Connecting a Fusion Wideband 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 connected to the Fusion Wideband
Main Hub RF Band.
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 Hub for either Band 1 or Band 2.
Attenuation may be required to achieve the desired RF output at the RAU.
9. Connect an N-male to N-male coaxial cable to the circulator 3 connector.
10. Connect the other end of the N-male to N-male coaxial cable to the UPLINK con-
nector on the Hub for either Band 1 or Band 2.
