Interfacing the Fusion Main Hub to an RF Source
Connecting a Fusion Main Hub to a Roof-top Antenna
TE 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 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, Band 2, or Band 3.
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, Band 2, or Band 3.
