3.4.3 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.
IMPORTANT! GX quad-band models GX-E17E85P19L70-40-AC and GX-E17E85P19L70-40-DC do not support coexistence
with other GX models. These must be connected to a separate RF path via a different RIU or different sector (for RIU-12).
Connecting these GX models to the same RF paths as other GXs may result in a VSWR alarm.
For direct connections to DAS antennas
1. Using the required coax cables, connect the GX RF ports to the service antennas.
2. Ensure lightening protection for each antenna port.
3. Waterproof all RF ports (recommended drip-loops).
4. Terminate any unused GX and RF ports.
