What is Ka?
• What is Ka?
• The Ka band uplink uses frequencies between 27.5Ghz and
31Ghz and the downlink uses frequencies between 18.3 and
18.8Ghz and between 19.7 and 20.2Ghz.
• Ka band dishes are much smaller than C band dishes. Ka
band dishes vary from 2' to 5' in diameter.
• Ka band satellites typically transmit with much more power
than C band satellites.
• The higher frequencies of Ka band are significantly more
vulnerable to signal quality problems caused by rainfall,
known as rainfade.

What is A3 and MPEG4?
• What is A3
• A3 stands for Advanced Modulation, Advanced Coding and
Advanced Compression. It is a new technology that will
allow DIRECTV to offer more high-definition (and ultimately
standard) channels.
• What is MPEG4
• MPEG4 is the most recent version of a standard for the
digital representation of video, audio and certain types of 3D
information. It processes detailed 3D representation for
faces, human bodies and general 3D scenes. The 3D scene
representation points to the VRML (Virtual Reality Modeling
Language) standard as it's representation.

New mounts
• Why do we need a new precision mount?
• The new Ka orbital slots at 99° and 103° are centered
symmetrically around the existing DIRECTV 101° slot
• Another satellite company will be operating two future Ka
orbital slots that are very close spaced to our new 99° and
103° Ka slots.
• If the DIRECTV Ka/Ku antenna is not precisely aligned, the
other guys Ka orbital slots will interfere with DIRECTV Ka
programming
• The other Ka satellites are not on-line yet and incorrectly
installed DIRECTV Ka/Ku systems may not show up for
some time.

Things You Should Know
• The Ku and especially the Ka portion of the antenna
have a narrower beam width than previous DIRECTV
antennas.
• The Ka/Ku antenna requires over 10 times more
alignment accuracy than previous DIRECTV ODUs
• Complete Ka and Ku alignment is performed using
only the 101° and 119° Ku slots.
• A “Dithering” method is used to precisely align the
antenna by symmetrically detuning the antenna and
finding identical signal levels either side of peak.

Ka/Ku ODU Assembly
• Assemble the Antenna on the Ground
Why?
• It’s easier than on the roof.
• You won’t loose (as many) parts
• Less chance of damaging the ODU and LNB’s

Confidential & Proprietary
Ka/Ku ODU Assembly
Tips
• Assemble the 110°/119° LNB, bracket and
interconnect cables but don’t attach to LNB arm.
• The 110°/119° LNB has 3 sets of mounting holes for
different regions, see the region chart in the manual.
• Preset AZ, EL and Tilt according to customers Zip
code found in the guided setup of the H20 IRD.
• LNB’s and dishes are NOT interchangeable between
manufacturers at this time. The LNB and arm are
keyed to prevent mismatching

Ka/Ku ODU Mast Installation Procedures
• Attach the Mast to the house ensuring that all 3 center holes
will be secured into a 2”x4” stud, or roof truss, and use the 4
corner holes on every install.
• Monopoles are used to provide additional support for the
ODU
• Attach the ODU to the mast and house in one of the
following ways:

Confidential & Proprietary
Ka/Ku ODU Mast Installation Procedures
• Be sure to always seal the foot assembly and monopoles from
the weather using approved silicon caulk or bishop tape
anywhere water may leak into the house from the holes drilled.
• Pole mounts require at least 150LB of concrete
• Pole should be 2” in diameter and at least 16 ga.
• Pole should be 2’ below ground and 4’ above ground
• Pole should be modified so it will not spin (cut bottom of pole at
an angle or insert bolt through bottom)
• Using the supplied bubble level, level the mast and tighten all
necessary bolts.
• Failure to level the mast correctly will cause the peaking of the ODU
to be impossible.

Confidential & Proprietary
Ka/Ku ODU Installation Procedures
• Attach the pre-assembled ODU to the AZ/EL hardware.
• Slide the AZ/EL and ODU hardware onto the installed mast, and
tighten the mast clamp bolts just enough so the antenna has
only side-to-side movement for later Azimuth alignment.
• Run all necessary cables into the feed arm
• Assemble the LNB’s using the provided hardware
• Refer to the included LNB Zone chart for correct settings for
attaching the 110° and 119° LNB’s to the 99°, 101°, and 103° LNB’s
• Zone 1 will have the 110° and 119° LNB’s closest to the 99°, 101°,
and 103° LNB’s
• Zone 3 will have the 110° and 119° LNB’s furthest apart from the
99°, 101°, and 103° LNB’s
• Zone 2 will have the 110° and 119° LNB’s in the middle setting

Aiming and Fine-tuning the ODU
• Coarse align the Azimuth and Elevation
• Set the in-line signal meter for 101° RHCP (13 volts with no 22KHz
tone).
• Slowly rotate the antenna around the mast in the Azimuth direction
until a peak level is obtained, and then lock down the mast clamp
bolts.
• Using a ½” nut driver, adjust the fine elevation screw for maximum
signal level. If the fine elevation screw runs out of range, or is not
centered in its range of movement, loosen the elevation lock down
screw and move the coarse elevation slightly to keep the bolt
centered.

Confidential & Proprietary
Aiming and Fine-tuning the ODU
• Coarse Align the Azimuth and Elevation (cont.)
• Record the Coarse signal level at this point for comparison
during a later step.
• After coarse alignment, verify reception of 101° on the
customer’s IRD
• You may check channels 490 and 491 on any of the installed
IRD’s
