Interfacing a Main Hub to a Base Station or a Roof-top Antenna
Connecting a Main Hub to Multiple Base Stations
You can use power combiner/splitters to connect a Main Hub to multiple base sta-
tions, as shown in Figure 7-9.

Connecting a Main Hub to a Roof-top Antenna
LGC Wireless recommends that you use a lightning arrestor or surge protector in a
roof-top antenna configuration. Insert the lightning arrestor or surge protector
between the roof-top antenna and the repeater that is connected to the Main Hub.
1. Connect an N-male to N-male coaxial cable to the roof-top antenna.
2. Connect the other end of the N-male to N-male coaxial cable to the grounded
surge suppressor.
3. Connect an N-male to N-male coaxial cable to the grounded surge suppressor.
4. Connect the other end of the N-male to N-male coaxial cable to the repeater.
5. Connect an N-male to N-male coaxial cable to the repeater.
6. Connect the other end of the N-male to N-male coaxial cable to the circulator
1 connector.
7. Connect an N-male to N-male coaxial cable to the circulator 2 connector.
8. Connect the other end of the N-male to N-male coaxial cable to the DOWNLINK
connector on the Main Hub.
