DRAFT
Objective
The objective of this procedure is to install the cabling for the
antenna(s). This cabling is installed between the unit and the
customer–supplied lightning arrestor(s). If lightning arrestor(s) are not
required, the cabling connects directly to the antenna(s).
Cable Descriptions
The following cables in Table 4-30 are necessary to do this procedure.

LDF4–50
Customer
Supplied
RF Cable, 800 MHz, length selections: 10 m (31 ft.)
* Four antenna cables are required if one cCLPA is used. Six are required if two cCLPAs are used.
Procedure
Install the cabling between the BTS, external lightning arrestors, and the
cCLPA. If lightning arrestors are not present, the cables connect to the
antenna.
Cable the BTS as shown in Figure 4-37. Torque the connectors to 4.3
N–M (38 in–lbs).
Perform the procedure in Table 4-31 to install the antenna cables.
Table 4-31: Procedure to Install Antenna Cables
Step Action
1 Check with site documentation to determine proper location for mounting antennas.
2 If used, connect lightning arrestors. Surge arrestors are physically mounted to the rear flange of the
PDE.
3 With cCLPA configuration, proceed to step 4.
Without cCLPA configuration, proceed to step 6.
4 Route antenna cables to cCLPA and Compact BTS. See Figure 4-37 or Figure 4-38. Proceed to step 7.
5 Route antenna cables between cCLPA and Compact BTS. See Figure 4-37 or Figure 4-38. Proceed to
step 7.
5a If a TME is used (outdoor configuration), route antenna cables to appropriate TME connectors.
6 Route antenna cables to Compact BTS. See Figure 4-39. Proceed to step 7.
7 Dress cables as necessary, unless conduit is used.
