3.4.3 Connect RF Cable(s)
WARNING:
Ensure the RF antenna feed is connected properly before activating the cell
and transmitting RF signals. The wireless signal transmission power can cause bodily
injury, and damage to the eNB and RF power amplifier devices.
NOTE: The Nova846 has eight antennas (ANT0–ANT7), but only ANT0–ANT3 are currently
used.

2.
Insert the RF cable(s) into cold shrink tubes.
3.
Connect RF cable(s) to the
ANT0
,
ANT1
,
ANT2
, and
ANT3
interfaces on the eNB, and tighten
them with a wrench to 12–15 in-lbs or 1.4–1.7 NM torque.
NOTE: Only antenna ports ANT0, ANT1, ANT2, and ANT3 are used for single carrier
mode. For CA and DC mode, antenna ports ANT0, ANT1, ANT2, and ANT3 connect to the
