Objectives

• 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)

• 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.

• 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.


New Mount

Azimuth Fine-Tune

Elevation Fine-Tune


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.


Review Questions

• What is Ka?

• What is MPEG4?

• Why is a new mount needed?


Ka/Ku ODU Assembly

• Assemble the Antenna on the GroundWhy?• 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

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:


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.


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.



• 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


Review Questions

• Why is it necessary to course align the ODU?

• What polarity must you peak 101 to?



• Fine-tuning the Tilt• Set the in-line signal meter for 119° RHCP reception (13 volts

with 22KHz tone)• Slowly rotate the dish (left/counter clockwise,

right/clockwise), around the tilt axis, in order to peak the 119°signal, then carefully tighten the Tilt lockdown nuts


Aiming and Fine-tuning the ODU (cont)

• Fine-tuning the Elevation• Set the in-line signal meter for 101° RHCP reception (13 volts with no 22KHz

tone).• Looking at the back of the ODU, lock down the Left side Elevation bolt, leaving

the Right side slightly loose.• With the Elevation having been coarse peaked previously, now grasp the plastic

Elevation readout dial and rotate until 0 (zero) is lined up with the indicator.– Be careful not to turn the Elevation fine adjustment bolt during this step

• Using a ½” Nut Driver, rotate the Elevation fine tune screw exactly 2 turns Counter Clockwise and record the level from the signal meter. (This level will be lower than the that obtained in the Elevation coarse peak.)

– Note this signal level


Aiming and Fine-tuning the ODU Elevation (cont)

• Fine-tuning the Elevation (Cont.)• While counting the exact number of turns as well as fractions of a

turn, rotate the Elevation fine tune screw Clockwise (through the Peak) and continue until an identical signal level is reached as that recorded from the last step (roughly 4-7 turns). The numbers displayed on the dial will not correspond directly to the total distance turned.

– EXAMPLE: If you stop on 6 you actually moved 4 increments clockwise past zero, not 6.

– Record the number of turns• Divide the number of turns just recorded by 2. Reset the dial to

Zero, then rotate the Elevation fine-tune screw Counter Clockwise by the calculated amount.

• Signal strength should be equal to or greater than the original course peak number.

• Tighten the Elevation lock down nut.



• Fine-tuning the Azimuth• The Azimuth fine-tuning procedure uses identical

signal readings either side of peak in order to arrive at precise alignment.

• DO NOT DEVIATE FROM THE FOLLOWING STEPS!!!



• Fine-tuning the Azimuth (cont)• Verify that the Azimuth lock down bolts are slightly

loosened so as to allow free movement of the dither mechanism

• Set the in-line signal meter for 101° RHCP reception (13 volts with no 22KHz tone).

• Unscrew and pull out the Dither lock pin and verify dish will move slightly side to side without binding.

• Make sure to start with the azimuth dither pin centered.



Make sure these bolts areloose during alignment

Elevation Fine-Tune

Dither lock screw

Azimuth Fine-Tune



• Fine-tuning the Azimuth (cont)• Move the dish fully to the Left against the dither stop and

read the signal level. This level will be lower than that obtained during coarse Azimuth peak.

• Move the dish fully to the Right against the opposite dither stop and compare the signal level to the previous reading.



• Fine-tuning the Azimuth (Cont.)• Turn the Azimuth fine adjustment screw to increase the lower

of the two signal levels and repeat left/right dither process until IDENTICAL Signal Levels are achieved for the Left and Right stops. You may have to make several adjustments to achieve identical signal levels.

• When signal levels are Exactly the same at the left and right dither stops, then move the dish to the center of the dither range and replace the dither lock pin. You may need to move the dish slightly side to side until the lock pin is fully engaged.



• Fine-tuning the Azimuth (Cont.)• Tighten the Azimuth lock down bolts.• the current signal level should now be equal to or

greater than what was recorded for coarse alignment. A lower level would indicate a possible alignment problem and will require repeating the Fine-tune steps.

• Verify adequate signal levels are available for 101°, 103°, 110°, and 119° using the signal meter in the H20 IRD.– If they are low, repeat the Fine-tuning steps



• Fine-tuning the Azimuth (Cont)• You can damage the mount if threads bottom out and you

keep turning the fine-tune screws.• Strive for IDENTICAL levels between the left and right dither

stops.• Give the meter enough time to stabilize the readings at each

dither stop.• Move to the left and right dither stop by grasping the rear of

the mount, do not use the reflector/ODU.


Basic Dither Peak Principle

Hey, hey over here!Your Dither readings are not symmetrical!

Now your right on!
