Routing RG 6 Cable(s)
STEP
You'll route RG 6 cable from your receiver to the cable grounding
block, then from the grounding block to the triple-head LNB.
Before starting, inspect the inside of each cable connector for
foreign materials and/or short. Make sure that the copper center
conductor is straight and centered in the connector.
Run cable from receiver
Verify that there are no wires or pipes blocking the location
where you want to feed the coaxial cables into your home. Drill
a 1/2" inch hole for each cable. Connect cable to the "Sat In"
jack on the back of your receiver. To prevent short, leave
receiver unplugged until Step 9.
Connect to grounding block
Mount the grounding block close to the point of cable entry
into the house. Connect cable to grounding block as shown.

Grounding Cable and Antenna
STEP
Grounding the antenna and cable grounding block help protect
the satellite receiver system and other components from
lightning damage.
Ground wire can be attached anywhere on the metal part of
•
the antenna, but there is a convenient grounding screw at
one side of the mast base. Installation should comply with
local codes and the National Electric Code (NEC, Sections
250 and 810).
Grounding point can be outside metal cold water pipe at
•
point of entry (no gas or hot water pipes), 8-foot ground rod,
grounded metallic service raceway, grounded electric service
equip enclosure, etc. Option #1: Both ground wires go to
the same ground point. If the two grounding points are
different, a #6 copper wire should be connected between
them. Option #2: The dish antenna grounding wire goes to
grounding block first, then to the grounding point.
