Antenna care and placement
Warning! Please ensure that power is disconnected from the unit before
connecting the antenna.
Since the GDW-11 is installed in a fixed location, special care must be taken
when planning the installation, especially when placing the antenna. The standard
antenna shipped with the product is an efficient dual-band antenna designed for
the GSM900 and the GSM1800 bands used in the European and most-Asian
countries.
Depending on the installation location and surrounding materials, the signal
strength reaching the GDW-11 may not be sufficient. The best way to find the
optimal position of the antenna is to use the Westermo GD-Tool to measure
the “received signal strength”.
The antenna must only be connected locally and not connected to a cable
distribution system going outside the building.
