Interfacing the Fusion Wideband Main Hub to an RF Source

7-50 InterReach Fusion Wideband Installation, Operation, and Reference Manual

CONFIDENTIAL D-620616-0-20 Rev D

Connecting a Fusion Wideband Main Hub to a Roof-top Antenna

ADC 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.
