3.2 Range of Operation
A single MicroWave 330 may cover a distance of 800 feet (244m). The receiver is equipped with automatic gain
control (AGC), which automatically adjusts receiver for the distance to be covered and sets the Path Fault
parameter.
Typical maximum width protection pattern of MicroWave 330 is shown in Figure 3 for mounting height of 2.5
feet (.76m) above smooth earth.
Maximum width will be when Transmitter-Receiver distance is at
maximum and Receiver “Sensitivity” control is set to maximum

Figure 4 illustrates how pattern width varies with Transmitter-Receiver distance and sensitivity setting. Actual
patterns will vary somewhat with site topography and surface condition. Generally, lower mounting height or
rougher surface will increase pattern width. For example, if the total link distance is 500 feet (152.4m) and the
sensitivity adjustment set to mid-point, Figure 4 indicates the detection pattern width to be 7.5 feet (2.3m).
