CABLE SPECIFICATIONS
Note: Coaxial cables with copper clad steel center conductor are not recommended.
Note: Do not use splitters.
Note: Line amplifiers are required for Receive cable runs of more than 150 ft.
Note: The grounding scheme you choose may affect your choice of cable; see “Overview of Grounding the Satellite System” on
page 29.
Use plenum grade cable only if the cable is to be run in plenum space which is carrying return air for the air circulation system, or
when local laws require it.
If the Receive cable run length is less than 150 ft., then no line amplifier is required. If the Receive cable run length is greater than
150 ft., but less than 300 ft., then install a line amplifier in the Receive cable only, at a minimum of 25 ft. and up to 30 ft. from the
LNB.
A line amplifier, if needed, can be installed only in the Receive cable, not in the Transmit cable.
Line amplifier specification: Channel Master 5113 IFD or equivalent.
Grounding and Cable Choice
Your choice of grounding scheme may affect your choice of cable;
see “Overview of
Grounding the Satellite System” on page 29
for information about grounding. Note that
meeting the National Electrical Code grounding requirements is easier if you use RG-6 with
solid copper center conductor and quad shield. However, you can also meet the
requirements by using RG-6 with solid copper center conductor only and grounding the
mast as described in the Overview.

Important: A higher grade of cable can be used for an installation where a lower grade is
specified. For example, an RG6 cable with solid copper center conductor and quad shield
can be used for installations where the cable length is less than 300 ft. Never use a lower
grade of cable than specified. Be sure to record the grade of the cable used for your
installation. The grade is printed on the cable every few feet. Never use a cable which
does not have the manufacturers name and its grade clearly printed on it!
