5. Installing/Positioning the Antenna:
For best reception, the supplied antenna should be
placed near a window if in the house or, if outdoors,
in an open area and as high as possible; some
repositioning may be required to achieve optimum
results. The following guidelines are recommended:
a. In a major city, where Sirius ground repeaters are
present, you can usually place the antenna away
from a window and still achieve the desired results.
b. You can also place the antenna outside (on the roof
structure), provided it is clear of any overhead
obstructions. Because of the orbiting characteristics
of the Sirius Satellites, the strength of the received
signal may change over time. In most cases
however, the signal should be available continuously.
If you experience a loss of signal or audio, reposition
the antenna inside the home or outside as necessary.
6. Antenna Placement Considerations
The antenna should be placed on a relatively flat
surface whenever possible. When outdoors, the
antenna may be left in its mount atop the Boombox
provided no overhead obstructions are present.
To mount the antenna:
a. Plug the antenna into the ANT connector on the back
of the SB4000 Boombox. Leave the antenna in place
on the Boombox, or remove the antenna from its
mount, uncoil the antenna lead, and place it at the
preferred location inside or outside the home. If no
audio is heard, move the antenna to different
positions until an audio output is heard. This is the
desired antenna position.
b. After determining the optimum antenna position, turn
OFF the SB4000 Boombox and SR4000 Receiver
c. Disconnect the power adapter from the wall outlet
receptacle.
d. Plan the routing of the antenna cable to the SB4000
ANT input when indoors. Make sure you avoid any
obstructions that could crimp, kink or twist the cable.
If the antenna is mounted outside, route the cable
from the antenna position to the interior of the home,
working the cable through the basement, under a
6
7
window sill, etc. Make adjustments and take up slack
whenever necessary.
e. Plug the antenna cable into the ANT connector on the
back of the SB4000 Boombox.
f. If not using battery power as the primary power
source, plug the female end of the AC Power Adapter
into the DC 12V receptacle on the rear of the SB4000
Boombox.
g. Insure that the AC Power Cable is securely inserted
into the AC Power Adapter. Plug the AC Power Cable
into a 110-volt receptacle. Turn ON the SB4000
Boombox and SR4000 Receiver.
You are now ready to enjoy Sirius programming
outdoors or within your home.
