenna to operate effectively:
A.Neighboring Buildings
B.Trees or other obstructions
C.Power lines
To allow optimal performance, ensure that the type and placement of the antennas allows sufficient clearance of the Fresnel Zone at the maximum width of the bulge, typically at the midpoint between the antennas. For more information, see Chapter 3 - Determining Range & Clearance.
