Interfacing the Fusion Main Hub to an RF Source
Connecting a Fusion Main Hub RF Band to Multiple BTSs
WARNING: Only LGC personnel or LGC-authorized installation per-
sonnel should connect the Fusion Main Hub to a base station or
repeater. Exceeding the maximum input power could cause failure of
the Fusion Main Hub (refer to Section 5.2 on page 5-4 for maximum power spec-
ifications). If the maximum composite power is too high, attenuation is required.
You can use power combiner/splitters to connect a Fusion Main Hub RF Band to
multiple base stations, as shown in Figure 7-28.
