OVERVIEW OF GROUNDING THE SATELLITE SYSTEM
The two basic methods for mounting the satellite antenna dish
(universal mount with or without brace kit and pole mount)
require different grounding procedures, as specified in
National Electrical Code (NEC) Articles 250, 800, 810, and
820.
Both methods use the RG6 coaxial cable shield, ground block,
and ground wire for the system and protective ground. The
RG6 coaxial cable with shielding is connected to the ground
block and serves as the system and protective ground. The
ground block is located at the point the coaxial cable enters the
building. The ground wire is connected to the ground block and
routed to the earth ground using one of the three ground
schemes in Figure 38. The cable shield must be less than .6
ohms per 100 ft. The connectors must be waterproof 360-
degree compression type connectors. The specified RG6 cable
and connector must be used to meet NEC requirements.
POLE MOUNT GROUNDING
The mast (which is the metal pole in this mount method) is
grounded to the antenna via an NEC-approved ground wire and
clamp. The mast clamp must have a good electrical connection
to the mast pole. The RG6 coaxial cable shield connects the
antenna assembly to the ground block. An NEC-approved
ground wire is used to connect the ground block to earth
ground using one of the three schemes shown in Figure 38.
When the mast requires a separate ground rod the NEC
requires that a 6AWG copper wire must connect the mast
ground rod to the building earth ground.
UNIVERSAL MOUNT GROUNDING
The mast is grounded to the antenna assembly via an NEC-
approved ground wire. The RG6 coaxial cable connects the
antenna assembly to the ground block. The RG6 shield is used
for system and protective ground. An NEC-approved 16 AWG
aluminum ground wire is used to connect the ground block to
the earth ground using one of the three schemes shown in
Figure 38.
