Final Installation
Note
When using a pole mount, you need
to attach the grounding wire to the
metal pole using a 1 1/2” grounding
clamp.
Step 8: Connect Cables and Ground Wire to the
Grounding Block
a. Make a 3"–5" drip loop using cable clips at the grounding block as shown on
the bottom of this page. This will prevent water from running into the
connection at the grounding block. Connect the cables to the grounding block.
b. Connect the grounding (messenger) wire to the grounding block.
Step 9: Route and Ground to the Central Building Ground
a. Locate an acceptable central building ground, which include any of the
following:
• 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.
• Eight-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).
b. Locate the grounding wire (#10 copper or #8 aluminum) that will extend from
the grounding block to the central building ground.
c. Attach the grounding wire to the grounding block by placing it through the
wire hole in the grounding block and tightening the screw.
d. Route the grounding wire from the grounding block to the central building
ground, and connect it to the central building ground.
Step 10: Route Cables Into Your House
Step 8a: Route cable from
antenna.
Step 8a: Make a drip loop.
Connect the coaxial cable(s)
from the antenna and the
grounding wire from the
mounting foot to the
grounding block (up to 4
connections).
Steps 9b and 9d: Connect the #10 copper
or #8 aluminum
grounding wire and route
to the central building
ground.
Step 8a and 8b:
Cable Routing Tips
• If you are routing the grounding
wire along the ground, make sure
the wire is buried deep enough so
that it will not be damaged or
uncovered.
• If you are routing the wire or cable
above the ground, use cable clips
to secure the two to a wall or
surface.
• Make sure you route the
grounding wire in an area where
people or animals are not likely to
come in contact with the cable.
