Estimating Cable Requirements
Here’s how to determine where to put the grounding block
and estimate the length of the RG-6 coaxial cables and
ground wires.
1. Locate the central building ground. You will ground the
dish and the cable grounding block to a single point in
the central building ground.
Acceptable central building ground points may include:
• grounded interior metal cold water pipe within five feet
of the point where it enters the building
• grounded metallic service raceway
• grounded electrical service equipment enclosure
• 8-foot grounding rod driven into the ground (only if
bonded to the central building ground by #6 or heavier
bonding wire)
• other acceptable grounding electrodes that comply with
sections 250 and 810 of the National Electrical Code (NEC)
2. Choose a location to mount the grounding block. The
block should be as close as possible to the point where
the cable will enter the house.
3. Estimate the distance between the grounding block and
the central building ground.
You need one (1) length of grounding wire ____________
feet long to run from the grounding block to the central
building ground.
4. Estimate the distance between the dish and the central
building ground.
You need one (1) length of grounding wire ____________
feet long to run from the mounting site to the central
building ground.
5. Estimate the distance between the intended mounting
site and the grounding block.
You need one (1) RG-6 coaxial cable ____________ feet
long to run from the dish to the grounding block.

Grounding Block
You must use RG-6 coaxial cable from
the DSS
®
dish to the Satellite In jack
on the DSS
®
receiver. Other types of
coaxial cable, such as those used for
cable television (RG-59) do not work
for the DSS
®
system.
If your total RG-6 coaxial cable length
is more than 112 feet, you may need
additional installation equipment to
compensate for the longer cable
length.
