Now that you’ve decided on the exact mounting site, you need to
decide where you want the cable to enter the house, and then figure
out approximately how much cable you are going to need.

The diagram below shows you a “typical” installation scheme,
outlining the cables that are needed. The information on the following
page takes you through the cable estimating process step-by-step.

A Few Words About
Grounding the
System

Grounding the satellite
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.
