Important notes:
1. Coaxial cables with copper clad steel center conductor are
not recommended.
2. Do not use splitters.
3. Line amplifiers are required for Receive cable runs of more
than 150 ft.
4. If the Receive cable run length is less that 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 a line
amplifier in the Receive cable only, at a minimum of 25 ft.
and up to 30 ft. from the LNB.
5. A line amplifier can only be installed in the Receive cable,
not in the Transmit cable.
6. Line amplifier specification: Channel Master 5113 IFD or
equivalent.

Grounding and Cable Choice
Your choice of grounding scheme may affect your choice of cable. Note that meeting the
National Electrical Code grounding requirements is easier if you use RG-6 with quad shield.
However, you can also use standard RG-6 and ground according to the Code or the
instructions in the antenna installation manual.

Type of cable to be used
Receive Transmit
Up to 300 ft. RG6 with solid copper
center conductor
(CommScope 5729 or

300 ft. to 420 ft. RG6 with solid copper
center conductor

equivalent)
RG6 with solid copper
center conductor and quad
shield (CommScope 5781
or equivalent)
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!
