5.4 Installing RF antenna cables
The RF antenna cables are shipped installed on the iRU4438 iRRH. If for any reason
the RF cables are removed, the following procedure provides instructions for routing
and connecting the cables. The RF antenna cables connect to the omni-directional
antennas. The upper RF antenna cables are 10.5 in (26.7 cm) in length. The lower RF
antenna cables are 26.5 in (67.3 cm) in length.
DANGER
RF antenna coaxial cables may be damaged if bent or curved to a radius
that is less than the recommended minimum bend radius of 0.6 in (1.52
cm). Always observe the recommended bend radius limit when routing
coaxial cables.
The RF coaxial cables are routed from the N-type connector at the base of each omni-
directional antenna to the corresponding QMA RF jack located on the front of the
iRRH. Antenna and connector designations are shown in
Figure 3-5 and Figure 3-6,
respectively.
The four QMA RF jacks on the front of the iRU4438 iRRH are labeled ANT 1–4 (as
viewed from right to left) and as shown in
Figure 3-5. The four omni-directional
antennas are designated OMNI 1–4 and are configured as shown in Figure 3-6. The
RF cable routing is shown in Figure 5-4.
