Connecting Multiple Main Hubs to a Duplex Repeater
or Base Station
Considerations:
• 2 hybrid power combiner/splitters; one for uplink and one for downlink (2x1 for
two Main Hubs, 3x1 for three, 4x1 for four, and so on.)
• 2 N-male to N-male coaxial jumper cables to connect each Main Hub to the power
combiner/splitters
• 1 circulator
• 1 N-male to N-male coaxial jumper cable between each circulator and the repeater
or base station
• 1 N-male to N-male coaxial jumper cable1 between each circulator and power
combiner/splitter
Procedure:
1.
Connect the Circulator to the power combiner/splitters and to the repeater or base
station using one N-male to N-male coaxial jumper cable.
2.
Connect each power combiner/splitter to the circulator using one N-male to
N-male coaxial jumper cable.
3.
Connect the power combiner/splitter to the Main Hubs:
a.
From the first Main Hub’s
UPLINK
port to the first power combiner/splitter
b.
From the first Main Hub’s
DOWNLINK
port to the second power com-
biner/splitter
c.
From the second Main Hub’s
UPLINK
port to the first power combiner/splitter
d.
From the second Main Hub’s
DOWNLINK
port to the second power com-
biner/splitter
4.
Check Main Hub LEDs.
After connecting and powering on the Main Hub, check all LEDs to ensure that
the system is operating properly.
NOTE:
Use a 50 ohm terminator on any unused power combiner/splitter ports.
