Note: The keyhole style allows for fine-tuning of the horizontal level.

Figure 14. Leveling the NU

10. With the NU attached to wall, drill holes for each remaining anchor.

11. Unscrew the top two screws slightly, so the unit can be removed, but leave the screws in the wall.

12. Remove the NU from the wall and hammer the bottom two drywall anchors into place.

13. Hang the NU back on the top two screws and re-tighten those screws.

14. Screw the bottom two screws into place, through each bottom tab hole.

The unit should now be firmly attached to the wall.

Connecting Donor Source

The QUATRA 4000 has four independent RF ports for connecting the donor signal. Each port:

 Is an N-type Female connector

 Is specific to the supported operator

 Supports one and only one operator

 Is designed to support a variety of band configurations

Donor Antenna

Each RF port can be fed by a donor signal consisting of either a small cell or an antenna. Nextivity offers a number

of donor signals perfect for use with Cel-Fi QUATRA 4000.

Note: Small cell inputs and off-air inputs can be used in the same system, but not for the same donor port.

The donor antenna is used to collect the donor signal from the external (over-the-air) carrier network. Better donor

signals lead to better customer experiences, improved voice quality and faster data throughput. An RSRP signal-to-

noise ratio (SiNR) of >0dBm is strongly recommended for each given carrier’s source signal. Better SiNR leads to

better throughput.
