Hub installation

1. Support the cable above the roof surface with a cable trough
or wood blocks approximately 4 inches by 4 inches by 4

centimeters):

2. Tie down cable runs on the roof and at the IDU location
with tie–wraps.
3. Seal the IFL rooftop entry point with weatherproofing
caulk.
4. Label both ends of the IFL cable to identify the cable in an
appropriate manner. This is especially important if you are
installing multiple IFL cables. (To order IFL labels, request
HNS part number 9005328–0055.)
If you are installing multiple IFL cables for multiple HTs, follow
the instructions in this chapter for each IFL. However, you only
need to install one lightning arrestor for up to eight IFL cables,
because the arrestor design accommodates up to eight cables.
