3-6 iRM4451nn00-2 iRRH Product Description and Installation Guide
through ANT1. The RF cables are supplied and pre-installed by the Installer in
lengths according to site requirements.
The 4.3-10 RF jack screw connector is secured by torquing the coupling nut to
44.25 in-lb (5 Nm) using a torque wrench.
NOTE
The Installer is also responsible for determining the antenna type, and supplying
and pre-installing the antennas at the site.
The recommended RF jumper cable is an IP-68 compliant, Amphenol 4.3-10, male
to 7/16 DIN male, with super flex cable (Part No. AAS-12HF-43SMDM-xM). The
variable x is the length of the jumper in meters, where x = 1.0, 2.5, or 5.0. The RF
jumper cable minimum bend radius is 1.2 in (30 mm).
NOTE
It is recommended that all RF cables be PIM-tested on site to ensure acceptable
performance.
3.2.3 Power connector
–48 V DC power to the iRM4451nn00-2 iRRH is through a 2-pin, EMI shielded,
circular twist-lock quick connect bulkhead jack, Rosenberger (99K73E-199N1).
The connector is keyed to prevent mis-mating. The power connector pin
assignments, as viewed from the bottom of the iRM4451nn00-2, are shown in
Figure 3-6.
