a. Positioning the XM Antenna
The antenna supplied with the Xpress XM® Home Kit is a
high gain type that can receive XM’s signal from one of XM®’s
satellites and/or, depending on where you live, XM®’s terrestrial
repeaters. It is recommended that the antenna be positioned near
a south-facing window or outdoors with a clear view of the south
eastern sky in order to receive the satellite signal. In some cases,
it will be possible to receive XM®’s signal through standard home
walls or a roof. To position your antenna, first set up the home
system as described earlier in this installation guide. Next,
position the antenna until you receive the strongest possible
satellite signal. If the satellite signal is not available, you can
optimize it for a terrestrial signal (where available).
b.Indoor installation on a flat surface
To aim your antenna at the satellite:
1. Set antenna flat against its base on a flat (horizontal)
surface.
2. Turn the base of the antenna so that the XM® logo is
facing to the south if you are in the eastern half of the U.S.
and to the south/southeast if you are in the western half.
3. Use the “Antenna Aiming” screen, as described on the
previous page, to optimize antenna tilt angle and position.
4. If necessary, experiment with different locations near a
south-facing window or outside.
