3.4.4 Installation
3.4.4.1 Mounting the Antenna
Prior to mounting the Antenna Unit, mount the antenna following your system
installation plan in the assigned locations. Follow the antenna manufacturer guidelines
to do so.
CAUTION
The antenna must be installed / positioned at a distance of greater than 20 cm away
from the proximity of operators and intended operators.
3.4.4.2 Mounting the 277X Antenna Unit
The 277X AU package should contain the following items:
o 1 × 277X AU
o 2 × SMA (male) – SMA (male) jumper cables
o 1 × PoE converter (incl. mains cable and 1m Cat5 Ethernet cable) – optional
o 1 × 19” equipment rack mounting kit (shelf and screws) – optional
Connect the SMA (male) – SMA (male) jumper cables to the provided SMA (female)
ports on the 277X (Figure 3-23).
Figure 3-23: Connecting the RF jumper leads on the 277X AU.
NOTE
Once connected, do not remove the jumper leads as they are required for the
functioning of the 277X Antenna Unit.
The Antenna Unit can be mounted to a ceiling or a wall or any horizontal or vertical flat
surface. Alternatively the AU can be installed in a 19” equipment rack using the
optional mounting kit.
For ceiling or wall mounting, chose the Antenna Unit position following these
guidelines:
o Mount the Antenna Unit as close as possible to the relevant antenna such that
the minimum length of coaxial cable is required to connect the AU to the
antenna. Excessive coaxial cable lengths will reduce the available signal power
and increase the uplink noise figure.
o Allow space above and below the unit for adequate ventilation and to
accommodate the minimum bend radius for the coaxial and fiber cables
