Panasonic TADA2420 - ANTENNA SYSTEM User manual

INTRODUCTION
This antenna system, with the equipment supplied, can receive signals simultaneously from satellites located at 101°
and 119° West longitude orbital locations. This antenna system also has a reserved position for a satellite located at
110°W for additional services. If such services are offered in your local area, you will be notified.
The installation procedureslistedinthis manual require basic knowledgein construction,assembly and wiring. Inorder
to safely install this antenna system, you must be able to perform the following skills:
• Use hand tools for assembly.
• Drill and seal holes in mounting surfaces.
• Use a bubble level to plumb the mast. (Critical alignment - See Figure 2B.)
• Use a compass and inclinometer or protractor to determine clear line of sight to satellite.
• Install and run coaxial cables through the home from the antenna to the receivers.
• Climb ladders or roofs to mount and wire the antenna.
• Know local and NEC grounding codes. (The National Electric Code is published by the National Fire Protection
Association, 1BatterymarchPark,Quincy,Massachusetts, 02269-9959andmaybe availableatyourlocalpublic library.)
If you feel this installation is beyond your experience and skill level, then contact the store where the system was pur-
chased for advice on professional installation services in your area.
WARNINGS
Local building and electrical codes (see latest revision of National Electrical Code) require proper
grounding of the antenna mount and coaxial cables. Improper installations may seriously damage
the equipment or the building and cause injury or death to you. Contact a licensed inspector or
electrician in your area for assistance.
WATCH OUT for power lines which may be overhead, buried underground and/or hidden behind
walls. Take extreme careto avoid contact with any power lines with ladders, satellite system parts
or tools during the installation to avoid serious injury or death.

MOUNTING LOCATIONS
Typical mounting locations are shown below. The mounting surface must be solid and rigid to prevent the antenna from
moving during windy conditions.
When attaching to wood framed structures, use the center holes on the mounting base foot to fasten onto the center of
a stud or rafter.
When attaching to masonry structures, use the four outside corner holes in base foot and four appropriate ¹⁄₄"
double-expansion anchors or toggle bolts with flat washers (not included).
When using an optional accessory 1.66 O.D. steel ground mount pole (not included), dig a 12" diameter hole 36" deep
for the pipe. CAUTION: Make certain the area is free of underground utilities before digging. Place flattened end
of pipein concrete to prevent rotation andattach requiredgroundwire to punched hole.The pipe should extend atleast
30" into the concrete pier. (Refer to detailed installation instructions included in your optional pole mounting kit.)

in your local area, you will be notified.)
FINDING THE DISH POINTING COORDINATES
Finding the dish pointing coordinates for your location includes presetting the azimuth,elevation, andtilt. This is done
by following the directions from your satellite receiver that appear on your TV screen.
To accomplish this, make sure that your satellite receiver is properly installed to your television so that you can see the
menu directions on your TV screen. Your satellite receiver does not need to be connected to your antenna for this step.
See the User’s Manual that came with your satellite receiver for more information about finding the antenna’s pointing
coordinates for your site ZIP Code number.

HOW HIGH UP IN THE SKY IS THE SATELLITE?
Depending onwhere you live, the satellitewillbeat anelevation angle between 30 and 60 degrees. Southern states point
toward 60 degrees; northern states point more toward 30 degrees.
FINDING A CLEAR LINE OF SIGHT
1. Go outside and locate at least one site on your property that has a clear view to the satellites. You should be
reasonably certain you are pointing toward the satellites, depending on where you live. You may want to use a map
or a compass.
2. To determine the approximate height of the satellite in the sky, imaginea vertical arc ranging from 30 to60 degrees
above the horizon. (See next page.)
3. Do you have a clear view to the satellites? Remember, no trees, leaves, buildings, or windows can be between the
dish and the satellites.
If the answer is NO, look for other locations for installing the antenna system.
If the answer is MAYBE, you may want to contact your local digital satellite dealer for information about having
a professional installer conduct a thorough site survey.
Elevation is the up/down angle that
the dish is pointed.
Azimuth is the side-to-side direction
that the dish is pointed. Tilt is the circular rotation of the dish itself, like a steering wheel.
Write down your site information here:
Azimuth Elevation Tilt
USING THE DISH POINTING MENU SCREEN
By simply following your satellite receiver’s on-screen menufeature, you can obtain the precise dish pointing coordinates
for your location. These coordinates include Azimuth, Elevationand Tilt.

PRECISE SITE SURVEY
Based on your general site survey, you probably already know where you want
to mountyour dish, but it’sa goodidea to followthe procedures outlined inthis
section in order to make sure that your site selection is a good one.
1. Go outsidetoyourinstallsiteand holda compass flatin thepalmof your hand.
Hold your hand still until the needle stops moving (the dark or colored half of
the compass needle always points North).
2. Rotate the compass so that the “N” (for North) is directly under the dark part
of the compass needle. Your compass is now aligned with North. The marks
around the outside edge of the compass represent the azimuth degrees you
will point your antenna to.
3. Locate the tick mark on the compass edge that corresponds to the azimuth
number you wrote down. This is the direction of your azimuth setting (the
direction the dish willneed tobepointedtoreceivesignalsfrom the satellites).
Pick a landmark or lay down a stick in that direction for reference from the
mounting location.
4. Raise yourarm toapproximately the elevation angle recorded earlier to make
sure that there are no obstructions in the signal path. Use an inclinometer or
protractor to more accurately estimate the elevation angle.
5. Repeat this survey in several places on your property if necessary until you
find the best mounting location.
From this rough sighting, allow plenty of clearance for the final alignment.
Remember trees grow up and out, which may possibly block the signal in
the future.
Tip
Try to keep the compass away
from any metal objects. Metal
objects can cause inaccurate
compass readings.
WARNING
Do NOT install the dish near
power lines, electric lights or
power circuits. Contact with
power lines, lights or power
circuits may be fatal. It is
strongly recommended that the
dish be located more than 20
feetfrom overhead powerlines.

IMPORTANT! Take time to plumb the top straight section of the mast so it is vertical in
all directions before drilling the holes in the structure and after the Universal Mount
is installed. If the mast is not plumb, alignment to the satellite will be very difficult. See
Figure 2B.
• When attachingto wood framed structures, usethe two center inside holes inthe mounting base. They must be aligned
on the centerline of the stud or rafter. Attach with two ⁵⁄₁₆” x 3" lag bolts and flat washers (not included) screwed
into a ⁷⁄₃₂” diameter pilot hole in a solid wood structural member. Apply silicone sealant around bolt entry to prevent
water from entering the holes. See Figure 2.
• When attaching to masonry structures, use the four corner outside holes in base bracket and four appropriate ¹⁄₄"
double-expansion anchors or toggle bolts with flat washers (not included). See Figure 2A.
ANTENNA MAST MOUNTING AND ON-THE-GROUND DISH ASSEMBLY STEPS
In order to make assemby easier and safer for youandto avoid losing hardware,it is recommended
that much of the assembly work be done on the ground in a clear area. More importantly, to sim-
plify satellite alignment, the permanent tilt and preliminary elevation adjustments should also
be performed on the ground.
IMPORTANT! Some bolts may not fit into holes of painted metal parts due to an accumulation
of paintin the hole. This is not a product defect, but is a result of normal variation in the paint-
ing process. If you are having difficulty installing a bolt, tap the head of the bolt lightly with
a hammer to remove this paint and assemble the bolt.
1. On the universalmount assembly, insert (2) ¹⁄₄" x ¹⁄₂" long carriage bolts through the mast andbracket slotand capture
withan external tooth washer and flange nut. Install a #10 self-tapping screw for ground wire attachment. See Figure 1.
FIGURE 1
2. After the mounting location is determined, drill mounting holes in the structureto match the Universal Base Bracket.

15. Before making any wire connections, read “Connections”, Page 18. The next stepsinvolvemakingthecoaxialcable
interconnectionsbetweenthe LNBs,multiswitch andthe satellite receivers. First, choose one of the mounting location
options for the multiswitch listed belowthat best fits your installation. Use approvedinstallation kits with high quality,
lowloss RG6 coaxial cable to insure the best performance underall conditions. All coaxial cables must be grounded
outside at the point of entry. Contact a licensed inspector or electrician in your area for assistance. General ground-
ing requirements are outlined in Figures 11 and 12.
MULTISWITCH LOCATION OPTIONS:
• Option #1: Mounting a weatherproof multiswitch to the back of the antenna as shown in Figure 9. This location
is simplest for installations that use one receiver since only one cable enters the building. If this option
is selected, connect the LNBs to the multiswitch per the following instructions while on the ground with
coaxial cables. Depending on your model, a 4-cable setmay be included foreaseof installation.
• Option#2:Mounting themultiswitch insidethehouse.Thisoptionprovidesthe bestweatherprotectionandmay
provide the easiest access for future wiring changes, such as adding additional satellite receivers.
• Option #3: Mounting the weatherproof multiswitch under the building eaves at the point of cable entry. This
optionprovidesexcellentweatherprotectiontothewireconnectionsandtheswitch.Iteliminatesthecoaxialground
blocks since the multiswitch also serves as a grounding block for the four LNB cables connected to it.
NOTE FOR OPTIONS #1 and #3: Typically in a single family home, the RG6cable for the supplied 4x 4mulitswitch does
not exceed 100 feet from the satellite receiver(s) to the LNBs. For installations where each RG6 cable
runfrom the satellitereceiver(s)totheLNBsexceeds100feet,such asoftenencounteredina commercial ormulti-dwelling
building, it is recommended that you use an AC-powered multiswitch (not supplied). An AC-powered multiswitch
powers the multiswitch and the LNBs directly from an AC/DC power module so that the
satellite receiver is capable of driving a longer RG6 cable. Contact Channel Master Technical Service for an
Application Note concerning such installations. Other manufacturers may offer similar products.
16. Even though all the above mutiswitch location options are used by installers, this manual will concentrate on option
#1.If an installer chooses toinstall the multiswitchin the houseorat the pointofentry to the house,then cablesof proper
lengths must be cut. To prevent corrosion, weatherproof outdoor connectors with rubber o-rings must be used for
all outdoor connections. See Figures 11 and 12 for general wiring diagrams.
FIGURE 7 FIGURE 8

ON-GROUND INSTALLATION WITH MULTISWITCH ON BACK OF DISH - OPTION #1
1. To install the outdoor multiswitch to the back of the antenna, use the #8 self tapping screws and washers
provided in the multiswitch carton. CAUTION: Use a hand tool to tighten the screws until the face of the screw head is
evenly touching the multiswitch mounting lug – then tighten ¹⁄₄ turn more. You will also need 4 cables to make the con-
nections betweenthemultiswitchand theLNBs. Aset of gray cables is providedfor Option#1,inmost antenna models.
Thecables are routedfrom themultiswitchthrough the feed tubetotheLNBs asshown in Figure10. Thecables should
be dressed as shown using the cable clips provided in the hardware bag. IRD cables should be routed underneath the
gray cable set as illustrated in Figure 9 (one IRD cable shown in black). With the exception of the IRD cable, it may be
easier to perform much of this installation on the ground.

3. Pass one endof two coaxialcables(labeled “Sat A” on both ends) through the rectangular feed tubeontheside marked
“Sat A”.ThenattachthemtotheLNBthat willbemountedintheposition marked“Sat A”attheendofplasticLNBAdapter.
IMPORTANT! If labeled cables are not supplied, then mark two cables on both ends “Sat A” with masking tape.
4. Repeat Step 3for inserting the two coaxial cables(labeled “Sat B” on both ends) in theother sideof thefeed tube and
connecttothe second LNB that willbemountedin position marked“Sat B”. Tighten all cableconnectors on both LNBs.
See Figure 8.
5. Carefully push the LNBs and attached cables into the LNB Adapter all the way flush with the edge of the LNB Adapter
and secure with #8 insert nut and 1” long #8 phillips head screw and then tighten screws. See Figure 7. Slight
movement of LNBs after tightening is normal.
6. Connect opposite loose end of the cables labeled “Sat A” from “Sat A” LNB to the multiswitch “Sat A” terminals as
showninFigure 10. It does not matter which “Sat A”labeled cables connect to 13V or 18V multiswitch terminals–they
are interchangeable.
7. Repeat for connecting opposite loose end of the cables labeled “Sat B”to the multiswitch “Sat B” terminals as shown
in Figure 10. It does not matter which “Sat B” labeled cables connect to 13V or 18V multiswitch terminals. They are
interchangeable.
8. Install weather caps on all unused multiswitch connectors.
9. This completes the On The Ground Assembly work for Option #1. For Options #2 and #3, follow similar
applicable procedures in addition to Figures 11 and 12 as references.

GENERAL GROUNDING REQUIREMENTS
The universal mount and coaxial cables must be properly connected to grounding electrode(s) per National Electrical
Code (NEC) Sections 810 and 250, and per your local codes. For the three multiswitch options described, please see
top-level general grounding diagrams in Figures 11 and 12.
MOUNTING THE ANTENNA ASSEMBLY TO MAST
1. Slide the clamp/mount on the antenna assembly onto the Universal Mount mast and loosen/tighten the (2) azimuth
clamp bolts (see Figure 5A) and the elevation pivot bolt (See Figures 3 and 4) just enough that the antenna
assembly is set into the mast all the way until the top of the mast meets the elevation pivot bolt/spacer.
2. Tighten only the elevation pivot bolt. This will not restrict the azimuth (horizontal) rotation. If, after the antenna
assembly is already mountedon the antenna mast, and the elevation adjustment screws areloosened orthe tiltadjust-
ment screws are also accidentally loosened, tightening the elevation pivot bolt will prevent any extra free play of
the Az/El mounting assembly. See Figures 3 and 4.
3. Install quality RG6 cables from the satellitereceivers to the multiswitch. You may want to install one receiver first
until the satellite signals are acquired and fine tuned. Routing of receiver cables, if the multiswitch is mounted at
the back of the dish, is shown in Figure 9.

STEP-BY-STEP INSTRUCTIONS FOR ACQUIRING AND FINE
TUNING THE SIGNAL
1. Read the instruction manual that came with your satellite receiver or set-top
converter to determine how to access the on-screen signal meter.
The signal meter shows you when youhave lockedonto asatellite’s broadcastsig-
nal, andgivesyou thesignal strength.Itiseasiest to usethe signal meterwiththe
help ofanotherpersonto relay signal strength values toyou, or bymovingthe TV
displaying the signal meter so that it is easily viewed at the point of installation.
NOTE: Satellite A (101˚) has 32 authorized transponders from 1 to 32; all are
active. Therefore, the on-screen signal meter may be tuned to any of the 32
transponders for the initial dish antenna adjustment.
Satellite B (119˚) has 11 authorized transponders from 22 to 32; but a few of these
may be reserved for upcoming programming expansion. Tune your on-screen
signal meter to transponders 23, 25, 29 or 31 for the initial dish antenna
adjustment.
2. Makesure that you select thecorrect type of dish (oval,2 LNBs)onyour receiver
menu. The signal meter will give you the pointing coordinates for your antenna,
and valueswill depend on the typeof antennayou haveselected. Failureto select
thecorrectdish willresultinwrongpointing anglesaswellastheinabilitytoreceive
certain programming. Consult your receiver manual for additional detail.
3. Access the signal meter. Set signal meter to the 101° satellite (this might also be
represented on-screen as “Satellite A”). At this point you will probably not have
a signal.
a.Using a compass, point the antenna to oneside (left or right by a few degrees) of
the azimuth value foryour location.
b.Sweep the antenna towards and through the azimuthpoint by moving the dish in
approximately3 degreeincrements. Pause fora coupleof secondsandwait foran
updatedvaluefromthesignalmeter.Whenthesignalis foundandthesignalmeter
is locked onto a signal, go to step 4.
c.If, after sweeping the antenna com-
pletely left to right or right toleft and
thesatellitesignalisnotfound,adjust
the elevation +2 degrees and sweep
theazimuthagain. (Do notchange tilt
alignment setting.)
-16-
ACQUIRING AND FINE TUNING THE SIGNAL
Now that you have installed the satellite antenna and routed all of the cables, it’s time to acquire and fine tune the
signal. Before you begin, you may want to go outside and double-check the azimuth, elevation, and tilt settings on the
dish to make sure they correspond to the on-screen coordinates given by the satellite receiver.
• Make sure that the elevation indicator is aligned with the edge of metal, not the washer or bolt, per Figure 6A.
• Make certain the antenna mast is plumb, per Figure 2B.
• Use a compass to verify that the azimuth setting on the dish is correct and no obstacles are
between the dish and satellites.
Tip
If your receiver is not equipped
with the audible tone feature, you
may have a friend watch the
signal meter and relay the
strength reading to you.
Maximum Signal
Strength
While the maximum signal
strength is 100,the signal strength
you achieve will most probably
be less. Although there is no
difference in picture quality above
signal strengths of 60, the higher
the signal, the less likely you are
to experience signal outages
during adverse weather. For this
reason, it is important to obtain
the strongest signal possible.
Point center of the antenna
to the exact azimuth direction
according to your compass
Tip
If your receiver is equipped with
the audible beep tone feature,
make sure you have the strongest
possible signal(s) by moving the
dish until you get the highest
pitched beep tone. Consult your
receiver manual for detail.

-17-
d. If the signal is still not found, adjust the elevation -2 degrees from the original value (-4 degrees from the current
setting) and sweep the azimuth again.
e. If the signal is still not found, check to make sure the cables are connected correctly. Using a bubble level, verify the
Azimuth, Elevation and Tilt angles, in addition to making certain the mast is plumb.(Alignment may be difficult to
achieve if the mast is not plumb.) See Figure 2B.

If no signal is available, check the connections to the multiswitch.
6. Once again, sweep the azimuth until the signal meter value for satellite 119˚ is maximized, then adjust the elevation
to peak the reception for satellite 119˚. Make a note of the elevation and azimuth angles.
7. Switch signal meter to satellite 101˚ to make sure that the signal meter is locked for both satellites.
7a. Further maximize the signal strength on both satellites by finely adjusting the Elevation Adjustment.
8. Carefully tighten all of the elevation and mast clamp bolts, (See Figures 3, 4, 6A), trying not to move the antenna on
the mast while you do so. After tightening the bolts, make certain that the signal meter is still locked onto a signal for
all satellites and the signal value has not changed.
9. Professional installers may want to use alignment meters or equipment, such as the Channel Master Model 1006IFD
Dual Satellite Signal Level Meter, or industry equivalent, to speed up alignment and achieve maximum signal strength
on both satellites.

TROUBLESHOOTING FOR MULTISAT DISH ANTENNAS
Connections
1. IMPORTANT: Before installing coax cable, visually inspect the inside of each cable connector to make sure
that there is no dirt, moisture or any other foreign material in the connector. Also check to make sure that
the aluminum cable shielding foil or braid is not touching the copper center conductor. After inspecting the
inside of the connector and making any corrections, make sure that the copper center conductor is straight
and centered in the end of the connector.
2. Make surethat the two“Sat A” cables that are included with your antenna are marked ‘Sat A” on both ends.
The two “Sat A” cables connected to the “Sat A” dual LNB must go to the two “Sat A In” connectors at the
multiswitch. Any one of the two “Sat A” cables can go into any one of the two “Sat A In” connectors at the
multiswitch.
3. Make sure that the two “Sat B” cables that are included with your antenna aremarked “Sat B” on both ends.
The two “Sat B” cables connected to the “Sat B” dual LNB must go to the two “Sat B In” connectors at the
multiswitch. Any one of the two “Sat B” cables can go into any one of the two “Sat B In” connectors at the
multiswitch.
4. “Out 1”, “Out 2”, “Out 3”, and to “Out 4” are all identical multiswitch outputs to the satellite receivers.
5. RG6 cable must be used for installationfrom the dish to the receivers to achieve optimal signal levels. RG6 cable
have less signal attenuation than the existing RG59 cables sometimes found in a user’s home.
6. Exisitng TV-specific components, such as TV splitter, etc. may not perform properly. When unsure of
installation, remove such components and reduce the installation to the basic connections called out in the
installation manual.
7. Make sure the satellite receiver operating manual is properly followed, in addition to the dish antenna installa-
tion manual. Make sure the DIRECTV Access Card is fully inserted in the card slot of the receiver.
8. Make sure all the cable connections are securely tightened/fastened from the LNBs to the multiswitch, from the
multiswitch to the grounding block (s) and then to the “Satellite In” jack at the receiver. This is also critical for
preventing any cable conductor corrosion in the future.
Pointing
1. Make sure the correct numbers, by Zip code, are used for the “tilt” (dish angle rotation), “elevation” (vertical
up or down) and “azimuth” (horizontal left or right) for the installation location.
2. Beforethe dish antenna ismoved to the antenna mast, use the receiver’s on-screenpointingmenu to fix the “tilt”
setting by following the procedures found in the dish antenna installation manual. Once the signal is acquired,
the Elevation Adjustment setting may need to be fine tuned to maximize the signals.
3. The most critical procedure is the proper plumbing of the dish antenna mast. It must be plumb and level,
otherwise the acquiring of both satellites is difficult and even if the satellites are acquired, it may not be an
optimum setting and is therefore prone to rain, snow, wind outages.
4. When using a compass to set initial “azimuth” as indicated by the receiver’s dish-pointing menu, make sure the
compass is not falsely deflected by any nearby metal object(s).
5. Make sure there are no obstructions between the dish antenna and the satellites, for the settings of “tilt”,
“elevation” and “azimuth” at the installation location. Trees may have to be trimmed periodically if they grow
too close.
6. Slowly rotating the dish antenna left and right of the required “azimuth” until the receiver’s on-screen meter
indicates strong signals for both satellites.

-19-
TROUBLESHOOTING FOR MULTISAT DISH ANTENNAS (continued)
7. If all have been done correctly but the system is still not aligned optimally, slightly change the “elevation”
adjustment of the dish antenna and repeat the procedure. The “tilt” must be set for a given installation
location by Zip code, per receiver’s on-screen menu, and must not be changed.
Temporary Loss of Signal
1. If there is an unusually heavy rainfallin theinstalled area, thesignal maybe lost temporarily. Anoptimally aligned
dish antenna minimizes the chances of “rain fades”.
2. Make sure the dish antenna is mounted securely to prevent it from being permanently blown out of the correct
position in heavy wind.
3. Until it is removed, heavy snow accumulation on the LNBs or the dish may reduce the satellite signal strength.
4. A dish antenna with tree foliage in the line of sight to the satellite may have a good picture on a clear day,
but no picture with a slight rain.
Receiver
Your receiver requires adequate ventilation. It should not be stacked with other entertainment units such as VCR
and stereo. If stacking is needed, the satellite receiver should be on the top of the stack. Otherwise the receiver
may fail, which could lead to troubleshooting in the wrong area.
Installed System
The 4x4 multiswitch, which issupplied withthis system, is powered directly fromthe satellite receiver(s),thusoffer-
ing greater flexibility in locating the multiswitch as described in the preceding pages. Nevertheless, the longer the
cable length, the higher the DC and the signal attenuation.Though rarely encountered in a single familyhome, cable
lengths longer than 100 feet, from the satellite receiver to the LNBs, should be avoided.
For installations where the RG6cable run from the satellite receiver(s) to the LNBs exceeds 100 feet, such as often
