HUGHES-BRAND DIRECTV SYSTEM OWNER’S MANUAL
P AGE 4-14
Installation Procedure
1) Use a sledgehammer to drive the ground rod 8 feet into the ground near where you installed
the antenna base plate.
2) Insert the ¼-20 x ½-inch bolt through the grounding hole on the
base plate.
3) Install the star washer and ¼-inch nut onto the bolt.
4) Wrap the #8 aluminum grounding wire around the bolt between
the star washer and the base plate in accordance with National
Electric Code section 810-15, then tighten the nut.
5) Route the ground wire from the base plate to the ground rod.
Use the ground rod clamp to attach the ground wire to the
ground rod.
6) If necessary, secure the ground wire to the wall using insulated
U-shaped tacks.
Installing and Routing the LNB
Coaxial Cable
This section describes routing and installing the coaxial cable between the LNB and the grounding
block. Depending on the routing of the coaxial cable, you may
choose to use a cable that can be buried. When normal coaxial cable
is buried, its outer cover decays in the soil, and the cable’s life is
shortened. Cables that are suitable for burial use a special outer
cover that resists breakdown. Some of these cables also have a
special coating on their ground shields. This coating resists corrosion
if water gets into the cable. Anytime the coaxial cable is buried, use
cable that is suitable for burial. Doing so will help prevent problems
in the future.
An important goal of your cable installation is to protect the cable
from physical damage and moisture penetration. To protect the cable
from physical damage, secure it to walls or another stable surface
with cable clips. This prevents the cable from sagging and being
damaged by people stepping on it or running over it with yard
equipment. Prevent moisture penetration by using weatherproof connectors, or by sealing any
connection that is exposed to the elements. Drip loops provide a connection with additional
protection by preventing moisture from traveling down the cable and entering the connection.
Have the following tools and materials available:
•
Phillips screwdriver

Installation Procedure
1) Select the location where you will install the ground block. Choose a site that will be near the
cable entry point into the building. Also, plan a short and straight path for the ground wire to
the grounding rod.
