LFR Cabling Procedure

Step
1 Using the wire cutters, cut off the 5–pin circular connector.
2 Connect the 9 pin D connector to the LFR antenna, route the twisted pair cable through the previously
installed conduit from the LFR antenna to the RF Cabinet I/O area, and to the punch block through the
rubber boot in the floor of the I/O area (See Figure 5-6). Refer to Figure 5-1 for the recommended
locations.
NOTE
The rubber boot is sized to seal a cable with an outer diameter of either 1/4" or 1/2", if a different
sized cable is used heat/cold shrink or other means may be required to ensure a good seal. A tie wrap
or hose clamp must be used to ensure a good seal around the cables at the boot.
3 Connect the LFR pairs from the cable to the punch block (using only the recommended 110 style
punch tool CGDS237744 or equivalent) per the pin call–outs in Table 5-15.
Strain relief the cable by tie wrapping it to the punch block mounting bracket as shown in Figure 5-5
