Some Outdoor Stuff
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.
Grounding Block
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 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.
