Repeater Installation

2-9.1 METHOD 1 – MULTIPLE REPEATERS
This method is straightforward and actually increases the composite output power of the system by
maintaining the maximum output power per carrier. For example, a repeater with a 10Watt output
will provide a composite of 20 Watts if used in a 2 repeater configuration where each repeater
transmits 1 signal. See the Figure 1 below.
Figure 1 Multicarrier for Highest Output Power
This arrangement can be expanded to more carriers if necessary. Notice how a dual polarized antenna
is used for the server. This allows you to run each repeater output to the antenna without using a
power combiner. The 3dB loss of signal power associated with a power combiner is eliminated.
This method produces the highest composite output power at the expense of more equipment.
