Installing the iRU4438 iRRH 5 Installing the iRU4438 iRRH This section provides the procedure for installing the iRU4438 iRRH in remote locations such as on towers, poles, masts, walls, roofs, or other structures utilizing a universal mounting assembly. Instructions for making connections to external interfaces, cabling, grounding and power are also provided. 5.1 Assembling cables 5.1.
Installing the iRU4438 iRRH NOTE The grounding cable to the iRRH should be 3.9 in (10 cm) longer than other cables to the unit. This will maintain ground connection should the cables be pulled off when the unit is extended beyond the length of the cables. To install ground terminal lug: 1. Cut a 6 AWG (4.11 mm) stranded grounding cable the appropriate length for the iRU4438 iRRH installation. 2. trip away insulation from one end to expose 3/4 in (19 mm) of bare wire. 3.

Installing the iRU4438 iRRH 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.
Installing the iRU4438 iRRH Figure 5-7 RF antenna coaxial cable routing NOTE NOTE Leave the dust cover on any unused antenna port. The RF connections must be waterproofed using a self-fusing tape made for that purpose. The application of the tape will vary by Operator, so local practice will determine how the tape is applied. To install RF cables: 1. Route one RF cable from ANT 1 to OMNI 1.
Installing the iRU4438 iRRH 2. Connect the RF cable N-type connector to the OMNI 1 antenna and secure 15 in-lb (1.7 Nm). 3. Connect the RF cable QMA-type connector to the ANT 1 RF connector on the front of the iRRH by pushing on it until it snaps into place. 4. Repeat step 1 through step 3 for the remaining RF cables according to the RF cable connection scheme provided in Table 3-3. 5.
