This PATRIOT ANTENNA equipment is warranted to be free from defects in material and workmanship under normal
use and service. PATRIOT ANTENNA shall repair or replace defective equipment, at no charge, or at its option, refund
the purchase price, if the equipment is returned to PATRIOT ANTENNA not more than twelve (12) months after
shipment. Removal or reinstallation of equipment and its transportation shall not be at cost of PATRIOT ANTENNA
except PATRIOT ANTENNA shall return repaired or replaced equipment freight prepaid.
This Warranty shall not apply to equipment which has been repaired or altered in any way so as to affect its stability
or durability, or which has been subject to misuse, negligence or accident. This Warranty does not cover equipment
which has been impaired by severe weather conditions such as excessive wind, ice, storms, lightning, or other natural
occurrences over which PATRIOT ANTENNA has no control, and this Warranty shall not apply to equipment which
has been operated or installed other than in accordance with the instructions furnished by PATRIOT ANTENNA.
Claimants under this Warranty shall present their claims along with the defective equipment to PATRIOT ANTENNA
immediately upon failure. Noncompliance with any part of this claim procedure may invalidate this warranty in whole or
in part.
THIS WARRANTY IS EXPRESSLY IN LIEU OF ALL OTHER AGREEMENTS AND WARRANTIES, ANY IMPLIED
WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE IS LIMITED IN DURATION

INSTALLATION OF THIS PRODUCT SHOULD BE PERFORMED ONLY BY A PROFESSIONAL IN-
STALLERANDISNOTRECOMMENDEDFORCONSUMERD.I.Y.(DO-IT-YOURSELF)INSTALLATIONS.
WATCH FOR WIRES! Installation of this product near power lines is dangerous. For your
own safety,follow these important safety rules.
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.
Assembling dish antennas on windy days can be dangerous. Because of the antenna sur-
face, 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 attempt to assemble, move or mount dish on windy
days or serious, even fatal accidents may occur. PATRIOT ANTENNA SYSTEMS is not re-
sponsible or liable for damage or injury resulting from antenna installations.
Antennas improperly installed or installed to an inadequate structure are very susceptible
to wind damage.This damage can be very serious or even life threatening.The owner and
installer assumes full responsibility that the installation is structurally sound to support all
loads (weight,wind & ice) and properly sealed against leaks.PATRIOT ANTENNA SYSTEMS
will not accept liability for any damage caused by a satellite system due to the many un-
known variable applications.

INTRODUCTION
UNPACKING AND INSPECTION
Shippingcartons shouldbeunpackedandcontentscheckedfordamagedormissingparts. Should
therebeany parts that aredamagedormissing,please contact technical supportforreplacement.
ThankyouforpurchasingyourPatriotCommercial 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 the 75e Elliptical 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
futurereference andreadthe warrantyinformation.The serialnumbercan befoundon theantenna
back structure.
SITE SELECTION
The main objective of conducting a site survey utilizing a compass and inclinometer is to choose
amountinglocationon the ground that will give you thegreatestamountofswingforazimuth and
elevation for present as well as future use. A thorough preinstallation site survey is strongly rec-
ommended 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, unob-
structed 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.
Itisimportanttoconductanon-sitesurveywithaportableantennaorwith a compass and clinom-
eter to avoid interference, obstructions, etc.
Whenselecting“look angle”,besuretoobserve and takereadingsapproximately10 deg totheleft
andright,aboveand 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.
Beforedigging isdone,informationregarding thepossibilityof undergroundtelephonelines,power
lines, storm drains, etc., in the excavation area should be obtained from the appropriate agency.
Aswithanyothertype of construction, a local building permit may be required before installingan
antenna.Itisthepropertyowner’sresponsibilitytoobtainanyandallpermits.Groundmountsare

Feed Adjustment (Polarity tuning)
1. Adjust the Feed to the appropriate skew angle
usingtheprovidedscalereference.
NOTE: Refer to the chart below for polarization
angle. Elevation and polarity are both dependent
on site azimuth and the difference between satel-
lite and site longitude.
NOTE: Some satellites have a slant angle with re-
spect to the satellite belt angle. Contact the satel-
liteoperator for details.

Antenna Pointing
NOTE: The Reflector contains a 19 degree offset look angle. Therefore, when the reflector
aperture is perpendicular to the ground, the antenna is actually looking 19 degrees in elevation.
Elevation of Satellite above horizon = Measured angel from face of reflector plus 19.
1. Determine the elevation angle of the desired satellite, and rotate the elevation bracket to this
angle,andtightenhardwareto hold in place.
2. Azimuth Adjustment: With the electronics set to acquire the satellite, rotate the antenna in
azimuthuntil the satelliteisfound.Roughly obtain thestrongestsignaland tighten thehardwareon
the Pipe Bracket.
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. Peakthesatellitesignalbyfine
adjustmentsmadeinboth azimuth
and elevation until the optimum
signal is achieved.
4. Tightenallmount hardware.

5. Patriot recommends the use of cross pol nulling using a spectrum 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 assembly roughly 90 degrees to obtain a cross pol
null.Fine tune the null. Thescaleon the feed horn canbeused with the tick mark onfeedholder
toportheseambetweenfeedholdertopandbottom.The tick mark and seam are 90 deg. a part.
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
degreesandtighten the feed clamp.
NOTE:For Rx only, Installation is complete.ForTx/Rx Installation, continue to step 5.
