Tighten this connection securely. Ensure there
is a good electrical connection between your
mounting structure and grounding wire. Run the
grounding wire as straight as possible and use
stand-off insulators spaced four (4) to six (6) feet
apart. Attach the grounding wire to an acceptable
building ground location.
Examples of acceptable building grounding
locations are:
• The building or structure grounding electrode
system as covered in 250.50 in the NEC.
• Grounded interior metal water piping system,
within 5ft. from its point of entrance to the
building.
• Grounded nonflexible metallic power service
raceway.
• Service equipment enclosure, the grounding
electrode conductor or the grounding electrode
conductor metal enclosure of the power service.
• An 8ft. grounding rod driven into the ground can
be used as long as it is connected to the central
building ground by a #6 or heavier bonding wire.
Refer to the NEC sections 250 and 810 for other
acceptable grounding methods.
b) Antenna Connection: Connect one end of a
coax cable to the antenna and the other end to
a 75 ohm grounding block. Below (Fig. 6b) is an
example of a 75 ohm grounding block.
If you make your own coax cable, be sure to slide
the Rubber Boot over the cable before you place the
connectors on the cable. Once you have attached
the cable to the antenna, slide the Rubber Boot into
the round channel on the Main Housing Unit.
