These cable specifications are the minimum required. If the cable
installation does not meet the minimum requirements, future applica-
tions may require that the entire cable installation be replaced with
the minimum required cable.

Grounding and cable choice
The choice of grounding scheme may affect the choice of cable. 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 or copper clad steel 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 RG-6 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 the
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!
