6.4.3 Installing Dual Band RAU Configuration
CAUTION: Install RAUs and diplexers in indoor locations only. Do
not connect an antenna that is installed in an outdoor location.
Dual band RAU configuration consists of:
• 1 higher band RAU
•1 lower band RAU
• 1 Dual-Band Diplexer (PN #DIPX1-1)
• 2 coaxial cables, 3 ft. long (PN #4005-3)
Installing RAUs in a Dual Band System
A Dual-Band Diplexer is used to combine the output of a low-band RAU and a
high-band RAU to a single
dual band antenna.
Considerations:
• The Diplexer will have a high loss if it is connected incorrectly. When using it with
the Unison system, incorrect connections may trigger the Antenna Disconnect
alarm.
• When using the Dual-Band Diplexer, the Unison system Antenna Disconnect
alarm can detect if the cable is disconnected or cut between the RAU and the
Diplexer. This alarm, however, cannot detect if the cable is disconnected or cut
between the Diplexer and the antenna.
Figure 6-1 shows the RAU configuration in a dual band system. It consists of two
RAUs, one for upper band and one for lower band, a diplexer and two 3 ft. coaxial
cables.
