A properly grounded multi-dish switch can take the place of a
ground block. The following instructions apply to a block or a
switch.
You may want to install the ground block onto the side of the building,
or on some other sturdy structure near the satellite dish. Make sure
that the location is stable, and that you fasten the ground block tightly
to the surface. As stated in Article 820-40 of the National Electrical
Code (NEC), locate the ground block as close as possible to the power
entry ground.

1. Mount the ground block so that its connections are horizontal. This
helps keep moisture from leaking into the block. Using the shortest
path possible, run the coaxial cable(s) from the LNBF(s) to the
input(s) on the ground block.
2. Put a drip loop in each cable to allow moisture to drip from the cable
before it runs into the ground block.
3. Run the ground wire to the power entry ground of the building in
accordance with the National Electrical Code (NEC) and all local
electrical codes.
