3 General Instructions

3.3 Shortening the antenna “tail”

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 im portant to
read these “Instructions” carefully to ensure
that the antenna is mounted properly in the best
location in order to provide optimum reception
quality.

3.1 Mounting location

The satellite antenna should be mounted hori­zontally on a metal surface measuring at least
18 inches by 18 inches. The best reception
qual ity is achieved at the highest point of the
vehicle (i.e. the roof) but the trunk lid is an al­ternative 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
unobstru cted location (i.e. clear of roof racks,
sunroofs, other antennas). Use the table below
as a guide for the required distance (A) between
the antenna placement and a possible obstruc­tion with a height of (B).

The antenna module is supplied with a 6 inch
tail. For vehicles with flat roofs (SUV’s, Mini­vans) and for convertibles, it is possible to
shorten the tail by up to 2 inches.

For vehicles with a sloping roof, or if the
module is mounted on the trunk of a sedan,
the tail should not be shortened!

As soon as the precise length of the tail has
been determined, the adhesive strip may be cut
to length and applied to the antenna tail.

(Glass sunroofs, which open outwards and
cover the rear roof area, should not affect the
location of the antenna module).

3.2 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.

3.4 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.
