Step 6: Attach the Cable(s) to the LNB / Attach the LNB to
the Antenna
a. Hold the triple-head LNB close to the end of the LNB Arm.
b. Attach the cable(s) running through the LNB arm to the output jack(s) on the
triple-head LNB multi-switch.
c. Attach the triple-head LNB onto the LNB arm and fasten it with the included
mounting hardware (Philip screws and nuts).
d. Dress the cable(s) with the enclosed tie wraps, allowing for a water drip loop if
necessary.
e. Attach the grounding wire to the satellite dish’s mounting foot. The grounding
wire can be attached anywhere on the metal part of the antenna, but there is a
convenient grounding screw at the mast base.
Step 7: Attach Grounding Block(s) to Your House
Grounding the DIRECTV
®
System to the central building ground helps protect it and
other components from lightning damage. Dish installation should comply with local
codes and the National Electrical Code (NEC). Grounding the satellite system is
something you can probably do yourself. But if you’re not sure, you should contact a
qualified electrician.
a. Attach the grounding block(s) to the side of your house close to the point you
have chosen as the coaxial cable entry point.
b. You may have to use anchors, togglers, or wood screws depending on the
surface on which you are mounting the grounding block.
IMPORTANT
The United States National
Electrical Code (NEC) specifies
that coaxial cable that is
exposed to lightning shall be
connected to the grounding
system of the building as close
to the point of cable entry as
possible.
CAUTION
For the best protection to your
equipment, ground the dish
and the coaxial cables to the
same place in the building. If
you don’t do this, a nearby
lightning strike could damage
your dish, the receiver, and/or
your TV.
Step 7: Attach the grounding
block(s) to the side of your
house at your designated
entry point. You can use 2 2-
way blocks or one 4-way
block.

Note: You have up to
four LNB output jacks
available to connect
additional satellite
receivers, but if you
plan to connect less
than that, we suggest
you use 75 ohm
termination caps for
the jacks you’re not
using (found at most
satellite retailers), and
protect them from the
environment with
electrical tape.
