Positioning of the antenna
Before you begin installing the GSM module, please decide on a suitable position for the
antenna. When doing so, pay attention to the antenna's cable length.
The following points will enhance signal strength and must be considered:
Note
Install the antenna so it is as
high
as possible.
Install the antenna so it is as
far
as possible from the alarm system.
Maintain a
distance of at least one metre
from metallic objects
(steel beams in the wall, lines, pipes, metal cabinets etc.).
Make sure that at least 25 cm of the cable leads horizontally from the
antenna. (See figure)
