d) Antenna installation should be avoided in close proximity with other receivers or transmitters likely
to cause interference.

7.4.2 Install GPS antenna for HiperMAX ATCA
Install the GPS antenna for the HiperMAX ATCA using a 16 m standard cable and optional pole
mount bracket.
The first consideration for a GPS antenna is a clear view of the sky, preferably 360 degrees. The
GPS antenna should be attached to a suitable mast.
Use the guidance below to find the optimal position for mounting the GPS antenna:
a) The antenna must be mounted in an upward position.
b) The antenna should be installed at the highest possible point available at the site. This is to ensure
minimum obstruction from any surrounding obstacles (trees, buildings or other installations, etc.).
c) To avoid influence of reflected waves, the antenna must not be installed less than 2m away from
metallic objects with a dimension greater then 20 cm.
d) Antenna installation should be avoided in close proximity with other receivers or transmitters likely
to cause interference.
e) The antenna should be positioned to minimise the risk of a lightning strike. See Lightning
Protection Overview for guidance on placement.
7.4.3 Mount the GPS Antenna
The GPS antenna bracket can be optionally mounted on a Pole up to 40mm (1.5"). The Antenna
screws on to the 25m threaded tube.
