Introduction
Your Sirius satellite antenna, approved by Sirius Satellite Radio, Inc., has been specially designed to receive signals from Sirius' three satellites and Sirius' network of
ground-based "repeater" transmitters.

General Instructions
Satellite antennas are extremely sensitive and finely specified to facilitate reception
of satellite signals under a variety of conditions across the whole of North America.
It is important to read these instructions carefully to ensure that the antenna is
mounted properly in the best location in order to provide optimum reception quality.
Mounting location
The satellite antenna should be mounted horizontally on a metal surface measuring
at least 18 inches by 18 inches. The best reception quality is achieved at the highest point of the vehicle (i.e. the roof) but the trunk lid is an alternate location for
convertibles and for some sedans.
It is important that the antenna has a clear "view" to the satellites and ground-based
repeaters and should therefore be mounted in an unobstructed location (i.e. clear of
roof racks, sunroofs, other antennas). Use the table below as a guide for the
required distance between the antenna placement and a possible obstruction with a
given height.
(Glass sunroofs, which open outwards and cover the rear roof area, should not
affect the location of the antenna module).
Installation temperature
Installation should be carried out when conditions are at room temperature or
above. Firstly, colder temperatures could affect the curing time of the antenna module's adhesive. Secondly, when mounting the antenna module on a sedan, it will be
easier to work with the rubber molding around the window.

Shortening the antenna "tail"
The antenna module is supplied with a 6 inch tail. For vehicles with flat roofs (SUVs,
Mini-vans) and for convertibles, it is possible to shorten the tail by up to 2 inches.
NOTE: For vvehicles wwith aa ssloping rroof, oor iif tthe mmodule iis mmounted oon tthe ttrunk oof aa
convertible, tthe ttail sshould nnot bbe sshortened!
Figure 4: Shortening the antenna tail
After the precise length of the tail has been determined, the adhesive strip may be
cut to length and applied to the antenna tail.

Removing the antenna
The antenna module may be removed, using a nylon cord (e.g. fishing line) to cut
through the adhesive pad between the antenna module and the vehicle. Work from
the front to the tail in a side-to-side cutting motion. Any remaining adhesive may be
removed with an appropriate cleaner.
