Objectives

Confidential & Proprietary

• Train technicians on basic Ka technology

• Train technicians to successfully complete an

A3-KaKu ODU installation and upgrade

• Train technicians to assemble KaKu ODU

• Train technicians on mounting options of

KaKu ODU

Objectives (cont)

Confidential & Proprietary

• Train technicians on ODU peaking methods,

including Dithering (fine tuning)

• Train technicians on how to install H20 HDTV IRD

• Train technicians on the use of the BBC (B band

converter) for use with All H20 IRD's

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.

Confidential & Proprietary

• 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

Confidential & Proprietary

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

Confidential & Proprietary

• 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.

• Why is a new mount needed?

Ka/Ku ODU Assembly

Confidential & Proprietary

• 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

Ka/Ku ODU Assembly

Confidential & Proprietary

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

Confidential & Proprietary

• 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:

Ka/Ku ODU Mast Installation Procedures

Confidential & Proprietary

• 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.

Ka/Ku ODU Installation Procedures

Confidential & Proprietary

• 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
