Overview Of Grounding The Satellite System - Hughes DW 3000 One-Way Installation Manual

OVERVIEW OF GROUNDING THE SATELLITE SYSTEM

The two basic methods for mounting the satellite dish (univer-
sal mount with or without brace kit and pole mount) require
different grounding procedures, as specified in National Elec-
trical Code (NEC) Articles 250, 800, 810, and 820.
Both methods use the RG6 quad-shielded coaxial cable shield,
ground block, and ground wire for the system and protective
ground. The RG6 quad-shielded coaxial cable 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 41. The cable shield must be
less than .6 ohms per 100 ft; if it is not, a 14 AWG copper or
8 AWG aluminum ground wire must be run from the satellite
dish base ground to the ground block. The connectors must be
waterproof 360-degree compression type connectors. The
specified RG6 cable and connector must be used to meet NEC
requirements. These items are available through your local
electronics supply store.
POLE MOUNT GROUNDING
The mast (which is the metal pole in this mount method) is
grounded to the satellite dish 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 con-
nects the satellite dish 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 41.
When the mast requires a separate ground rod the NEC
requires that a 6 AWG copper wire must connect the mast
ground rod to the building earth ground.
UNIVERSAL MOUNT GROUNDING
The mast is grounded to the satellite dish via an NEC-approved
ground wire. The RG6 coaxial cable connects the satellite dish
to the ground block. The RG6 shield is used for system and
protective ground. An NEC-approved 8 AWG aluminum
ground wire is used to connect the ground block to the earth
ground using one of the three schemes shown in Figure 41.
