4) Begin running the supplied cable through the roof girders as efficiently as possible
while utilizing Best Practices.
Coaxial cables are easily broken. If you pinch the line or bend it tightly, the inner-
core will break (the shielding will appear stressed). To ensure this does not
happen, it is best to uncoil the cable prior to beginning the cable pull.
5) Cables should be secured at each end with a required service loop at the point of
termination:
At the MEU, a minimal amount of cable will be left to facilitate a service loop to be
used during maintenance, if applicable. The remaining excess cable length will
have a service loop at the antenna and must be coiled and secured to itself using a
minimum of two cable ties per loop.
o The service loop must be free-floating at a minimum of 12 inches above the
termination point.
o The service loop should be formed in order to facilitate future maintenance.
o Under no circumstances should a service loop be attached to a support wire for
the ceiling grid.
6) Cables pulled from the store into the stock room must adhere to the following
standards:
Use an existing opening from the store to stock room if possible. Many times there
is an opening by the bottom of a roof girder.
Do not use any existing opening that has power conduits, water pipes or AC ducts
running through it.
If you need to cut a new hole through the wall for the cables, use the appropriate
tool such as a drywall saw or hole saw to cut the hole. Make the hole as small as
possible, but big enough for the needed cables.
Under no circumstances are you to punch or kick a hole in the wall to run cables
through. This will damage the wall.
If a firewall is present, then a firewall conduit sleeve is required to pull the cables
into the stock room. You must also use Fire Stop (caulk) to seal around the
sleeve. Follow the procedure specified by the manufacturer to install the firewall
conduit sleeve and use all the recommended fittings.
