IMPORTANT!!!
INSTALLATION OFTHIS PRODUCT SHOULD BE PERFORMED ONLY BY A PROFESSIONAL INSTALLER
AND IS NOT RECOMMENDED FOR CONSUMER D.I.Y. (DO-IT-YOURSELF) INSTALLATIONS.
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 instal-
lation.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. Channel Master®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. Channel Master will not accept liability for any damage caused by a
satellite system due to the many unknown variable applications.

Concrete - (See Ground Pole section for quantity and grade).
#3 Rebar - (See Ground Pole section for quantity). Deformed steel per ASTM A615, grade 40 or 60.
SITE SELECTION
The first and most important consideration when
choosing a prospective antenna site is whether or not the
area can provide an acceptable “look angle” at the
satellites. A site with a clear, unobstructed view is pre-
ferred. Also consider obstruction that may occur in the
future such as the growth of trees.Your antenna site must
be selected in advance so that you will be able to receive
the strongest signal available. To avoid microwave
interference, obstructions, etc. conduct an on-site survey
with a portable antenna.
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.
Before any 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.
Because soils vary widely in composition and load
capacity, consult a local professional engineer to
determine the appropriate foundation design and
installation procedure. A suggested foundation design
with conditions noted is included in this manual for
reference purposes only.

ASSEMBLY AND INSTALLATION
INSTALLING AZ/EL CAP MOUNT ONTO POLE
The AZ/EL Cap is factory preassembled, therefore, no
assembly is required.
Before installing AZ/EL Cap, concrete foundation should
be in place and cured.
Install AZ/EL Cap onto ground pole.If ground pole is 2⁷⁄₈”
O.D., install Item 3 vinyl cap as shown. Square Head
Locking Bolts should be tightened enough to penetrate
vinyl cap only. Item 3 is not used with 3”O.D. ground
pole.Tighten clamp nuts so that cap is held stationary on
the ground pole, but can be swiveled with slight pressure
(Ref. Fig. 1.0).
ASSEMBLING ANTENNA ONTO AZ/EL CAP MOUNT
Install four M8 x 91mm Plow Bolts into holes in reflector
face. Lift reflector and insert exposed portion of bolt into
holes in Antenna Mount flange.Install four LockWashers
and Hex Nuts on Bolts. Ref. 1.1.
Tighten and torque to 11 Ft. Lbs (15 N-m).
IMPORTANT: Note orientation of bolt holes in reflector
flange.Holes should be located on each side and bottom
of reflector as shown in Figure 1.1.
FEED AND FEED LEG INSTALLATION
Assemble Feed Legs to antenna (Ref. 1.2).
Insert M8 x 20mm Hex Bolt and Flat Washer thru hole in
bottom flange of reflector. Assemble Bottom Feed Leg
and secure with Lock Washer and Hex Nut.
NOTE: Bottom Feed Support Leg is the shorter one and
has two holes on one end.
Attach left and right Feed Legs to reflector using M6 x
16mm Hex Bolts, Flat Washers, Lock Washer and Hex
Nuts. (Note: Long formed end attaches to reflector.)
Assemble Feed Support Block (supplied with Feed
Package) to Feed Support Legs, using M6 x 16mm Hex
Bolts, Lock Washers, and Hex Nuts.
NOTE: Support Block is supplied with Feed Package.On
some models, it may be easier to assemble Feed Block
to Feed Legs, by removing Feed Horn Assembly from
Feed Support Block.
Refer to feed assembly instructions (included with feed
package) for assembly of ODU to feed.
Tighten and torque hardware securing Side and Bottom
Feed Legs to Feed Support Block and to Reflector to 4
Ft-lbs. (5.4 N-m).

Ground antenna mount assembly and feed cables in
accordance with current National Electrical Code and
local electrical codes. Figure 2.0 and 2.1 illustrates
typical grounding methods for the ground pole and
feed cables.
Clamps that provide a solid connection between ground
wire and ground source should be used.
Tighten and torque all hardware.
IMPORTANT: Sealing RF Coaxial Connector: The
copper-plated center conductor in the RF coaxial cable,
which connects receiver to LNB, can experience
electrolysis corrosion at the LNB connector. Moisture
and DC current causes this type of corrosion.To prevent
corrosion, apply a moderate coat of silicon grease to the
center conductor and wrap the entire connection with
COAX-SEAL®tape to seal.
GROUNDING

ANTENNA ALIGNMENT PROCEDURE
Alignment with the satellite is obtained by setting polar-
ization, elevation and azimuth. Charts 1, 2 & 3 are to
determine these values for your earth station antenna
site. “∆L”is the difference between the earth station
antenna site longitude and the satellite longitude. Use
“∆L”and your earth station latitude to obtain polarization,
elevation or azimuth setting.
POLARIZATION OF THE FEED
Loosen feed horn clamp bolts and turn feed clockwise or
counterclockwise, depending on being east or west of
the satellite as shown on Chart 1. Align marks on the
horn clamp and appropriate mark on the horn scale
Polarization chart assumes antenna system polarization
is Tx vertical and satellite vertical Pol is perpendicular to
plane of geostationary arc. For horizontal Tx of antenna,
feed must be rotated 90˚from values shown. (Starting
point for polarization adjustment is 0˚, as shown in Figure
3.0.)
Use a signal strength measuring device for final polar-
ization setting and tighten horn clamp bolts to 4 Ft-lbs.
ELEVATION
Use Chart 2 and determine your elevation setting.
Loosen bolts in curved slots (both sides) of AZ/EL hous-
ing approximately ¹⁄₂ turn (Ref. Fig. 3.1). Turn elevation
adjustment bolt clockwise to increase elevation.Align the
edge of the clamp with appropriate mark on housing at
the desired elevation reading.This will be an approximate
setting. Optimum setting achieved when fine tuning.
AZIMUTH
Use Chart 3 and determine your azimuth setting. Values
in chart must be adjusted for magnetic deviation for your
location for correct compass reading. Rotate reflector
and mount pointing it to the correct compass reading.
Slowly sweep the antenna in azimuth until signal is
found. If the desired signal is not found, increase or
decrease elevation setting and repeat the azimuth sweep
(Ref. Fig. 3.2). Tighten clamp bolts and clamp locking
bolts.
FINE TUNING
Use signal tuning device for final adjustments to obtain
maximum antenna performance. Alternate between ele-
vation and azimuth fine tuning to reach maximum signal
strength, until no improvement can be detected. Certain
models utilize the optional azimuth fine tune feature
(refer to Figure 3.2). This allows the azimuth to be fine
tuned by loosening the (4) carriage bolts and swivel nut
hex nut which allows adjusting the azimuth fine tune
adjusting bolt for the peak signal. Tighten and torque all
AZ/EL hardware to 12 Ft-lbs.
