Antenna Installation Options:

A. Typical Antenna Installation:

Indoor installation on a flat surface

To aim your antenna at the satellites:

1. Set the antenna flat against its base on a flat (horizontal) surface.

2. Turn the base of the antenna so that XM Logo is facing to the
South/Southwest if you are in the Eastern half of the US, and to the
South/Southeast if you are in the Western half of the US.

3. Use the “Antenna Aiming” screen, as described in the owner’s manual,
to optimize antenna tilt angle and position.

4. If necessary, experiment with different locations near South-facing
windows.
Your High-Gain Home Antenna comes with 20-feet of cable. If that is not
sufficient to locate the antenna where there is a strong XM signal, please
see the section below on extension cables.

Outdoor installation or Indoor Wall Mounting

The antenna can also be attached vertically to an external or internal wall
if that is more convenient than placing it on a horizontal surface.

1. Holding your antenna up, find a wall location that ensures a strong
signal. It is recommended that you use an extension cord to temporarily
locate your High-Gain Home Antenna outdoors while optimizing the
antenna location with the “Antenna Aiming” screen.

2. Attach four screws to the wall using the Screw-Locator Pattern in
Figure 3. Use screws with head sizes small enough to fit in the center of
each of the four holes but large enough not to pop out of the elongated
sections. Leave 1/8-inch of the screw shanks behind the heads sticking out
of the wall.

4. Tilt the antenna fully back on the base, place the antenna base on the
four screw heads with the antenna pivot at the top and pull down
approximately 1/4-inch until the base is firmly secured. Note that the XM
Logo will be upside down when the antenna is properly installed.

5. Tilt the antenna away from the wall/base until the signal strength is
optimized.

NOTE: Do not cut the antenna cable and attempt to splice it or attach
alternative connectors or cable. The cable and connectors used in your XM
Reference Tuner are specifically chosen and attached at the factory to
ensure that they will work with XM’s unique frequency band. Your High­Gain Home Antenna comes with 20-feet of cable. If that is not sufficient

XM-EXT50

to locate the antenna where there is a strong XM signal, please see the
section below on extension Cables.

B. Extension Cable:

Your High-Gain Home Antenna comes with 20-feet of cable. If that is not
sufficient to locate the antenna where there is a strong XM signal, purchase a
50-foot cable extension (Polk Audio recommends the Terk XM-EXT50) from
Polk Audio (http://shop.polkaudio.com

) or your local retailer. Up to two

extensions can be used together for a total of 120-feet of cable.

The Terk XM-EXT50 cable is 50-feet long, weather resistant, and has a built
in signal amplifier to match the input gain with the XRt12 XM Reference
Tuner.

C. Prewire installation:

Prewire installation can be accomplished by using the 50-foot extension cable
(Terk XM-EXT50) to route from the XRt12 Tuner location to the desired
antenna location. The Antenna that comes with your XRt12 tuner has 20-feet
of cable and up to two extension cables can be used for a total antenna cable
length of 120-feet.

For installations that require cables longer than 120-feet, we do not have an
adequate solution at this time. We are working with Terk to develop a
solution in the near future. Please contact us if this is a requirement for your
installation.

D. Antenna Splitters:

With the use of the Terk XM-SP you can connect two XRt12 units to a single
antenna cable.
