If the indoor equipment is installed on a raised computer floor, then cableways
are not required for that portion of the IFL cables under the computer floor.
The signal cables must be separated from any power cables at a minimum of
12 inches (30.5 cm). As a RFI and EMI preventive measure, the computer floor
shall be connected to station ground.
The opening through the computer floor into the equipment rack shall be large
enough for all electrical, signal, and data cables to pass as well as provide
ample ventilation for the equipment rack.

shall be connected to station ground.
•
The signal cables and power cables shall be installed in separate
conduits.
