Hughes connectors, in conjunction with the dielectric grease on the
F-connector threads, provide weatherproofing for outdoor connections.
These connectors should be used in new installations, upgrades, and any
repairs.
Outdoor connectors on radios and ground blocks that are in areas with
corrosive environments (e.g. salt air) may need additional weatherproofing,
such as weatherproofing tape or a weather boot filled with dielectric grease.
For additional information on weatherproofing the connection, see
on page 48.
Ground connections
Properly ground the antenna assembly in accordance with all local and
national electrical codes.
The antenna assembly must be grounded. For grounding information, refer to your
training, best grounding practices, Hughes Field Service Bulletin (FSB)
HNS
Broadband Requirements for RG‐6 and RG‐11 IFL Cable Connectors, Ground Blocks
and Ground Block Location
(FSB 050518_01), and applicable parts of the National
Electrical Code (NEC).
Antenna mast
Ground the antenna mast at the Az/El mount. For specific grounding procedures,
refer to the documents listed above.
Radio
Although the radio contains a ground screw on its underside, use of this ground
screw is optional. The radio is grounded through the shield in the coaxial cable and
the ground block, and no additional grounding is necessary. For additional
grounding procedures, see the documents referenced above.
Pointing
This completes the installation. You must now point the antenna. See
the
JUPITER
Antenna Pointing Guide
(1039429‐0001) for details. For mech
anical adjustments
specific to this antenna, see Chapter 5
