.
1. Perform as many functions as possible on the ground.
2.Watch out for overhead power lines. Check the distance to the power lines before starting installation.
We recommend you stay a minimum of 6 meters (20 feet) from all power lines.
3. Do not use metal ladders.
4. Do not install antenna or mast assembly on a windy day.
5. If you start to drop antenna or mast assembly, get away from it and let if fall.
6. If any part of the antenna or mast assembly comes in contact with a power line, call your
local power company. DO NOT TRY TO REMOVE IT YOURSELF! They will remove it safely.
7. Make sure that the mast assembly is properly grounded.
WARNING
Assembling dish antennas on windy days can be dangerous. Because of the antenna surface, even slight
winds create strong forces. For example, a 1.0m antenna facing a wind of 32 km/h (20 mph) can undergo
forces of 269 N (60 lbs.). Be prepared to safely handle these forces at unexpected moments. Do not at-
tempt to assemble, move or mount dish on windy days or serious, even fatal accidents may occur. PA-
TRIOT ANTENNA SYSTEMS is not responsible or liable for damage or injury resulting from antenna
installations.

Introduction
Unpacking and Inspection
Shipping cartons should be unpacked and contents checked for damaged or missing parts. Should there be any parts that
are damaged or missing, please contact technical support for replacement.
Thank you for purchasing your Patriot Commercial Antenna. We trust that you will find this to be a well designed product
that will provide many years of reliable service. This manual covers the assembly and installation of the7.5m Antenna
System. Read this manual thoroughly before beginning assembly. For best results in the assembly process. Perform each
step in the same sequence as listed in this manual. Record the serial number of the unit on to page 2 for future reference
and read the warranty information. The serial number can be found on the antenna back structure.
Site Selection
The main objective of conducting a site survey utilizing a compass and inclinometer is to choose a mounting location on the
ground that will give you the greatest amount of swing for azimuth and elevation for present as well as future use. A thorough
pre-installation site survey is strongly recommended because it can alert you to any “look angle”, soil, wind or other
problems.
The first and most important consideration when choosing a prospective antenna site is whether or not the area can provide
an acceptable “look angle” to the satellite. A site with a clear, unobstructed view facing south, southeast is required. Your
antenna site must be selected in advance so that you will be able to receive the strongest signal available. Also consider
obstructions that may occur in the future such as the growth of trees.
It is important to conduct an on-site survey with a portable antenna or with a compass and clinometer to avoid interference,
obstructions, etc.
When selecting “look angle”, be sure to observe and take readings approximately 10 deg to the left and right, above and
below your selected “look angle”.
Before Ground Pole Installation, the soil type should be checked because soil conditions vary widely in composition and
load bearing capacity. A soil check will help you to determine the type
and size of foundation required to provide a stable base for the antenna.
Before digging is done, information regarding the possibility of underground telephone lines, power lines, storm drains, etc.,
in the excavation area should be obtained from the appropriate agency.
As with any other type of construction, a local building permit may be required before installing an antenna. It is the property
owner’s responsibility to obtain any and all permits. Ground mounts are certified for 125 mph wind survival.

Antenna Pointing
NOTE: The Reflector contains a 23 degree offset look angle. Therefore, when the face of the reflector looks perpendicular
to the ground, the antenna is actually looking 23 degrees in elevation.
The antenna look angle is actually the top side of the Feed Support Plates as shown below.
FOR FIXED MOUNT POINTING-
.
1. Adjust the reflector up or down in elevation by turning the two 2” hex nuts on the Elevation Rod Assembly until the
desired elevation is measured (taking Elevation angle measurement from the Feed Support Arms).
4. Patriot recommends the use of cross pol nulling using a spec-
trum analyzer during TX/RX installations. After tightening the
azimuth and elevation hardware, peak the co-pol signal using
the spectrum analyzer. Then rotate the feed assemble roughly
90 degrees to obtain a cross pol null. Fine tune the null. The
scale on the feed horn can be used with the tick mark on feed
holder top or the seam between feed holder top and bottom. The
tick mark and seam are 90 deg. apart.Note that changes may be
necessary to the resolution and video bandwidth to bring the
signal above the noise floor. Note the angle of optimum cross
pol null. Rotate the feed back exactly 90 degrees and tighten the
feed clamp.
2. Azimuth Adjustment: With the electronics set to acquire the satellite, use the double-nut threaded adjustment on the
Azimuth Rod.
NOTE: If signal is not found on first pass of Azimuth, adjust elevation up
or down in 2 deg increments until signal is found.
3. Peak the satellite signal by fine adjustments made in both azimuth
and elevation until the optimum signal is achieved.
Note: Adjust, tighten, recheck until optimum signal is reached in
both Azimuth and Elevation.

Antenna Pointing
1) Begin by obtaining the correct Az/El pointing data for the satellite of interest based for your site location.
2) Using an inclinometer or position readout form controller placed on the enclosure drum surface, position the
antenna to the specified elevation angle.
3) Manually scan the antenna (back-and-forth in the azimuth around the direction of the specified azimuth
angle) to achieve the maximum transponder signal.
4) Next repeat the procedure for elevation.
5) Repeat this procedure alternating between the azimuth and elevation until maximum transponder signal is
achieved.

Grounding Antenna Feed Cables
1. Ground antenna feed cables in accordance
with current National Electric code and local elec-
tric codes. The illustration shows a typical
grounding method.
Clamps that provide a solid connection between
ground wire and a ground source should be used.
Grounding Non-Penetrating

3. Insert plastic plug into end of feed support tube.
1. Adjust the Feed to the appropriate skew angle
using the provided scale reference.
NOTE: Refer to the chart on back for polarization
angle. Elevation and polarity are both dependent on
site azimuth and the difference between satellite and
site longitude.
NOTE: Some satellites have a slant angle with
respect to the satellite belt angle. Contact the satellite
operator for details.
