2.4 Antenna Feeder JumperPurpose

The antenna feeder jumper connects the main feeder to the antenna feeder interface onthe ZXSDR R8872A chassis, to transmit and receive signals with the antenna.

External View

The antenna feeder jumper is a 50 Ω RF cable with the diameter of 1/2” and a DIN-typeconnector. Figure 2-4 shows an antenna feeder jumper.

Figure 2-4 Antenna Feeder Jumper

Connection

One end of the antenna feeder jumper is connected to an antenna interface (ANT1 toANT4) on the ZXSDR R8872A, and the other end is connected to the interface that themain feeder corresponds to.

2.5 AISG/MON Interface CablePurpose

The AISG/MON interface cable is used to operate and maintain the RRU, control externalantennas, and monitor external devices. Dedicated cables are used for different purposes.

External View

Figure 2-5shows an AISG/MON interface cable at one end of the ZXSDR R8872A.

Figure 2-5 AISG/MON Interface Cable

Connection

One end of the AISG/MON interface cable is connected to the AISG/MON interface on theZXSDR R8872A, and the other end is connected to an external device (AISG interface,monitoring dry-contact input device, monitoring RS485 device) or a debugging computer.
