TROUBLESHOOTING FOR MULTISAT DISH ANTENNAS
C o n n e c t i o n s
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 sure that 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 are marked "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 installation from 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 perf o rm pro p e r l y. 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.
P o i n t i n g
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. B e f o re the dish antenna is moved to the antenna mast, use the re c e i v e r 's on-screen pointing menu 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.
