Install the satellite modem
Note:
You must install the satellite modem before installing the antenna to
determine the proper antenna pointing values (azimuth, elevation, and tilt).
For installation instructions, refer to the appropriate installation guide for the
satellite modem you are installing.
Determining the pointing values and polarization setting
Pointing values
Once the satellite modem is fully powered up, connect your smart device through a
wireless router and, using OASIS, set the pointing parameters for the antenna by
following the instructions OASIS gives. If you need further guidance, consult the
OASIS User Guide
(1040630-0001).
Alternatively, connect it to your laptop either wirelessly or by using an Ethernet
cable, and then use your GPS receiver to calculate the exact latitude and longitude
of the antenna site. Follow the instructions in the
JUPITER Antenna Pointing Guide
(1039429‐0001) to enter the latitude and longitude information to determine the
initial antenna azimuth, elevation, and tilt values. Record these values and keep
them handy for reference as you install and point the antenna.
Polarization setting
At the satellite modem System Control Center, enter the installation parameters as
presented in OASIS, or, if you are using a laptop, as presented in the satellite
modem software, to obtain the required polarization setting (either left-hand
circular polarization [LHCP] or right-hand circular polarization [RHCP]). Make a note
of the required setting for reference when you install the radio. See the
JUPITER
Antenna Pointing Guide
(1039429-0001) and the
OASIS User Guide
(1040630-0001)
for more information.
Install the antenna mount
Before installing the antenna, you must first install a suitable antenna mount. If the
system requires a pole mount installation, be sure to obtain information about any
underground utilities in the proposed location. Have the appropriate utility
company mark the location of any underground telephone wires, storm drains, and
so on. Also, because soils vary widely in composition and load capacity, it may be
necessary to consult a professional engineer to determine the appropriate
foundation design.
If you are using QUIKRETE fast-setting concrete mixture to set the pole mount, it
will take about 4 hours for the concrete to cure to the point where you can safely
install the antenna. See the appropriate antenna site preparation and mount
installation guide for more information about using QUIKRETE.
Mounts installed with a standard concrete mix need at least 24 hours to cure before
you can install an antenna on the mount. Be sure to plan and schedule the
installation accordingly.
