DANGER!!!
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 it 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 attempt to assemble, move
or mount a dish on windy days or serious, even fatal accidents may occur. The manufacturer is not responsible or
liable for damage or injury resulting from antenna installations.
WARNING!!!
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. The manufacturer will not
accept liability for any damage caused by a satellite system due to the many unknown variable applications.
WARNING!!!
Antenna installations requiring the installer to work elevated above the ground level should be performed only by trained
professional installers. Failure to comply may result in personal injury or death.

This Installation Manual provides all the information you require to install your system. The instructions are fairly simple,
providing step-by-step instruction for system installation. However, it will require skills in construction, wiring and
assembly to correctly complete the installation.
WARNING: All satellite dish systems must be properly grounded. National and local electrical codes may
require you to ground the dish directly and to insert a grounding block in the coaxial cables running from the
dish to the receiver inside the building. Before beginning installation, carefully read the section on grounding
the dish.

MOUNTING LOCATIONS
Key points to remember when installing your 75E Elliptical Antenna System:
•Do not drill any holes until you’ve confirmed the best location for the dish.
• Make sure the installation of the dish conforms to local electrical and building codes, zoning requirements and other
applicable laws and regulations. If you are unsure, contact your local electrician or building inspector for assistance.
•For possible periodic removal of snow, choose a site that is easily accessible.
•Ensure there are no visible obstructions between the dish and your line of sight to the satellites. Keep in mind that trees will
grow up and outward and may eventually block the signal.
•The maximum allowable length for the RG-6 coaxial cable connecting the receiver to your dish is 125 feet.
• Use only RG-6 grade coaxial cable. Using lower grade RG-59 coaxial cable may result in excessive signal loss and
poor reception. Cable grade type is indicated on the outer jacket.
• Do not install the dish:
• Under power lines
• Where it may be easily tampered with
• Where it is exposed to high winds
• During windy or stormy conditions
Your dish must be mounted on a solid base. To ensure your dish doesn’t move in windy conditions, choose a location where
it can be securely fastened. The mounting surface should be rigid and solid.
IMPORTANT:The Elliptical Dish has a minimum turn radius of +/_35 degrees. If you are mounting the dish on the
side of your house, check the assembled dish and mounting pole to see if you can rotate the dish in the desired
azimuth setting. If you can’t rotate the dish, choose an alternate location.
Key things to remember when choosing a mounting location:
•The mounting surface should be flat, even and in good condition.
•If you install the dish on the roof or side of your house, be sure to attach the bolts into a building stud, rafter or other
solid surface.
•When mounting on the roof of your house, use silicon sealant around the holes where the base of the universal mount
meets the mounting surface. This will prevent the roof from leaking.
• We do not recommend:
• Mounting the dish on a railing
• Installing the dish on aluminum or vinyl siding (these are unlikely to be structurally sound)
• Keep grounding requirements in mind.

DISH ASSEMBLY
Step 1: To avoid losing any hardware components,
select a clear area on the ground for dish
assembly.
Step 2: On the Universal Mount, insert the (2) 20 mm
Carriage Head Bolts (Mast Adjusting Bolts),
through the mast and the curved slot of the
mount (Figure A).
Step 3: Attach the dish to the Clamp Mount Assembly
using the (2) 91mm and (2) 56mm long
Carriage Head Bolts (Antenna Mounting Bolts-
Painted Head), (4) Skew Lock Clips, (4) Lock
washers and (4) Nuts (see Figure B). Before
tightening the (4) bolts, refer to Skew Setting
Chart on Page 8 & 9 for the correct skew setting
for your geographic location.
Note: For single feed systems, tighten and torque the 4
bolts now as further adjustment will not be required.
Step 4: Pre-route the RG6 Coaxial Cable through the
Feed Support Arm then attach the Feed
Support arm to the dish using the 60mm Screw
Bolt, 5/16 Flat Washer, Spacer and Nut, making
sure the Feed Support Arm and Spacer Sleeve
are positioned as shown in Figure C.
Important: Installation of the Spacer is mandatory to
maintain rigidity. Ensure you tighten the Feed Support
Arm securely.

Step 1: Determine the direction in which to point the dish. Refer
to the Satellite Alignment Chart on Page 8 & 9. Record
value below.
“Initial Setting” starting reference from the Locator Chart
Azimuth Elevation Skew
________ ________ Set during Az/El
Mount Attachment
to the Dish
Step 2: Use a compass to determine roughly where to point
your dish.
Step 3: Choose a dish installation location with a clear line of
sight to the satellite based on the settings you recorded
earlier. There should be no trees, buildings or other
obstructions between the dish and the satellite. Do you
have a clear line of sight to the satellite?
•If YES, go to Step 4 and continue with the installation.
•If NO, find another location.
NOTE: To ensure an accurate compass reading, stay away from
large metal objects. To double-check accuracy, take multiple read-
ings several feet apart.
Step 4: At the dish install site, hold a compass level and still in
the palm of your hand. When the needle stops rotating
(dark half of the needle always points north), slowly
rotate the body of the compass so that the "N" marking
is aligned with the dark half of the needle. Locate the
tick mark on the compass edge corresponding to the
SAT azimuth number you wrote down earlier. This is the
direction in which to point your dish to receive signals.
TIP: Use a stick or other distant object to mark the “initial setting”
compass azimuth direction for SAT. Figure D).
Step 5: Estimate the satellite elevation (angle) settings you
recorded earlier, using a protractor. Check any obstruc-
tions at that elevation. If there are obstructions, then
select an alternate location for the dish.
IMPORTANT: When evaluating the install location, make sure
there are no trees, branches or objects visually obstructing the
dish and the general direction of the satellite. Also, keep in
mind that trees grow up and outward and may eventually block
the signal.

Step 1: Ensure mast is plumb before drilling any holes. Hold
the Universal Mount in place on the mounting area.
Use a carpenter’s level to plumb the antenna mast’s
straight section. If the bubble levels (horizontal and
vertical) are not centered, rotate the mast (in the
curved slot) until it is plumb. Then lock it in place by
securely tightening the Mast Adjusting Bolts (see
Figure E).
IMPORTANT: Initially finding the correct satellite signal and
turning to the satellite will be more difficult if the mast is not
plumb. Ensure the mast is plumb.
Step 2: Drill holes in the structure on which you are mounting
the dish to match the holes in the base of the
Universal Mount.
Step 3: Secure the Universal Mount with appropriate surface
screws (not included). Check the mount for move-
ment. An improperly secured mount will reduce signal
reception and reliability at a later date.
Step 4: Slide the Dish/Clamp Mount Assembly onto the mast
by loosening the (2) Azimuth Clamp Bolts (see Figure
B) and the Elevation Pivot Bolt just enough to slide the
assembly until it makes contact with the Elevation
Pivot Bolt (see Figure F). Tighten the Elevation Pivot
Bolt just enough to hold it in place on the mast.
Step 5: POLARIZATION SETTING:Polarization of the feed is
not needed. It should be set to zero from the factory.
Step 6: ELEVATION SETTING: Loosen the (2) Elevation
Locking Bolts sufficiently about 1 to 2-turns from tight
on either side of the Clamp Mount Assembly. Then
using the Fine Tuning Elevation Adjustment Bolt care-
fully adjust the dish elevation to the setting you record-
ed earlier. Tighten the (2) Elevation Locking Bolts and
re-check the dish elevation setting to ensure the set-
ting has not changed. (See Figure F).
Step 7: INITIAL AZIMUTH SETTING. Using your compass,
point the Feed Support Arm in the direction correspond-
ing to the azimuth setting (see Figure G). Draw a vertical
mark overlapping the Clamp Mount Assembly and the
mast. This mark will provide you with the approximate
starting reference point when you’re ready to find and
tune to the satellite.

GROUNDING
Step 8: Connect one end of the RG6 coaxial cable to the LNB feedhorn assembly. To install Weather Cap, gently bend the cable
to carefully fit the Weather Cap onto the LNB. Insert cap only about 1/2 inch. Avoid sharp bends to the cable.
Step 9: Before beginning the Tuning to the Satellite process, now is a good opportunity to sufficiently loosen the (2) azimuth
clamp bolts, the elevation pivot bolt and the (2) Elevation Locking Bolts and allow the dish to naturally settle on the
dish pole. While moving the dish back and forth on the pole, slowly and evenly torque all Azimuth Clamp Bolts,
Elevation Pivot Bolt and Elevation Locking Bolts. Eventually tighten all bolts to allow the Azimuth and Elevation Clamp
assembly to be firmly secured on the pole. The dish should not be able to be rotated on the pole with both hands.This
step will be helpful in minimizing dish movement after tuning.
Step 10: FINE TUNING: Follow instructions in the Satellite Receiver Manual or use signal strength measuring device for final
adjustments to obtain maximum antenna performance. Rotate antenna and Az-El cap, pointing to the correct compass
reading that was recorded earlier. Slowlysweep the antenna in azimuth until a signal is found. If desired signal is not
found, increase or decrease the elevation setting (in 1/2˚ increments) and repeat the azimuth sweep. Alternate between
elevation and azimuth fine tuning to reach maximum signal strength until no further improvement is detected. Tighten
and torque all hardware, referring to the Torque Chart on Page 1.
