SG 2000 Installation and Operation Manual
Tilt Selection
To use the tilt selection charts, first determine the system operating bandwidth, either 750 MHz or
870 MHz. Next, determine the desired system channel load either 77, 94, or 110 channels. Use the
corresponding bandwidth and channel loading chart to determine the preferred tilt, either low,
standard, or high.
Figure 2-11 illustrates the tilt selection chart for 750 MHz bandwidth and 77-channel load:
