2.2 Antenna Orientation

Careful placement of the antenna is necessary to ensure clear reception. Position the

antenna so that it is:

• In clear view of a Radio Port

• Not blocked by buildings, summer foliage nor heavy

traffic of large vehicles

• At least 2 meters in height, use Coverage Map and

on-site measurements to determine exact height,

usually 2 meters or higher

• Directed towards the strongest RSS measurement,

for directional antenna only

• On a wall or pole that is sufficiently strong, make

sure wall or pole can withstand winds common to

the area

• Away from other objects such as poles, trees,

buildings, and so on that block the signal from the

Radio Port; in general the minimum distance is 750

mm.

Antenna Type Determination Guidelines

The Coverage Map shows Radio Port locations and the area covered by the RP. The

type of antenna installed depends on its distance from the Radio Port. In general:

If distance is… Then use…

Less than 500m 4.5 dBi omni or directional

antenna

Between 400m and 700m 7 dBi omni or directional

antenna

Greater than 700m 10 dBi directional antenna

Table 2-1: Antenna Type Determination Guidelines

There may be exceptions to the requirements in Table 2-1 identified by on-site RSS

measurements and/or by the specific radio environment.
