3-3.6.2 Selecting a Proper Location for the GPS Antenna
GPS satellites transmit their special signals in the 1575 MHz range: such signals do not penetrate
conductive surfaces. When selecting the location of the GPS antenna, you should also be aware that
strong local interference as well as reflections from nearby objects may disrupt normal reception and
degrade the signal quality.
Thus, the GPS antenna should be installed on horizontal surfaces, in a place that provides a clear view
of the sky, which, in as far as possible, is not obstructed by large objects. For example, the roof of the
passenger’s cabin is a good place for the GPS antenna.
Moreover, you should not park the vehicle under dense foliage or other cover, for example, in a
garage, if you want to get a position fix from your GPS receiver.
NOTE
When the GPS antenna is installed on a metal surface for prolonged
periods, care must be taken to insulate the antenna, to prevent
galvanic corrosion.
After installing the antenna, route its cable to the GPS connector on the rear of the Micom-Z, and
make sure to avoid running it parallel to the other transceiver cables.
3-3.7 Cooling
Micom-Z units are cooled by free air convection. Therefore, make sure that sufficient free space is
available around the equipment to enable free air flow.
When it is necessary to use Micom-Z in applications that require continuous transmission for
prolonged intervals, it is recommended to install Micom-Z on the optional cooling tray.
