3.7.3 RF Connections
CAUTION! Any open RF port on GX or improper connection
between GX RF ports and combiner inputs, will damage GX
internal power amplifier after the equipment is powered on.
Make sure all connections are performed correctly before
powering.
Note: When deployed with GX quad-band (with EAWS) units, the GX
dual-band high-band RF services can be combined with the
quad-band low-band services using the dual-band combiner (P/N:
AK-GX-LH-COMB).
For direct connections to DAS antennas
1. Using the required coax cables, connect the GX RF port(s) to
the service antennas. One for SISO models and two for
MIMO models.
2. Ensure lightning protection for each antenna port.
3. Waterproof all RF ports (recommended drip loops).
4. Terminate any unused GX and RF ports.

For connections via GX external low/high-band combiner:
1. Referring to Figure 3.20 and using the provided DIN-to-DIN
cables, connect the GX RF service antenna port to one of
the two external combiners input ports (Port1/Port2).
Note: MIMO models require to external combiners.
2. Connect the combiners’ 7/16 DIN output connector to the
DAS antenna.
